Anybody know who might produce a fuel pressure gauge with a lower limit? I have a 15 psi gauge with my 97's, running 2.5 pressure and can't get the gauge to to move off zero. I tried a couple different models with the same result. I'm thinking a 0-5 psi gauge might do it. Thanks, Jim M
So, did you ever find a fuel pressure gauge with a lower range? I'm looking for something as well. BTTT
I get all my pressure gauges from Marshall, in my opinion the best in the industry and they start at 0-15, nothing lower. A good gauge would read accurately maybe your pressure is to low to register, eh?
Last I fired the motor up it was right at 2.0 or 2.25 psi, or so. I've never seen a 0-5 and the only 0-10 gauges I've seen are BIG money. But for myself, personally, I can live with the 0-15 as long as everything is working right, but was thinking a 0-5 would make more sense, since it will never be out of that range, if one existed. Guessing not...
A lot of low pressure stuff is measured in inches of water. Maybe see what's available in an in/h2o gauge? Used on natural gas, ....
You likely will need to look for industrial gauges instead of ones directed towards the automotive market. Might have to remote mount it in a hidden place if you don't like the look, but you shouldn't have much trouble finding a 0-3psi or 0-5psi gauge.
old chevy and dodge (and probably other) oil pressure gauges were 1-5 psi for a period of time, but they are generally expensive online. you could look for these at flea markets. a company called "national" also made very nice looking 1-5 psi fuel pressure gauges back in the 20s(?), also expensive. modern low pressure gauges do exist, but make sure they are rated for gasoline before you buy one.
Someone told me that oil-filled ones don't work well at low pressures they said drill a small hole and let the fluid out and they will work fine. Don't know for sure ,but someone told me one time???
Go on line and look in the Grainger catalog. They have inexpensive low pressure gauges. Using a liquid filled gauge will dampen the needles action and the gauge will last longer. But in the cold weather the glycerin becomes stiff and the actual pressure won't be accurate until the gauge warms up. The alternative is to use a snubber in the line to a regular gauge. The snubber has a sintered metal disc inside the and dampens the action. Grainger should have them also. By the way, it takes 27.1 inches of water to equal 1 pound of pressure.
I found an old fuel pressure gauge at a swap meet last week stewart warner 1 to 10 lb, the number on the side is 2319F1,haven't checked it out yet.4 bucks I figured I couldn't go wrong.
I run a holly blue pump from the tank to a holly 4.5-9 psi reg. set @ 5psi. mounted on the frame in the same area where the stock sbc mechanical pump should be, from tha reg up to a low pressure holly reg set @ 2.5 psi, from it about 6" to a 6 outlet fuel block, 6 fuellines from it to the 6 97s.
Okay, I know this is an old thread but I also would like to have a 0-5 psi fuel pressure gauge. Given what you posted here at the time Dick, what’s the story on this picture that has popped up recently in another thread?
I emptied the glycerin out of mu gauge and now it works. You might also try replacing the glycerin with DOT 4 brake fluid or Dot 5.
That is easy peasy, my friend. Just message me and I will give you my PayPal addy and we will get this thing going.
I’ll do that Dick. So I take it you’re still selling the 0-5 gauge like in the picture but it’s not on your website. I’ll send you a message, I’ll order a coil cover too. Thanks, Larry
Sent you a reply to your email with a couple of other items, if you can figure shipping and send me a PayPal invoice that will be great. Thanks Dick Top notch service as usual Larry
Have you tried here https://www.surpluscenter.com/Gauge.../?page_no=1&fq=ATR_Range:Up\+to\+15\+PSI\+Max cheap and easy to read!
Got my order in with Dick for that neat 0-5 psi gauge and one of his coil covers too. Thanks again Dick
