I read a few write ups and it seems like one of these will work with little modification. I m not trying to be a cheap ***, but $340 for a delphi pump is ridiculously overpriced.

Are there any ill effects of putting a performance pump in a stock truck? Will it overrun the fuel pressure regulator? Etc...

If you have any questions about my application let me know. It is a bone stock 5.3L, 2000 Z71 Extended cab.

 

You will be fine with a bigger pump like the walbro.

 

Awesome thanks man!

The $150 Racetronix pump is a drop in affair correct?

 

Bueller?

Here are some pictures of my pump assembly. For some reason my OEM pump does not have the nipple on it for a venturi style? What do I do in this case?

Leave the nipple open and let it ride?
