What to use for a pressure gauge?

Post by schwabd1 » Wed Jul 07, 2021 4:00 pm

I'm working on a speedster and want to use a pressurized fuel system with a hand pump. Where can I get a pressure gauge that will read that low? I'm guessing I want something that reads 0-5 lbs. What should the pressure be on a sealed unit? 1-2 lbs?

Couple of old discussions : around 3lbs - sun may increase pressure and don't forget the stock cap is vented

This may be an interesting attachment to include 1-5 psi fuel pressure regulator

1-2 lbs is good for a hand pump. They make modern low fuel pressure guages. The old vintage ones can get pretty steep in price.

Look at ATV tire gages on Amazon and places like Dennis Kirk. Typically brass with 0-10 or 0-15 psi scales.

"Never been there; done that", but could an oil pressure gauge that was calibrated low, work? The Dodges from the 1920's used a low calibrated oil pressure gauge.

Grainger has one that is 0 - 5PSI ( item # 18C790) but it's $35.
