Iv bin having problems with my stang, It's got no power after it warms up and if i try to rev it with a little pedal pressures it stumbles but if i floor it it's ok, it also has trouble starting if its hot i have to turn the key and give it gas and then she fires up. also when im looking at my fuel pressure gauge it jumps all over and if i rev it the pressure goes down. could this be a bad fuel pump or injectors it does not wine or anything like that.

check your fuel filter... thats what happened to mine when it was clogged....

Also my pump is going out and from most people I have heard from, it will either get really loud, really quiet, or it will moan. Mine is moaning it used to have a high pitch to it, now it has a low drone... a Walbro 190 is going in this week though...

does any one recommend a brand
Well most pumps out there are usually made by Walbro then repackaged for other companies and sold as their own like BBK, aeromotive(?), I think even ford motorsport is a Walbro

Anywho The best prices I have found so far have been here www.jdsperformance.com
