Mystery 661 fuel pump

[Andrew Mace]

Would anyone like to hazard a guess as to what a fuel pump with a tag reading "CAPAC 661R" might fit? It's a rebuilt pump, made in U.S.A., that I got years ago from someone who thought it was a Triumph car fuel pump (it's not; it's bigger and looks kinda like it might fit some American V-8).

Google didn't help me, so I throw it out to you folks! TIA!

Aluminum housing with a "double circle" lookin' set of valve protuberances on the top? Inlet and outlet on the top?

Assuming the block off plate is fuel pump specific, it would appear to be a big block chevy pump - Chevelle & others, '65-99
661R block off plate

That plate is about universal to most AC mechanical pumps, IIRC.

I saw those references to block-off plates and wondered if that might be relevant. Basically, the thing looks like a giant version of a typical Triumph Spitfire fuel pump. I'll try to get a picture tonight.

Here's a 663 pump which can't be too far off at least in technology
Ebay

That number is on my fuel pump on a 400 hp small block Chev in an old (64) El Camino.
Don't know if it is original or not.
