I decided to check my valve clearances today to hopefully reduce the sewing machine noise in my l20b. Once I got the camcover off and started turning the motor over I noticed the fuel pump arm wasn't riding on the fuel pump eccentric, it was loose, so the arm could move left and right, and it did just that, wearing a chunk of metal out of the front of my cam gear, will be switchin to an electric tommorow. I am sure it was recently swapped out for an aftermarket one but there are no receipts to be found in the pile o'maintenance records :( Has anyone ran an electric on these before, if so anything I should look for in particular and should i use a fuel pressure regulator?

It's usually minimal fuss.

FYI, the block-off plate for a big block Chevy fits right onto an L-series head. :tu:

Depends on the pump, carbs, engine, etc.

Assuming stock-ish L20b and 2-barrel carb, if you use the low pressure Holley/Facet pump you won't need a regulator.

FYI, these types of pumps work better as "pushers" than "pullers", so try to mount it low at the rear of the car.
