Went out to spend my 15 min. on the gasser, which turned into a couple hours. The electric fuel pump had a small leak from the end plate so I removed it to see what was up. The seal looks like a flat rubber seaal with an O ring built into it, and it doesn't seal well.
I got out the rubberized gasket material and clamped it to the end plate, then cut it to match and drilled the holes. After that I put some ultra black RTV on the gasket and seal, and bolted it back on. Seems to be holding now, and stopped the leak.
