About fass ddrp replacement pump
 

hello i was wondering my truck came with a fass ddrp replacement pump and i was wondering if on these pumps if you can adjust the fuel psi it puts out ? And wondering if it would be good enough for a edge comp box to keep good fuel pressure.

these are marginal for a completely stock truck, even the best ddrp's. and i have seen several brand new ddrp's weak out of the box, in fact pulling down to 2psi @ wot on a stock truck.

no way to adj fp. and even if you have a good ddrp you will be low fp running a comp.

step up to the better fass imo

thank you.

I agree you need more fuel than it will give

Thank you.

go with air dogg same set up as fass same waranty just cheaper

Can't go wrong with either the FASS or Airdog. Both are great units and both have there pros and cons.

what about the raptor 150.s

i have the raptor 150 its awsomew and quiet and only took like 30-40 min to install

i have the money for a airdog 150 but i dont know what is a better deal getting the raptor for 400 or the airdog 150 for 500.
