Hello My coach will run great for about 60 miles then loses power and just limps along spiting and sputtering and backfire out of intake. Let set for half an hour starts up and goes for another 60 or so. noticed not as much power lately. could this be fuel pump related?
I'm afraid one day it mite not start in the back country of AZ.
Thank you
is this the correct fuel pump for my coach
( Steve, 09/08/2020 )
Without having a fuel pressure gauge hooked up to see if fuel pressure drops during this occurrence, it is hard to say. The pressure needs to stay somewhere in the 60 psi range. This is the correct fuel pump for your chassis. ( Support )

Hello, I'm looking for a fuel pump and fuel lines(the braided lines that go to the pump) for a 2005 Fleetwood Bounder, W22 chassis with a 75 gal tank. ( Roger, 03/10/2020 )
The W0013952 is the correct fuel pump for your VIN and the feed/return lines that connect to the fuel pump is part # W0005111: https://www.ultrarvproducts.com/W0005111-Hose-Asm-feed-And-Return- ( Support )
Fuel pressure shows 62 psi key on. going down the road level pavement drops no further than 55 psi heavy acceleration going up a long hill pressure drops to 42 psi engine will back fire and surge. when you back off to normal acceleration fuel pressure returns to 62 psi. filter has been changed and it made no difference. this 8.1 is in a 2008 Gulf stream Sun Voyager motorhome, with 34100 miles on it. does this appear to be a fuel pump problem?
Thank you
( Jack Sexton, 12/09/2019 )
A drop in fuel pressure like that under load would suggest that the fuel pump is having a hard time keeping up with the demand. Replacement of the fuel pump will likely cure the problem. ( Support )

hello,looking for the right fuel pump for my 04 newmar mt.air workhorse chassis thanks Charlie ( CHARLIE YAMADA, 07/07/2019 )
You may have a 2004 Newmar coach but it is on a 2003 Workhorse chassis. The part# for the fuel pump that you require is 25178125: https://www.ultrarvproducts.com/25178125-Module-Assembly-Fuel-Tank-Fuel-Pump-(with-seal)-(includes-sender-unit) ( Support )
The motorhome will not start and the fuel gauge is pegged at E with a information center message " low Fuel" The generator runs and it will not draw gas out of the tank if it at or below 1/4 full, so the tank is at least 1/4 full. Is This the correct fuel pump for the above mentioned motorhome and does it include the sending unit and pressure regulator? ( Greg Rullman, 05/29/2019 )
Yes, the W0013952 is 100% the correct fuel pump for your VIN. ( Support )
Does this pump have a check valve. My rv will crank for several secounds like it has lost its prime. Just started a couple of weeks ago? ( Mike, 07/05/2018 )
Yes this pump does have an integrated check valve. Does this occur all the time or only on a restart from sitting for a short period? If you cycle the key on and off a couple times and then try to crank does it fire up or still crank for several seconds? ( Support )
I looked up this fuel pump and it is listed for a 6.0L and I have a 8.1L would this still be the correct pump. Thank you for your help ( Alex, 03/20/2018 )
Not answered yet.
Part number W0013952 looks to be the right pump, but just want to make sure. Also, does this come with the "O" ring? My lock ring was also damaged, I couldn't find them on your site, do you have these as well?
Tony Fox
( Tony Fox, 07/03/2016 )


Yes that is the correct fuel pump for your Workhorse. This does include the O-ring seal but not the lock ring. The part number for the lock ring is W8005345
