Are any of you familiar with this kit? If so, any good or bad things about it?

After hearing how mclellan83 was treated by holley, I'll never buy anything from them again that's more complicated than a mechanical 4bbl carb....

I have not used that kit, but did use the Holley drop in pump & sending unit assembly. Works great and if you're not going turbo or supercharged, I would definitely recommend it!

Are you converting to EFI or staying with carb? This kit is for EFI conversion. The regulator is 15 to 60 psi which is too much for a carburetor. The rest of the kit looks like basic bones of the Sniper Fuel supply kit which is only about $300.

That looks more like a universal kit for just about any car... labeling it to capitalise specifically for g-body is pretty low and for that price just because they did the leg work you in parts, no thanks.

Looking through the instructions and part list, it looks like a fairly complete and thought out kit. Unless you need a larger pump for a specific application, you could probably use it for most EFI setups. You might be able to swap to a different regulator to use it for a carb setup too.

They also have a version, 526-23, that has the GM style filter/regulator if you prefer that.

It’s a lot that includes most everything you need. You can accomplish the same thing much cheaper, $200-250, but you have to modify what you have and source individual parts.

Whatever floats your boat.

Yes I'm running an L99 from a 2014 Camaro SS

Don't know much about fuel systems, can you explain to me the difference between return and return less? And pros and cons of each
