Percolation? Heat soak? Don't drive during summer??

I looked for a little fuel guage to Put in the edelbrock carb line, but they didnt have one there. Maybe I'll order one from jegs, its only like 20 bucks...
Dont bother with the Jeg or Summit gauge their china junk and dont read when they get hot.
You mentioned that you have a Vacuum/fuel gauge, that's what you want to use just need to get a barred fitting that will tee into your fuel line. That's what I have been using for decades.
