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. ( Support )
Can you provide a copy of the installation instructions? It would help me determine at what level this DIY project is (for me).
Thanks!

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. ( Support )
I purchased a UP95 G system from your company 8/2021. Has been working fine until about a month ago. I have a electronic fuel pressure gage installed. Every once in awhile the fuel pressure gage would peg to 30 psi for a second or two. I have the pressure set at 17-18 psi at idle, out on the road it fluctuates from 10-14 psi. i just drove 30 miles home and half way the pressure peg to 30 psi and stayed their. Motorhome ran fine no warnings. When I shut coach off and turn ignition back on pressure pegged to 30 psi. With ignition off it reads zero. I going to temporarly replace electronic sending unit with a manual gage to rural out electronic gage. Any ideas what else I should look at?

Without a change in the engine operation, and the intermittent nature of the issue, it sounds more likely to be an issue with the gauge or sending unit. ( Support )
Does this come with installation instructions please?

There is only one fuel filter in the system and it is between the lift pump and the low-pressure gear pump.
Do you disconnect the harness at the OEM lift pump and connect it to the new harness and connect the other end to the new pump?
Can the new pump’s inlet line be teed to the OEM lift pump’s tank supply line, and the new pump’s output line be teed to the OEM lift pump’s output line?
( Kenneth Brooks, 02/06/2023 )
This kit replaces the factory lift pump function, and runs constantly when the ignition is on. It has a separate stand alone harness to operate the new pump. The factory lift pump is left in place and the engine still uses the factory return lines. The fuel feed ports on the factory pump are no longer used and plugged. The new pump would then be plumbed in place of the old pump for the fuel feed. ( Support )
If this pump fails will this cause a restriction in flow or would motor home continue to run as normal? You mention factory lift pump could be left install. Would it be disconnected electrically, possibly could be hooked back up if new pump failed?
( Ricky, 12/08/2021 )
This pump does not have a bypass check valve integrated into it so it would create a restriction. You would be using the electrical connection from the old lift pump for the new, so I suppose you could plug the old back in but you'd still have to plumb it back into the system. If this is a worry for you, a simple bypass hose with check valve that goes around the pump could be installed. ( Support )
I purchased UP95G for my 2000 cummins 8.3 ISC , what is the optimum fuel pressure for the FASS pump to be set at?
( CHRIS RIDDLE, 04/20/2021 )
16-18 PSI is optimal. ( Support )

you said it replaces the factory lift pump and factory pump only runs for 30 seconds. with that said how are you making it run all the time. if cutting into factory harness how hard is it to do. where at in the harness are you cutting at?
( KENLEY CARSON, 04/17/2020 )
The wiring harness we provide has the provisions built into it to demand the pump to run all the time and it does not require you to cut any wires. ( Support )
does this replace the factory lift pump or a addition to factory lift pump?
( KENLEY CARSON, 03/26/2020 )
This replaces the stock lift pump. ( Support )
1999 Country Coach 8.3L ISC. Just checking for clarity, this pump is to be installed between the factory filters, with the factory Carter lift pump still in the circuit? No additional return hose needed etc...? Thanks!
( Johnny k , 12/28/2019 )
Yes, that is correct. We like to plumb them between the primary and secondary fuel filters and leave the OEM lift pump in place to utilize the fuel return line. ( Support )
How many amps does UP95G - Heavy Duty Lift Pump pull thanks
( Barry, 08/15/2019 )
This pump is pretty low amperage, between 3-7 amps is the specification. ( Support )
Do you place pump after primary filter even though fuel tank is 30 ft away thanks
( Bob, 08/14/2019 )
We prefer to install between the primary and secondary filters. The distance from the tank is no issue for this pump. ( Support )
2004 H R Endeavor 8.3 isc engine serial number is 46307911, Cummins saysThe OEN Pump transfer P/N 4935013 would not support a different pump for your Engine are they incorrect or talking about something different
( Barry Howard, 08/12/2019 )
The OEM pump is the only option that Cummins will say is compatible. The FASS pump that we offer is aftermarket so they would not recognize this part as correct even though it will work. ( Support )
Will this lift pump work with my 2004 8.3 isc engine serial number is 46307911
( Barry, 08/12/2019 )
Yes, you have a CAPS fuel pump system so this would work. ( Support )

Hi I was looking at one of your lift pump it's rated at 15 psi I've been looking everywhere for my engines PSI range and I can't find it.
I even called coming and they told me it can't fall below five PSI but they couldn't find a maximum range.
If I buy this pump is the pre setting of 15 psi okay or do I turn it up or down?
If somehow you can find a way to find my range of my PSI for my fuel this way I can feel comfortable up turn it up and down as I choose.
Thanks
Adelino
( Adelino Mercado Jr, 09/13/2018 )
We find 15 PSI to work just fine. Any extra fuel will just be sent back through the return line to the tank. ( Support )

Please correct me if the assumptions below are incorrect:
1. This is NOT intended to replace the existing electric "prime" pump but rather ensure that there is sufficient fuel supply by running at all times.
2. Other than installing this into the system and providing it with Key-on power no other modifications are required to the fuel system.
( Eric Lang, 04/06/2018 )
The UP95G lift pump does replace the existing electric "prime" pump but you don't have to remove the existing pump. There are modifications that we make to the electrical harness but other than installing the pump into the fuel system, no other modifications are required. ( Support )
Is this a "kit" or is it just the pump? My motorhome is a 04 Country Coach with a ISL 400 engine with a Caps system.

Norman,
This is the pump and harness plus some miscellaneous fittings. For most applications you will need to purchase bulk fuel line and fittings from a local hydraulic shop.

2000 Monaco Dynasty Cummins ISC 350 manufactured June 1999. Fuel and Water separator filters mounted on frame crossbeam in rear of engine compartment.
How does this pump integrate into the fuel system. Should it go between, before or after the filters.
( Ed Miller, 07/14/2016 )
Ed,
We prefer to install the pump so that it is in between the two filters. Every coach is different so installations can vary widely but that is the preferred way to do it.
