Evening,

Well got a lovely Smiths Oil Pressure gauge from sqweaka and now I'm in need of the fitting bits as its just gauge with no other bits.

http://www.moss-euro...Mini_UKCMS0044A

Now then I know I need the pipe that goes from the back of the gauge to the block were the oil presser sensor is (for the little oragne light of death on the dash) which (from moss) is parts 8,7 and 6 BUT 6 goes to a rubber pipe which I've not seen used for oil pressure and I wouldn't like to know the chance of the pipe going pop with 60lb or pressure going thro it to drive the gauge. Or is it suppost to be like that?

Also I have no idea what bits for the block I need, I've seen these big brass blocks that go were the original pressor sensor goes and then the gauge feeds from that with the original presser sencor on the end, do moss do these. I knowe I keep saying moss but they go that sale tommorw so I need to save a little cash.

Basical I just need all the bits for the gauge. Then I can hook it up and drive around merrily knowing my pressure is going funny.

Oh and its this sort of gauge.



Cheers for any info.

Your picture didn't appear (at least not for me) when I read your post. I also couldn't get the link to load (it timed out).

Regardless, the rubber tube bit you're talking about (presumably) is what I remember on older cars like mine. There is a piece of copper tubing that attaches to the block and another bit that attaches to the gauge. The two copper tubes are joined by the rubber tube. Trust me, these won't blow under a mere 60 psi. They were designed just for the purpose of carrying the oil pressure and they allow the engine to rock without fatiguing the copper tubing. That said, I chose not to use them when I put my engine back in.

I purchased a generic oil pressure installation kit with copper tubing (there are also kits with nylon tubing). The kit should include a female compression fitting that will fit on the back of the Smiths gauge. There will be a length of copper tubing and finally a male threaded compression fitting to go into the block. You may want to visit the home (DIY) center and pick up a comparably sized "T" piece and a pipe nipple. That will allow you to fit the nipple and T to the block so you can operate your old warning light AND the new gauge. While there, buy a roll of Teflon pipe sealing tape and use it on all the threaded joints.

Strictly speaking, the back of the Smiths gauge is supposed to seal with a flat-faced fitting and a sealing washer. However, I've never seen replacement sealing washers for the back of the gauge so I've resorted to using Teflon tape on the gauge threads and the female compression fittings supplied with the oil line kits. I have never had a problem. Don't forget the Teflon tape.

Lastly, if you run the copper line all the way from the engine to the gauge, route it away from the exhaust. Somewhere along its length form a series of 2 or 3 coils about 1.5" [40mm] in diameter so it looks like a still. The purpose of these coils is to absorb the rocking motion of the engine and reduce the chance the tubing will fail by fatigue.

On the other hand, you could just visit Mini Spares and buy their high performance oil line kit and their T adapter... it depends on your budget.

I was thinking more of this oil line kit from Mini Spares:

Though I've run plastic tubing for oil pressure gauges, once you split or otherwise crack the line, you'll wish you used something better.

so not avalible from moss then.

rolloxs. Wanted to get that 20% off too.

Cheers all.
