Where can I have fuel pumps tested?

[phunny]

I'm wanting 3 pumps tested to see exactly where they stand vs what they claim. I've also seen a lot of people asking about what fuel system and handle what power and there seems to be a huge gap in what will and will not work.

Are you questioning what they flow? Im not sure if your going to find a place to test them, to compare them, what are your concerns for your goals? Do you doubt what is being claimed, which ones are you trying to compare.

I'm more wondering if I have a failing or failed pump.

Have you checked your fuel relay?

I'm getting fuel and the car is fine but it seems as though many think that I should be seeing more flow than I am. It's possible though very unlikely that my inline pump has failed and my 450 is doing all the work.

Why can't you just put a power and ground source to the pump and check your fuel pressure gauge on your FPR? (if you have one). Also, if you can mount a gauge outside the car and monitor it while under boost. FIC (fuel injector clinic) should have the means to test the pump if that would be your last resort...

Charlie... Have you tried bypassing the inline pump and seeing if your pressure drops and/or flow increases? That would be an easy down and dirty test I think.

What type of filter are you running, and what is it's condition?

You could also pull the line at the return, and time the flow into a 5 gallon bucket. By injecting air at the AFPR, you can test it at different pressures and compare the results to what you should be flowing at the supplied pump(s) voltage.

Speaking of voltage, have you measured it at the pumps to make sure it remains constant at a decent level?

This is the way we used to do it. I'll ask my friend what the formula was (of course it is probably online somewhere) and post it up if the OP needs it but pretty much measure the flow into a container. You really do nit even have to measure the tine it takes to fill something, you could also go by a volume over given time test (ie: 400 lph pump running with no restrictions should flow 6.667 liters in a minute) to get an idea. All you need are the rated flow and pressure numbers of the pump, a container, good gauge, and a calculator to figure it out.
