Will this fuel system work for my ZZ502 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've got a ZZ502 and I want to have a fuel system that will comfortably handle the needs of the motor in its stock form and possibly have some room to grow.

Here is what I have in picked out so far.

Fuel Pump - Holley 12-815-1

Fuel Pressure Regulator - Holley 12-843

Safety Switch - Holley 12-810

Pre-Pump Filter - Holley 162-553

Post-Pump Filter - Holley 162-563

I think this setup will handle my needs but, this is the first tank to carb fuel system that I've setup.

Does anyone have any issues or any better suggestions?

That looks like a very solid kit you put together. It will be more than enough to feed the big 502. If you are looking at adding nitrous or forced induction, check out the holley billet dominator series pumps. I take it that the 502 does not have a mechanical pump option?

It's way overkill for the ZZ,, but is one of the few Holley pumps that is hard anodized to tolerate the ethanol in todays pump gas,, so tha and 'room to grow'... good choice. It's not quite as noisy as some of Holley's other street pumps. Depending on what carb you put on top of it,,, you'll want a GOOD fuel pressure gauge (Stay away from that Autometer isolated fuel pressure JUNK,, it's anything but accurate)
