Don't have any pics - maybe this will help:
pre '83: go to your local parts store and buy a generic metal 5/16" fuel filter.
Affix two wires at one end next to the inlet. If the inlet and oulet were
at right angles to the body, you would have the actual pump. I think it will work
about as well.
83-85: rotary pump - about 2/3 of the length is the motor. The last 1/3
is a little larger in diameter, and houses the actual pump impeller.
Both hoses connect somewhere on this end.
Other than that - check eBay. Sometimes they have a pic.

FPR?
I thought this would be located close to the engine, but I don't know squat about FPRs. Is it a good idea to get a new one since my motor will be requiring more fuel? Will the pressure need to be higher or lower?

Alrighty, that's what I originally took out and thought, WTF? I'll get a better look tomorrow morning. I was thinking I'm going to need to fab something to hold the Walbro in place...but I don't know what the stock fuel pump looks like yet, so I don't know if I can use the same mounting system or not. I guess I'll know more tomorrow.

The fuel pump is mounted on a plate that I think is held in with rubber vibration mounts.
The pic above looks like the vent valve - it came from way up high?
There isn't really a fuel pressure regulator on a stock 12A. Your Cosmo
engine should have the correct regulator on the fuel rail.
Keep the vent valve; you'll probably have to ditch the roll over valve.
Some guy on the "other" forum (search for "project kramer") had some
info on the GSL-SE gas tank, which I think is the same as the 85 12A
but with different in/out tubes going into it - you need to replace
this part with a GSL-SE one.

That's why I'm making a website when this is all said and done.
Can I not just get the fittings I need for this pump to hook up to what's already there?
Would it be worth it to run new fuel lines?
