What size is the threaded hole for the Oil Pressure?

[blackhawk60]

I am putting in a "TEE" for my autometer gauge for the oil pressure. I would like to know what size "TEE" to get in able to use the existing sensor as well as my new nylon line.

Hasn't someone done this before?

I am pretty sure Fred has. I am going to do this soon also and would like to know how.

I think it's 1/4" NPT... the width of the actual threaded end is about 3/4" wide. Don't ask me how pipe thread crosses over to hole size.

You could just skip the T part since the light isn't important when you have an actual gauge - plus some senders have an idiot light connector AND on top of all those reasons, it's a bitch to fit your hand down there in the first place, much less put a whole crazy T with two senders on.

You must buy the fittings at Home Depot or other place that sells plumbing supplies because auto parts stores don't sell them.

Bring your new sender with you and fool around with the fittings until something works out. My sender had a 1/8" NPT fitting (roughly 3/8" wide) and came with some adapters to various sizes.

I used a 1/8" NPT male to two female 1/8" "tee". I kept my idiot light and have my guage too. And to put this in, do it from the bottom of the car, it is much easier. There will be almost nothing in your way. Just make sure to have the vinyl tubing that goes to the guage not bent too much.

Bleh.. don't use a mechanical gauge I'd rather have the single wire to the sender break than the teflon tube near the hot engine parts break or melt.

Those tubes are highly underrated. Unless routed wrong, they will not break or crack even in cold weather when treated properly. Autometer would not use this type of tube if it wasn't reliable. Plus mechanical gauges are far more accurate and durable.

You could get a braided hose (for NAAWWWSSS).. the right fitting sizes are on shotimes.com.. I agree on the fact that they are reliable or they wouldn't have sold for so many years.. but one sharp edge or a hot header and your engine is toast from lack of oil.. or it bursts in the cabin and you're soaked with oil plus dead engine.

Also, I don't know if it would be advisable to run a mech oil gauge in an A-pillar.
