Message	Went to AutoZone and got an el-cheapo oil pressure guage that goes to 120psi, marked in 5psi increments. I T'd into the fuel line just after the filter to check my fuel pressure. At low RPM, 15psi I'm only getting 55psi and as the RPM increases, the pressure falls back off to 45psi! Ahhh! Not sure what it is at this point, I'm still running the NA pump. Could be that or the FPR, although the FPR only has 70K miles on it. Suggestions? [ ashleypowers.com ] [ agpowers@bellsouth.net ] When pigs dance, you better get it on video...
