In addition to what Gorn stated, the "dead head" test does not really show how good the pump is. A good pump has both the proper pressure and volume. Choking the return line only shows the max pressure but does not give any indication of fuel volume. A weak pump may be able to build up pressure, but fail to deliver enough fuel to keep the engine happy. One of the better way to test the pump and regulator, but inconvenient to do, is to drive at WOT for around 15-20 seconds (depending on how much open road is in front of you) and see if the pressure holds while the engine is demanding maximum fuel.

 

Thanks for the insight, I like the WOT method lol. I live in a town where there are nothing but cornfields and cows so open road is not an issue. I may just be doing this test soon

 

Just make sure you are looking at the road, and not just staring at the pressure gage. lol

 

lol i planned on having a passenger for the gauge lol, dont really need to total this car. What pressure should i be looking for?

 

Also, if the regulator is the only thing that is bad what would it cause?

 

hate to be teh noobz lol but what do you mean by WOT lol. and to where do you hook the pressure gauge too

 

WOT = Wide open throttle, pedal to the metal, east bound and down, etc.....

 

^^Love this description

 

lol ok i just wanted to make sure. Last question and Ill stop hijacking the thread lol, where do you hook up aa pressure gauge

 

on the fuel rail towards the front of the upper intake, there is a cap and a valve(similar to a tire valve stem). if you turn the key to the on position it should push out fuel...mine hardly does
