felixx Posted January 25, 2012 Share Posted January 25, 2012 OK so I brought an old school Oil pressure Guage on the tard. It has a red and a black wire and a hollow plastic tube. OK so Red = live black = earth -or do these go to an accessory/ light switch? What do I connect the clear pipe to? I guess it goes somewhere different to my oil light wire connects Sorry for the noobish Question Quote Link to comment Share on other sites More sharing options...
Valiant Posted January 25, 2012 Share Posted January 25, 2012 Red = Parklight. Black = earth. Clear tube should have a fitting on the end to screw into the hole the oil pressure switch is in now. Quote Link to comment Share on other sites More sharing options...
keltik Posted January 25, 2012 Share Posted January 25, 2012 And make sure you do all of the fittings up tight and check for leaks and the quality of the hose....or you may find hot oil being squirted at 60+psi all through your dash/interior. 1 Quote Link to comment Share on other sites More sharing options...
governorsam Posted January 25, 2012 Share Posted January 25, 2012 put a "T" fitting into the block where the oil pressure switch is and then you can run the gauge and the light. Quote Link to comment Share on other sites More sharing options...
SOHC Posted January 25, 2012 Share Posted January 25, 2012 Super cheep has copper oil pressure gauge line with the gland nuts and tails soldered on ready to go if your missing the fittings. Quote Link to comment Share on other sites More sharing options...
felixx Posted January 25, 2012 Author Share Posted January 25, 2012 Pete.. cheers! I was worried about this keltik.. might replace it with copper tube. nice idea Sam... will look into that SOHC.. you typed that as I was typing this cheers for the feedback Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted January 25, 2012 Share Posted January 25, 2012 SOHC is correct, we have trisco kits which look fairly decent, and from memory not very expensive at all. have several different brass fittings. Quote Link to comment Share on other sites More sharing options...

Yup, that was me. The supercheap ones don't quite fit my BSF threads. Quote Link to comment Share on other sites More sharing options...

ProZac Posted February 1, 2012 Share Posted February 1, 2012 We sell the clear plastic tubing kits for oil pressure gauges at Repco. The copper ones are usually a bit nicer for a period vehicle, but the plastic ones can be cut to length. Quote Link to comment Share on other sites More sharing options...
morkster Posted February 2, 2012 Share Posted February 2, 2012 nylon not plastic? - anyway they're good - you can see the colour of your oil. i have the gauge inside and not worried about it bursting hot oil on me.. much Quote Link to comment Share on other sites More sharing options...
M_C Posted February 2, 2012 Share Posted February 2, 2012 My auto sparkie has seen two of the brass tee peices work harden and break off with less than ideal results for the engine. Anyone else seen this? I am planning on mounting my tee under the dash to avoid engine vibration possibly causing work hardening and maybe make it from steel.

Llama Posted February 2, 2012 Share Posted February 2, 2012 ^vibration isn't work hardening, it's metal fatigue. If you have vibration strong enough to cause work hardening, then you have bigger things to worry about . And yes steel is probably a good idea since ferrous metals have a minimum fatigue tolerance. Just be careful of it seizing if you are sticking two different metals together. Quote Link to comment Share on other sites More sharing options...
Roman Posted February 3, 2012 Share Posted February 3, 2012 The idea of a mechanical oil pressure gauge gives me the shits! Quote Link to comment Share on other sites More sharing options...
Spencer Posted February 3, 2012 Share Posted February 3, 2012 Yea for me its a cheap diagnosis tool only! buy an elctronic one, no oil in the cabin = good Quote Link to comment Share on other sites More sharing options...
Jase Posted February 3, 2012 Share Posted February 3, 2012 had one let go in gemini thankfully hadn't bonnet mounted the gauge like an ozzy, biggest pain in the arse ever buy an electronic one. ie if you do it carry kneadit to blockit if it snaps off, brakes line etc Quote Link to comment Share on other sites More sharing options...
BLIZZO Posted October 30, 2014 Share Posted October 30, 2014 Dredging this thread out of 2012 and into 2014, are mechanical gauges actually that bad? ive just got my hands on a genuine smiths oil pressure gauge for my triumph, i dont want any gay modern shit in it and the smiths gauge is dope as. Would ripco or supershit have the british thread fittings for these as it didnt come with lines, are the nylon lines better than the copper or stainless braid etc as i have seen a few different ones. I also got a smiths GP series vacuum gauge (and spare oil pressure), whats the best way to hook up vacuum? i wanted it as the lucas mechanical injection runs on vacuum so shes pretty important but, though of hooking up to inlet vac line somehwere. Help me Jim! Quote Link to comment Share on other sites More sharing options...
Beaver Posted October 30, 2014 Share Posted October 30, 2014 I think people are just scared of mech oil gauges cause if they break then oil goes everywhere etc/loss of pressure etc. I had a triumph which used to have one and had obviously gone wrong and all in behind the dash was oil splatter. For vac gauge, just run in from a vac line on the intake There might even be a couple of blanking plugs you could use. Quote Link to comment Share on other sites More sharing options...
anglia4 Posted October 30, 2014 Share Posted October 30, 2014 My capri had a mechanical one in and we forgot about it once when working on it with the dash out. Fired it up to check something and flooded the footwell. Ruined some really nice carpets that day. Quote Link to comment Share on other sites More sharing options...
