Need a fuel pressure gauge

Bad idea to bring fuel into the cab.

Easy enough to get a fuel pressure isolator to install on the engine side.

If all the OP is wanting is a "test gauge" then I'd talk to the local hydraulic hose shop, and have them make me one up.

 

Roadking 58,
what is the model number of the Stewart Warner gauge and where can i pick up one. I have a BXS and the fuel pressure is between 105-120psi, so i need a unit that can handle that kind of a range.
Thanks!

 

For a simple test gauge, get a compucheck fitting and make one up, or you can buy one for around $120.00. C15's have the test port on the filter base. Or do like others have said and mount it on the frame somewhere.

For a dash mounted gauge an isolator or electronic gauge is the only way to go (no fuel in the cab). My opinion, an electronic gauge would be easier. You'd have to mount the sendor, which would require an adapter fitting, then some basic wiring. Autometer makes decent isolators if you prefer a mechanical gauge.

 

go to Tel-Tek out of Sparks, NV, they have them. I have several of their gauges with no issues

 

o my cabover with big cam i tried a cheap electric gauge from local parts shop but found it inaccurate even though it was a 0-300 i decided to go with a autometer phantom a little expensive but that one has been working really good.

 

got mine off ebay or u can google it, called Glowshift, 100 psi and has a electronic sending unit no fuel in cab. in dash mount standard hole size. 60 bucks or so. had it for over a yr great quality.

 

i'll second that! had a friend put one in his dash once. 3 months later the gauge went bad. leaked fuel all over the underside of dash and wires. soaked the carpet. he couldn't pull off the road fast enough and shut it down with fuel squirting out under a 100lbs of pressure. electric gauges are ok but not that accurate. I have a liquid filled gauge mounted on the fire wall, yes I have to have the hood up to look at it. or I can stick it up through the gap between the hood and windshield to look at it. after my friend replaced his carpet and cleaned all the fuel that he could, you still get hit with the fuel smell when you open the door!!

 

We put a OEM mechanical gauge in my 379 back in 2000. Still have it in there with no leaks in sight. It would suck if it leaked like your friends though. My truck had a 3406E in it originally but now has a mbn C-15. I'm not sure why the engine type would affect gauge life?

 

I know this is kind of an old thread but I see a couple of you put actually plummed in a gauge.. do you remember what size fitting you used in the filter head. Just trying to round stuff up do I can make as fee trips as possible to the parts store.

 

Well, because I am unsure, but isn't the in-dash fuel pressure gauge on the 379 liquid filled? Mine is out also and when I pulled the cluster panel, there is a 1/4 inch plastic line plumbed via quick disconnect right into the gauge. I did not release the line assuming I'd get fuel everywhere. There is a small braided hose that runs from the outside firewall to the block or filter housing. I believe this may feed the gauge. There is a Stewart Warner 82325 that appears as if it will fit perfect. Plus, it measures the pressure up to 200psi. Haven't purchased it yet because I haven't found an illustration of the rear port.
