fuel pressure? ok , i have the GWP/ATI procharger kit,so i have the areomotive inline pump and i also just installed a new intank walbro 225 a few weeks ago.
i had this problem before the walbro where the fule pressure would drop at high rpm and cause detonation.
i checked the areomotive pump ( comes in at 0 vaccume)and it's working fine.
skip a few weeks to the present, now i have the walbro in and when driving around my fule pressure is 50 psi and it drops to 40 psi at part theottle anywhere before 0 vacuume.
and recently i notced that the car wouldn't start up right away, and when i turn the key in the ign. on position , the fule pressure doesn't build up to quick, and goes back to 0 as soon as the pump stops priming ( as opposed to before when the pressure would drop from 60 psi to 50)
what is going wrong??
is it a fule regulator issue??

Re: fuel pressure? just out of curiousity (sp?) , are there two different kinds of fule pumps??
cause it seems to me from people i talked to that they seem either describe the type i have ( pump sits in bucket kinda encolsure), or another kind that resembles the traditional pick up tube assembly.
