Questions: my fuel pump & line is retaining too much pressure after shutoff, so that the carb leaks fuel into the intake with the engine off. does this spacer lower the fuel psi and resolve this issue?
Question By: erick on Mar 17 2020 8:08 PM
Its more likely that your motor is dieseling after shut off. I would double check your timing. You can email mike@kaiserwillys.com too.

Questions: How thick are these spacer? My fuel pump works but it seems to take a long time to fill the glass bowl up when its been sitting for a while. I wasn't sure if adding this part would make a difference, if its only like 1/16 thick, could I just get some thicker cork gasket?
Question By: Ryan S on Jul 21 2016 10:41 PM
It is approx. 1/4" thick.
