mechanical oil pressure guage install

[fordboi415]

So I just purchased a mecanical oil pressure guage from autometer but I haven't the slightest idea of how I'm supposed to install it, all I know is I have to run a copper tube from the blocks oil supply but where from???? Help me please

check that out. you just need to replace or put a "T" connector on the stem that comes out of the stock sender location. on my 2.9 it on the driverside near the power steering pump at the bottom of the engine. i just took my stock sender off and screwed the brass fittings with the copper tube into the sender.

but I haven't the slightest idea of how I'm supposed to install it,

Didn't it come with instructions? "T" off existing sender, only use Permatex High Performace Thread Sealant or you will be sorry. I'd look for single pillar mount for gauge.

only use Permatex High Performace Thread Sealant or you will be sorry.

why? i used regular old teflon tape on mine 5 years ago and it doesnt leak.

the oil pressure fitting is behind the passanger side head, near the firewall. remove the stock sender, install a 1/4" NPT "T", and screw the stock sender into one side and the aftermarket sender into the other.

Teflon tape not a good idea; if fitting is removed tape strands are hard to clean out and can get into oil passages. It does seal ok though if made for oil.

yeah i just oredered it and i havent gotten it yet i am just preparing lmao, anybody have pics of where the tubing is ran?

I don't use teflon tape on anything engine oil related. Thread sealed on the top half of the threads is best. I have found teflon tape in oil filters before.
My old antique '87 is a stick so, I ran my line through the grommet for the auto tv cable. works perfectly. I'm sorry but, I don't know about your app.

im not sure how much teflon youd have to use in order for it to get into the filter, but i use two wraps and no more. NPT is a taper-seal thread, the teflon is only there to prevent seepage, not to seal the joint. it doesnt take much to do its job. ive never had any problems with removing the teflon after removing a fitting. its a lot easier to clean up than any kind of liquid sealer.


heres the sender location:

heres my T with the factory sender (hidden behind the head) and mechanical sender. just run the tubing through the engine compartment and into one of the several through-firewall grommits.

You guys are crazy, running pressurized hot oil into your cabs...!!!

Not the greastest idea in my mind, but if you do it make sure that line rubs on nothing, also running it inside a length of fuel or vacuum line wouldn't be a bad idea.

I would hate to hear the story of how one day that line blows and burns the hell out of your sweetie's cute little legs...

ive had my oil pressure gauge for 5 years now. my dad has one in his bronco thats been there for 17 years. back in the day, mechanical oil pressure gauges came standard. they are extremely reliable and ive heard of virtually no failures that caused oil to leak that werent preventable with proper line routing.

on a properly sealed gauge, oil rarely reaches the cab. i have a few little bubbles of oil in mine, but mostly air. there is no heat transfered up the line.

60 PSI is nothing to contain. the crush fittings and nylon (or copper, if you choose) tubing is the same stuff used in compressed air systems of excess of 150 PSI. semis use it to control their brakes (which is just a little more vital than a pressure gage).

installing a mechanical pressure gauge is far from "crazy"

Properly routed and installed wires don't short out either. If my wire shorts, there is a fuse to stop the flow of electricity, what stops the oil...?

I'm just saying persons who are confident and experienced shall do as they please, but those who have to ask should take extra precautions. That simple little fitting, could easily get messed up. How many times have you seen a newbie tech screw up a simple brake line fitting and have a leak...?

FWIW, there are millions of semis and older automobiles all over the roads that run mechanical gauges and don't have problems. I have seen one oil pressure gauge blow out its pressure bulb while running down the road. It put oil behind the dash, but didn't endanger anyone, and was a slow enough leak the driver could get it to the shop from 60 miles away.

But that was the only one. Every other gauge I've seen was working just fine.

It's actually far more common for oil to enter the cab by the engine kicking out a piece, like a rod, and blowing oil into the cab's air vents.
