ojh Posted August 8, 2020 Share Posted August 8, 2020 Anybody know of a 5psi gauge? That would be a nice, handy gauge. Link to comment Share on other sites More sharing options...
W_Higgins Posted August 8, 2020 Share Posted August 8, 2020 Do you mean for use as a tester or to mount in your dash? Teens - 20's Cadillacs with pressurized fuel tanks use a dash gauge that reads 1-4 psi. Link to comment Share on other sites More sharing options...

Very Nice! They had fuel lines going to it? or did they have a sending unit and it was electric? Link to comment Share on other sites More sharing options...

Very Nice! They had fuel lines going to it? or did they have a sending unit and it was electric? Well, technically it's an air pressure gauge. The tank is pressurized with a couple of pounds of air. 1 Link to comment Share on other sites More sharing options...
1912Staver Posted August 8, 2020 Share Posted August 8, 2020 They connect to the top of the tank and only read air pressure. Lots of vehicles used air pressurized tanks in the early days and many versions of gas pressure gauges exist. Most of the early ones are standard size round gauges. Usually marked either Gas or Air.

C Carl Posted August 8, 2020 Share Posted August 8, 2020 Right. To start, use the hand pump to 1+ psi, then the small engine driven compressor takes over upon starting. - Carl Link to comment Share on other sites More sharing options...
wayne sheldon Posted August 9, 2020 Share Posted August 9, 2020 If you look at the picture under my name (currently?), you can see the dash from the '24 model T coupe I used to have (really miss that car!). The car was from the hills of San Francisco, and had an after-market hand pump to pressurize the fuel tank, and a five pound gasoline (air) pressure gauge to monitor the pressure. If I ever get another car running and drivable, I will change the picture (so someone reading this in the future may know why?). Link to comment Share on other sites More sharing options...
C Carl Posted August 9, 2020 Share Posted August 9, 2020 Oh Wayne ! Put that way, I sincerely hope you get to change that picture soon. You really must get behind the wheel of your own car before the sands of time sift much further to your disadvantage. I don't know how long you have been "stuck in the garage", but as one who has been there myself, I know the tears of joy shed when, after years, one is finally on the road again. Well, I have not driven the '24 since March. Been WAY too occupied. I think I will take this as a butt kick to lube the valves and fire it up this week. Man, I sure hope good fortune shines your way soon, my friend. - Carl Link to comment Share on other sites More sharing options...
hidden_hunter Posted August 9, 2020 Share Posted August 9, 2020 Occasionally on fleabay the earlier type 61 gauge shows up which has amps, fuel and oil - they're all individual pieces that you could separate the fuel one on The book says you need 1lbs to start, I don't find I need anywhere near that to get it to start (maybe 1/2 lbs) and the regulator once it was all cleaned maintains the pressure flawlessly Link to comment Share on other sites More sharing options...

Mark Shaw Posted August 9, 2020 Share Posted August 9, 2020 (edited) Early Buicks that have a threaded hole in the exhaust manifold that can be used to pressurize the gas tank. My 1913 Model 31 Buick has this modification (with a an inline spark arrestor) that has performed perfectly with no moving parts for many years. The back pressure from the muffler provides the perfect pressure to keep fuel supplied to the carb for those long uphill runs....

1912Staver Posted August 9, 2020 Share Posted August 9, 2020 If the original poster is looking for a fuel pressure gauge for a conventional , non air pressurised system. Any car with a fuel pump, either mechanical or electric. Then it is an important safety rule of thumb to not run a capillary tube up to a dash mounted, direct reading gauge. Us an isolator; usually a diaphragm type, or a electric sending unit near the engine and mount a electric pressure gauge in the dash. Oil in the passenger compartment is risky enough { messy and potential for burns }, but gasoline can be deadly. Greg. Link to comment Share on other sites More sharing options...
