2-Ton;

I've gotten some parts from EBay a few times and even went to NAPA and asked the Guy to look in his Old catalog stash as opposed to the computer. I've had several "New" pumps fail because I guess they were too old stock and the diaphragms would break.

Is the old one rebuild-able?

So in the end, I went with a Carter electric and no more problems.

*PUMP LOCATION-I think some one mentioned the fuel pump is located on the top front of the engine mounted up with the arm pointing down looks like.

Thanks Funk
I did the same thing.
NAPA pulled the old hard copy out and showed me where it was discontinued years ago. Thought about taking the arm off and putting it on another pump.
But went with an electric pump.
The old pump is not rebuildable.

And yes, it is mounted on the front, top center of the engine with the 12 inch arm vertical.

Story of the truck here.

I'm the one who has the running 637 on youtube. The pump you see on the engine is actually for a v6. I simply changed the arm like Two Ton suggested. I do have a couple of those pumps now if someone needs one. Not sure how long they sat on the shelf though.

I believe I put your video on the boards over at Heavy Haulers on the '67-'72 Chevy truck site. We have some 637 fans over there as well.

I'm also the one that used to drive a 637 V-8 Gas in a GMC J-9500. It was a '71 model with the very rare combo of a 10-Speed Road Ranger behind it.

I've never driven anything with a 637. I need to get this one I have into something. I'm going to try and get a HEI from a Buick 340 on it. I got some extra adapters from We7x.

You would need an HEI from a Buick 350, the 340 was long discontinued by the time the HEI was introduced.

You're probably right. I got one on Ebay that fits them all the way back to the 215. It was probably for a 350.
