Part# UP95G - Heavy Duty Lift Pump for Cummins ISC & ISL CAPS Fuel System

***Our price includes technical assistance for installation***

Note: This pump will not have the correct fittings or fuel hose in it for an RV application since they are all different, you will need to source fittings and hose locally. Included is the wiring harness, pump and mounting bracket.

Applications:

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

This heavy duty adjustable fuel pump is designed to meet the demands of the added strain of a performance module on the CAPS fuel system. The CAPS fuel system is known to be a weak fuel system as the factory lift pump only engages for the first 30-45 seconds after the key-switch is engaged. After this, the CAPS pump "pulls" the fuel and acts as the only pump in the system. By adding this heavy duty pump, not only are you taking away a lot of stress on the CAPS pump but you are also providing a steady flow of fuel that will help cool and lubricate the pump to increase the reliability and longevity of the CAPS pump. This adjustable pump is rated at 95 gallons of diesel fuel per hour and come preset at 15 PSI. Using a 1/8" Allen plug, you can make a quick clockwise adjustment to increase pressure or counter clockwise to decrease pressure.

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.
