2nd Gen Non-Engine/Transmission FASS DDRP better than stock pump?

[GreggNoble]

i was about to buy a fass DDRP when i did a search here and read that some guys are not getting any beter performance than the stock pump! they were getiing good pressure at idle, but when reving the pressure weren`t good at all! Any commens before i buy? i`ll be putiing the ddrp on my 01 automatic(engine near stock) has" banks power elbo "with 4" exhast and the "banks high ram intake. "

I've installed several DDRPs. One worked perfectly. The other 2 have been plagued with issues. I personally don't think they deliver the additional flow claimed. Also, the fuel pressure seems to vary greatly from day to day and pump to pump.

 

[GreggNoble]

well, thanks. is there another pump in that price range that you would recomend for mild modifications to the cummins?

I think BD makes a better stock replacement pump. I cannot find my book, but thought there was something from Genos Garage.

Geno's has several FASS pumps they mite have a BD also.

I have had good luck with my FASS HPFP 95. Have had it on for two years with no issues. I run 16PSI at idle 13PSI WOT with 32ft RV.

Ive been disappinted with mine, 15psi at idle but will go down to 6psi on A hard pull. Todd

when you guys speak of pump pressure do you mean after the filter? cause i got a new stock carter pump on mine and i only got apx 6. 5 lbs at idle. filter is new also!

I am reading mine at the inlet to the VP44

[GreggNoble]

Yea, i guess its the only true measurement of what the vp44 really gets!
