does anyone run a mechanical oil pressure gauge? My sender seems to be having some issues. And i can pick up a mechanical op gauge pretty cheap, alot cheaper than an electric gauge. . plus i should be getting my rebuild back soon and would really like to be able to see oil pressure. thanks

Yes, I do. Get yourself a 4' long nitrous oxide -4AN stainless-steel braided hose kit and run it from the back of the engine, where the stock sender rests, all the way to your gauge on the a-pillar.

I do. You don't need AN line, most gauges come with flexible copper tubing, or are sold along with copper tubing kits for an additional ~$5. Mine is tapped into one of the ports on my FC3S.org oil pedistal.

 

I run one too, yeah you can pick one up for about $50 and should come with an install kit. I located mine under the radio in a blank panel I made and ran the light wire to the glove box light and tapped in there so when the lights are on- so is the guage. It's reassuring having one.

 

I'm beginning to be a firm believer in mechanical gauges. It seems many electrical gauges, even aftermarket, are just not up to par. Why have gauges if you have to question their accuracy all the time?

Get a sunpro adaptor kit at autozone, its like 5 bucks. In it should be a 1/8-28 BSP to 1/8-27 NPT adaptor, which is necessary to fit into the block. Then use the line and fitting from the oil pressure gauge and run it on inside the car from there. IF you're paranoid, run a copper line or stainless line. I've run the included nylon line for years with out any problems though.

 

I trust my aftermarket electric gauges. They are very accurate and I dont have to worry about a line bursting having fluid all over the engine bay or in the cabin. It's not very likely that will happen but it eases my mind more.

 

ALSO: They do make fluid isolaters so you can run mechanical gauges (including fuel pressure) in the cabin. They do it using a fluid isolater at the firewall. Basicaly the fluid pushes up against a diaphram which has gear lube, hydralic fluid, or whatever on the opposite side. Then you're running the gear lube, hydralic fluid, or whatever in the cabin instead of fuel or oil.

Is this good, yeah? No incabin fire from fuel gauges leaks, and no "add oil" light from finding your passenger side floor looking like a tarpit.
