High-Flow 95 GPH Lift Pump Upgrade for Cummins CAPS Fuel Systems


The UP95G Heavy Duty Lift Pump is designed to improve fuel delivery and reliability for Cummins ISB, ISC, and ISL engines equipped with the CAPS fuel system. The factory CAPS system is known for placing significant strain on the injection pump because the original lift pump only runs for approximately 30–45 seconds during key-on, after which the CAPS injection pump must pull fuel on its own.

By installing the UP95G high-flow lift pump, you provide a continuous supply of fuel to the CAPS injection pump, reducing stress on the system while improving cooling and lubrication of the injection pump. This helps increase overall reliability and extend the life of the expensive CAPS pump.

The pump delivers 95 gallons per hour of fuel flow and comes preset to 15 PSI, with the ability to easily adjust fuel pressure using a 1/8" Allen adjustment screw. Increasing pressure requires a clockwise adjustment, while counterclockwise adjustment lowers the pressure.

This heavy-duty pump is particularly beneficial for vehicles running performance modules or performance tuning, where increased fuel demand can further stress the CAPS fuel system.

The kit includes the pump, wiring harness, and mounting bracket, allowing flexible installation in a variety of applications. We also provide technical assistance when installing.

Product Benefits:

  • Helps reduce strain on the CAPS injection pump
  • Improves fuel cooling and lubrication of the CAPS pump
  • Ideal for engines running performance modules or tuning
  • Includes pump, wiring harness, and mounting bracket

Applications:

  • 1998.5–2003 Cummins 5.9L ISB (275 / 300 HP) – VP Fuel System
  • 1998.5–2005 Cummins 8.3L ISC (315 / 330 / 350 HP) – CAPS Fuel System
  • 1998.5–2003 Cummins 8.9L ISL (380 / 400 HP) – CAPS Fuel System

Specifications:

  • High-flow 95 gallons per hour (GPH) fuel delivery
  • Preset at 15 PSI with adjustable pressure control

Special Notes:

  • RV fuel systems vary in plumbing configurations. This kit does not include fuel fittings or hoses, which will need to be sourced locally for proper installation.

I purchased a UP95G Kit from you on 8-24-2021 invoice #53642. It has worked flawlessly for the past 3 years. I am now having a starting issue 50% of the time. Sometimes the engine has to crank for about a minute before it starts. I don't think there is a problem with the Fass pump. My question is I have misplaced the installation instructions you sent in this kit. I was wondering if you could send me another copy of the instructions, so I can refresh my memory how I installed this UP95G kit.

Thank you ( Gary Henderson, 09/04/2024 )
We would be happy to help, please call in (800-417-4559) and ask to speak with Alan for technical assistance.
Is overnight shipping available to Alabama on this item? ( Mark Floyd, 07/24/2024 )
Yes, overnight is available as long as the product is in stock and the order is placed before 2pm PST.
Good Morning. I have the same setup ast Ed with the rear mount filter setup away from my lift pump. My factory lift pump already had a massive leak that i had to re-seal, and I want to upgrade to a FASS pump. Online I've found lots of different options and setups. Can you post or e-mail the instructions for this pump, so I can look at them before purchase? Or possibly post more pictures from different applications showing how this was installed? I think posting at least the instruction on the page will help answer a lot of the questions on here.

Thanks for the support.

We provide printed instructions with the kit as well as technical assistance when installing, if needed.
Can you provide a copy of the installation instructions? It would help me determine at what level this DIY project is (for me).

Thanks!
John ( John Gates, 10/06/2023 )

This installation consists of

  • Mounting the pump with a provided bracket and hardware (drilling four 1/4" holes at the mounting location).
  • Finding an ignition power source at the back of the coach to attach the signal wire.
  • Connecting power and ground at the battery.
  • Having fuel hoses made locally and attach them to the Fass pump between the primary and secondary filters (this is where the factory lift pump is plumbed in normally).
  • Abandon and cap off the fuel lines that go to the factory lift pump.

Hope that helps! We sell a ton of these to RV owners that install them without issue. (It's not a bad install if you have fairly good access to the filter locations).

Why is it recommended to install a Heavy Duty Lift Pump after you installed a AG Power Module.Is it to insure constant fuel pressure to th injector pump! ( Rick Hinrichsen, 08/05/2023 )
The CAPS fuel delivery system is known to have issues that are mainly caused by low fuel pressure. The heavy duty lift pump ensures that good fuel pressure is always being supplied to the CAPS pump.
