Fuel pressure question - HELP!

You won't believe this. I contacted the Aeromotive tech dep't yesterday as they are the manufacturers of the Cartech line of fuel systems. They said that there is no check valve in these systems as they aren't designed for street use. They also said the regulator wasn't designed to maintain pressure. I had him listen to the pump itself (which he said is upposed to run loud)and we walked through doing a vac test on the car (which ended fluctuating at 10-12 inches....is this bad or good?) and he asked me what type of pressure gauge I had. I told him it was a liquid filled Jegs mech gauge and he started chuckling.

HE explained to me how he's been receiving at least 12 calls weekly on these gauges. He asked me to put a hair dryer to the gauge and you won't believe what I found! I had the car running and I cranked the dryer on the gauge and the f%&^ing pressure dropped to 30 psi!! I then took a bad of ice and placed in around the gauge and it increased to 40 psi!! Can you believe it!?? I paid like 40 bucks for this shitty gauge and it almost cost me a 1000.00 fuel system, as I was considering purchasing a new system. I guess maybe that's why she wasn't leaning out.....makes sense now. The pressure is maintaining but it's the blasted gauge that's at fault. What do you think?? I think I found the problem.

Figures. Well, since you drive it on the street, you might want to replace the regulator. I've never heard of one that doesn't maintain pressure, but if that's what the guy says, then I guess it must be. For a daily driver, you want it to maintain pressure.

Take care,
