The install is a snap, the C4 is probably the easiest fuel pump R&R I've seen! You can take the entire assembly out through the fuel door.

Unless it has, or is, failing, the stock pump bypasses as much fuel as the engine burns, under most circumstances. Is the stock fuel pump not meeting the demand? Are you running out of fuel under high loads at high rpms? If so, a new, stock pump will probably cure the problem, unless you have built the engine where it has a very high demand. Of it is determined that you need it, the proper Walbro pump fits in the stock location. There is no need to look for a place to install it.

I've got one on my TPI Z-28, and is quiet and reliable, but I really don't NEED teh extra pressure. I was
going to put a 383 in it before I got teh Vette, so I went heavier, preparing for teh bigger motor. I'll buy
another one if and when teh OE Vette one goes...

I have attached a WORD file documenting how to remove and install a new fuel pump. Good luck.
