Then and Now Automotive

No Pete those are all gravity fed. I actually found them when I was looking to rebuild the Holman Moody pump. I knew it fit and I liked the oem canister filter on it. Glad they worked out for you.

Me too!
They're quick, communicative, very helpful.

I've had them do several fuel pumps, the last for a 312 Interceptor.
They bench test them and confirm correct pump output.

Maybe it's not in the picture or I don't see it, but it looks like you're missing the pulsator diaphragm in that collection of parts Pete.

Maybe you model doesn't use/need one for whatever reason like maybe the big filter bowl on the bottom makes it unnecessary but I doubt it.

Pete, we don't have a fuel pump like that on our Y block. PO replaced it with an automotive pump, but we do have one on our 100 hp Interceptor. It works well, buy looks pretty dangerous with that glass bowl,

Then and Now got the correct kit out. Yes, they know the hard water is coming!

There's the pulsation gasket and yes, the big spring.

KENO wrote: Hate to keep asking silly questions Pete but it looks like they're making your life difficult having to assemble the big spring and upper seal onto the shaft of the diaphragm. Maybe a 64 Carter pump is different from one from the late 70's as far as the diaphragm, but the later ones come with the spring and upper seal already assembled onto the shaft and no way to take it off or replace it It looks like yours must get assembled and have a removable retainer of some kind at the top

Ken,
Yes, the diaphragm assembly from them comes unassembled. There's even a note in the instructions that came with this kit regarding the assembly. Then and Now makes up the assembly with a different diaphragm rod seal that they say is an improvement over the original AC/Carter design. The assembly is stacked, compressed into the pump body and then retained with the pump arm. With only two hands, a vice and C clamps are needed. The only other minor hurtle with this pump is the removal of the arm pivot pin since it's in a blind hole. A small hole is needed to be drilled on the blind side so a punch can drive the pin out. Then after reassembly, some good old JB weld is used to plug the drilled hole.

Sorry but no pictures of the rebuild. As Gary has mentioned, my Instamatic is at Photomat getting the file developed. .

I tried the needle nose but with the shape of the arm on this pump it didn't work. The Then and Now instructions actually mention drilling the hole.
