Title: oil pressure guage??
Post by: ROD on March 01, 2015, 05:35:58 PM
The joint at the guage end of the pipe is leaking, and I cant cure it .The pre made pipe that can be bought with the correct ends is far too long , as I only need about 15 ins (oo er).what I really need is a pipe with a'banjo fitting one end, and the correct guage fitting at the top end.
Or should I just blank off the t piece and do away with the guage? Opinions please.

Usual thing is to neatly coil up the excess tube.
The end fittings used to be soldered on to copper tube and it was possible to shorten the tube and re solder.

Think I may have to rethink the whole t piece to fit sender and pipe to! Probably easier to buy npt tap and die and custom make it!

This is how i did it Rod, may be of some interest to you. shaped aluminium, drilled a hole through then tapped it for the oip pressure guage, a sender and a connector.

Thats a different way of doing it Andy, looks good. What sort of tube did you use from block to the aly then? The tubes and fittingsthat are sold for the job are crimped/pushed on by machine, yours look just clamped? What about the pressure blowing the pipe off the connector tails?

Do you need an oil pressure gauge ?
Never bothered with one. As long as the oil light goes out (and stays that way) I'm happy. One less thing to mount, plumb in, run wires to and worry about. :)

I agree, but with the troubles Ive been having, I want to monitor it if I can! Removed the pipe and gauge and blocked the hole in the t piece for now.Ive now sussed the thread sizes ,think Ill fit an elbow facing upward to the block, then a t piece for the sender, then sit the gauge on top of that, facing upwards.No pipe to bother about sourcing then.

I've got a small direct fit oil pressure gauge on my truck. Screws directly into the engine, (mine actually goes into the oil filter housing). About 1 1/2" diameter. So you  don't need a separate sender unit & could mount it on a simple 90 degree elbow to make it readable from the riding position.
Cost about 35 quid from Jackhammer hotrod shop in Farnborough, Hants.

I think that by sender unit, Rod may be referring to an oil pressure switch for the oil warning light.

Thanks Andy.Yes I was talking about the warning light sender.
