Fuel Pump Removal/Install?
Well I guess im just wondering if the fuel pump removal and install is hard on a c5? also witch one to go with that can hold up to atleast 625hp. Every time I get n to the car I have to keep turning the key back and forth before the fuel pump will kick on and just the last time it took every bit of 20-30 mins to get it to start, I just don't want tobe going down the road and it go out Please Help Thanks

What year is your z? Only the early models I think 2002 and earlier have an easy access fuel tank from the drivers rear wheel well. The best upgrade for that power goal is the LPE pump and racetronix harness (either from lingenfelter or racetronix themselves).
That kit is good for 600whp with the pump alone and more with the harness upgrade. I think around 700whp.

I have the LPE pump and harness with BAP, and although I do run Meth, it looks like it is going to support around 800rwhp without dropping much pressure.
My pump (98) was simple, but not sure about the newer ones.

Sure it is not the starter? I had same issue, replaced starter, fixed.
I did the pump too for my SC, not bad, but aggravating working in confined space tying to put pump back in, and not bind up float lever.

The earlier C5s, like your '99 (and mine) use a completely round gasket, plus the mounting bolts that come with it are of the "breakaway-head" design, as opposed to the later C5 pumps that come with a "Double D" gasket (flat on two sides) and non-breakaway bolts.
1997 to 1999:
Here's the gasket that SHOULD have come with yours, as shown above. Notice the breakaway-head bolts.

At first blush Robert, that sounds like you received the wrong part number from the get-go.

yep....I ordered it right from LPE and it was supposedly the correct part....everything else is spot on....so maybe I got the wrong part in the right box
oh well....it all worked out but thanks for posting pics of what I described

Shop here, or at any of several Racetronix distributors like Texas Speed, Lingenfelter or Tick Perfomance. You want the RFPK-007 kit:

Note: If you're going much higher HP, I recommend contacting Lonnie's Performance for one of his dual, in-tank pumps.
