Seeking some guidance on obtaining the proper fuel pump for a '70 L78. Apparently, Ground Up offers a new reproduction GM 3/8" w/o return line pump. Has anyone had any experience with these pumps (quality & performance)? My preference is to source an original rebuilt unit. Can anyone recommend the best resource for this item.
Thanks in advance

Very tough to find and even tougher to find one that will still works with a correct date code. I think the part number is 7040727. 40727 will be stamped on the side mounting block. There will be a date code there too. I hear there are a few that actually rebuild them, if you happen to find a correct one for your application. I think this person rebuilds them or used to. He might have one for you ready to go. I don't know. I believe his first name is Jeff....

Here's the link....

Good luck. It takes time to find some of these parts, as you probably are aware.

Regards,

I'm currently running the reproduction mechanical Pump from Ground up. I believe the differance is the originals say "AC" embossed on the housing.

It's keeping up with a 500HP 454 pretty well, so I'd give it the thumbs up.

On some of these parts, you just have to draw a line in the sand and use reproduction.

Either that or drive a $100,000 Base Model Chevelle.
