I purchased this pump 25178145 for my 99 P32. After replacement it runs for about 1.5-2 hours then it won’t have much power. Fuel pressure is steady at 45 psi which I think is too low. Should be 58-62 from what I have researched. I’ve replaced fuel pump, brand new fuel filter, spark plugs and wires. No check engine lights on dash. Do you think it could be fuel pressure regulator? ( Jay Benjamin, 05/22/2023 )
Yes, there is a good chance that your fuel pressure regulator is leaking. Pressure should be at least in the mid-50's. ( Support )

Hi Penni,

    Based on the VIN, the fuel filter is W0013351 http://www.workhorseparts.com/W0013351-Standard-In-Out-Fuel-Filter and the fuel pump part# would be 25178145 https://www.workhorseparts.com/25178145-Fuel-Pump-Assembly there is no filter in the tank for that VIN they only used to use a "Sock" on the fuel pump that is no longer used. I do not have the dimensions of the is pump available to me. However I can tell you it is listed as the correct one for your VIN.  Hope that helps!

I am trying to figure out if I perhaps need a larger rated pump for a FiTech fuel injection system I recently installed on my RV. The part # of the one I have installed is GM part # 25178145, which I see you offer. Would you have the pressure and lph this pump is designed for? If I were needing a pump requiring 90 psi and 255 lph, what would you recommend?

( Greg Schneider, 07/13/2020 )
The 25178145 is designed for an 80 gallon fuel tank and for ~60 psi pressure. I was unable to find any information regarding what the LPH and maximum pressure limits are of this pump and do not know of a higher performance pump that would match this same style pump. ( Support )
