Testing for Fuel
Okay, I'm pretty sure my car is still not getting enough fuel. I've replaced the injectors (one was cracked pretty bad and the others were probably clogged) and the rubber fuel lines, it's a little better but not much.
My next plan is to replace the fuel pump and the fuel filter (I'll have to order both and figure they'll get here around the same time). I'm thinking of getting some kind of fuel pressure guage and this leads me to my question.
Anyone know off hand what the fuel pressure should be?
Does anyone know of an easier way to make sure you're getting the correct amount of fuel?

Looks like the S5 pump pressure (Jumper/ign on for 10 sec) 64-85.3PSI. Shut key off and wait 5 min. >18PSI-Remove hose from filter and connect to pressure gauge directly. When gauge in line pressure should be 34.1-39.8 (Pressure Regulator controlled).

Just looking through some information and looks like the hold pressure shouldn't drop below 57lbs after 5 min. NOT the 18 lbs listed.
Trying to get the info off the 'net while at work. Tough to do.
