Fuel pressure question set hot or cold.

Heimedw · Aug 10, 2019

On a carb engine are you to set the fuel pressure hot or cold? My fuel pressure seem to be all over the place. I want to set it for 6psi hot and I will get it where I want it. The next time I check it it's at 5.5. Then I put it back up to 6 and then come check it again and it's at 9 making no sense?

Set your fuel pressure at operating temperature and then leave it alone.

If it’s still running good when it shows 9 psi, ur gauge is probably wacko. Kim
