Dear Valued Customer,  
“Made in the USA” is not just a slogan at FASS; it’s what we live by!  FASS is not only assembled in the USA but 98%+ of the FASS product is manufactured in the USA, helping to employ Americans and strengthen America.  At FASS, we scrutinize our suppliers and demand the highest quality American-made components.  However, this does come at a price, which is one of the main reasons FASS products are more expensive than the competition.  Remember price does not dictate quality but quality does dictate price! Here at FASS, we believe it’s worth the commitment and will continue this practice to support America!  Our com-petition is doing exactly the opposite by using foreign-made components.

Building extremely “High-Quality” fuel products is our business.  We concentrate all of our efforts in this arena.  No one else is as specialized as FASS in what we do!  This is one of the ingredients to insure you are running with the “Highest-Quality” fuel system in the world!  We have implemented very rigorous testing procedures to provide the “Highest Quality” we have become known for.  Not only is our product superior, but customer satisfaction is #1 at FASS.  It is our goal to provide the best service possible.  Our confidence is evi-dent in the products we make as each product is backed by an industry leading warranty!  

Our R & D department, in conjunction with our Dealer Support department, is continually searching for ways to improve quality, expand our product line, and provide superb support to our network of dealers so our customers’ needs and expectations will be exceeded.  

To help insure you receive the proper system and customer support at the local level, FASS has a VIP and Authorized Dealer network representing FASS products.  This is one reason you must purchase through a dealer to comply with our warranty policies.  If you do not, there is no warranty!  We recommend you go to, click “Find A Dealer”, put in their ZIP code, select the type of dealer, and see if the company you purchased from is listed.  If they are not, put their phone number in the field below the ZIP code field to see if they are listed.  Below these two fields is a list of “Terminated/Unauthorized” dealers.  You may want to review this list.  If the company is not listed or is on the “Terminated/Unauthorized” list, we suggest you return the product immediately to that dealer and call FASS.  We’ll recommend you to the nearest dealer.

VERY IMPORTANT:  Make sure to fill out your product registration form and return the original form to FASS Fuel Systems within 30 days of purchase accompanied with a copy of the purchase receipt. Complying with these guidelines will qualify you for the Extended Warranty!

See the Owner’s Manual for full Limitation of Warranty.  In the event that the buyer does not agree with this agreement: the buyer may promptly return this product, in a new and unused condition, with a dated receipt, to the place of purchase within thirty (30) days from date of purchase for a full refund less shipping.

The installation of this product indicates that the buyer has read and understands the Limitation of Warranty agreement and accepts its terms and conditions.



We expect every FASS System to exceed your expectation. Customer satisfaction, your satisfac-tion, is the all-important ingredient for success to our business, as it is in any other.
Normally, technical issues can be resolved by your dealer’s service department, as they can usually inspect the situation physically. If you’re not satisfied with the dealership’s response you can either email or call FASS.

Installing the improper FASS Fuel Pump can cause severe engine damage.
This installation manual applies to the T C10 095G or T C10 150G contained in the same package. The serial number on the installation/owners manual package should match the serial number on the outside of the box. If it doesn’t, call your dealer.

This T C10 095G or T C10 150G applies to this application:

Recommendation: T C10 095G – GM Duramax 2001-2010, with stock to oderate horsepower modifications.

Recommendation: T C10 150G – GM Duramax 2001-2010, with moderate to xtreme horsepower modifications.

Because of the higher fuel flow these systems have to offer, you may encounter problems with the stock fuel module. FASS can solve this issue with a Suction Tube Kit.



TIP!  lush and clean all brass fittings and fuel line free from debris.


WARNING!  Use care not to drill into any electrical wires, air lines or other damageable com-ponents when drilling.

WARNING!  Consult vehicle manufacturer’s instructions concerning the electrical system be-fore attempting any electrical connections.

CAUTION:  Wear safety glasses when operating power tools such as drills and grinders or when using a punch or chisel.

Use caution when installing the FASS Fuel System keeping debris from entering the internals of the system. Getting debris in the water separator nipple can lock up the motor. If the motor does lock up from debris call FASS for technical assistance. 100% of the FASS Fuel Systems are vigorously tested, which includes (but not limited to) wet testing for pressure, amps, flow, & including total all around performance before being shipped. 



The installation of the FASS HIGH PERFORMANCE FUEL PUMP can be relatively simple when the following steps are followed.

1.    Inventory the package components completely. Notify the place of purchase immedi-ately of any parts missing or damaged.
2.    We have invested many hours into the development of the installation manual to simplify the installation of the FASS Fuel Pumps. Please read the installation manual completely before attempting installation. Understand how the system operates and installation rec-ommendations before beginning installation. Most of the questions that you will have will be answered in the manual. If you have a question please review the installation manual.
3.    The installation recommendations contained herein are suggested installation guidelines only. Each installation can and may vary considerably because of the many options and accessories available to the truck market.

Installation personnel should use good judgment and common sense when installing the FASS High Performance Fuel Pump.
If any installation procedure is uncertain, contact FASS technical support.
Due to training, communication, and our relationship with our authorized dealers, we recom-mend an authorized FASS Fuel Systems dealer for the installation. They are prepared to in-stall the FASS fuel pumps with the most efficiency. If a situation/problem arises during the installation, they are the most prepared for that situation/problem. It may take more time for an unauthorized shop to address the situation/problem. We are not responsible for any instal-lation mistakes.



95 OR 150 GPH


A fuel pressure gauge is highly recommended to identify fuel filter life and to prevent engine damage!





Note:  The installation of the electrical harness is done first, allowing power to be applied to the pump for lubrication purposes later in the installation. 

a. The red wire of the WH-1001 wire harness will travel thru the rubber grommet in the firewall or into the fuse panel in the engine compartment.

Note: Connect the fuse tap to the hot side of the fuse. Use a test probe to locate the “hot side” of the circuit in the fuse block.

c. Using the fuse tap & flag terminal, connect the red lead to a terminal on the circuit board that is “hot” when the key is on.

Note:  The use of a corrosion preventative on electrical connections is rec-ommended.

d. Green wire must be connected to a clean ground without being exposed to any corrosion, preferably the negative battery terminal. Secure fuse block in a location protected from outside elements. any corrosion, preferably the negative battery terminal. Secure fuse block in a location protected from outside elements.

Note: Completion of this step will be addressed in the Mounting Step 3.

e. Route wire harness along frame rail to mounting location of pump.








Note:  If necessary to gain access to the top of the fuel tank, carefully bend the sheet metal down that is covering the side.

a. Remove the drive shaft to gain access to the top of the fuel tank.

Note: Bed is removed for clarity.

b.    Using a 1/2' fuel line disconnect tool, remove the factory suction line on the fuel tank. Place the disconnect tool around the fuel tank tube and slide the tool under the fuel line connection to release the fuel line.

c.    With the factory suction line removed, install the QD-1002 Quick Dis-connect and a supplied 1/2" clamp onto one end of the 1/2" fuel line and tighten. Oil the O-rings inside the QD-1002 and slide onto the suction port on the fuel tank.


WARNING! Some models have an integrated over-flow tube inside the filler neck. If your filler neck does not have a separate over-flow tube, you have an integrated filler neck.

d. Some filler necks have the over-flow tube inside. Mark location for the Return manifold on the rubber filler neck. Loosen the clamps on both ends of the filler neck and remove screws from fuel receptacle. Remove filler neck assembly. Slide rubber outer hose down exposing breather tube. At mark, cut hose. Slide top half over-flow tube with HC-1003 clamp. Slide RM-1001 Return Manifold over the over-flow tube and into filler hose with the small junction pipe pointing toward the fender. Slide another HC-1003 clamp and bottom hose over tube and secure. Re


Prepare FASS return line by cutting rubber junction connecting the two halves of the filler neck.  Position RM-1001 with the 1/2” junction pipe aiming to outside of bed. Clamp rubber and RM-1001 using both HC-1004’s.


e. Position RM-1001 with the junction pipe aiming to outside of bed. Connect rubber and RM-1001using both HC-1004’s.






a. Using thread tape, install the 10-298 into “E” and the 10-299 into the “T” port (on opposite end).


b. Attach BR-2001 to back of system using 5 1 1/4” Hex bolts and WA-2001 spacers. Torque to 110in/lbs.


Note: Review Step C & D to complete properly.

c. Assemble the FASS pump brackets using the RS-1001 spacer between. Hold pump up to the mounting location for rough fitting. Once location is established, use template on back of manual to accurately mark drill points.

d. Position the pump assembly at the mounting location and check for fit. Review mounting to bed support, then if necessary review mount to leaf spring support as seen in the photo’s. The combination of Frame Brackets gives options as to mounting location.
