Questions: my old fuel pump looked like it was not pumping enough fuel into glass bowl. orderd new one and still seems to only pull approx. 1/4 inch of gas on floor of bowl. runs but rough . 1946 l head 134 . any thoughts
Question By: peter rania on Jul 26 2022 5:21 PM
That is a common misconception that the bowl fills completely with gas. Most times 1/4" is about the max that it will get filled. Thanks

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 email@example.com too.
Answer By: Willys Jeep Parts Tech on Mar 18 2020 5:45 AM

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.
