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.
( 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.

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. ( Support )
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 )
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. ( Support )
