SixasStandard Posted July 24, 2020 Report Share Posted July 24, 2020 Hello All, I'm currently planning on spending this month's sweetie money on the required gubbins to connect up a newly installed Oil Pressure gauge in my Vitesse. The gauge is a period correct Smiths mechanical jobby, and on the advice of an experienced Vitesse owning friend (hope you're keeping well Richard) I'm going to be using braided flex pipe. My question relates to the thread size of the sender on my '68 Mk1 2L Vitesse.........is it 1/8" BSP? The only reason I ask is that I've seen a 'T' adaptor being punted on E-Bay that purports to be for various Triumph models (including the Vitesse) but which specifies a 1/8" NPT thread. https://www.ebay.co.uk/itm/SPITFIRE-DOLOMITE-STAG-TR6-GT6-VITESSE-1-8NPT-OIL-PRESSURE-GAUGE-ADAPTOR-II/122637100866 Also, what is the recommended method of making the connection at the sender end? the braided flex pipe that I'm planning to use has female connectors at both ends. https://www.ebay.co.uk/itm/Braided-Oil-Pressure-Gauge-Pipe-6ft-1-8-BSP-Fittings-Flat-Ends-041-6/283888602531 Any help or advice greatly appreciated (as always).

Pete Lewis Posted July 24, 2020 Report Share Posted July 24, 2020 with out a browse i expect the hole is 1/8bsp and the switch /Tee is tapered so 1/8NPT that a Guess why not use a brake hose to decouple and cunifer up to the gauge on mine its just nylon all the way you only need flexible to reduce engine vibrations/ noises being transmitted to the dash Pete Link to comment Share on other sites More sharing options...
Paul H Posted July 24, 2020 Report Share Posted July 24, 2020 Can’t help with the thread gauge other than mine was secondhand from Spitfire Graveyard and was originally from a Spitfire . Here’s a pic of my setup on my Mk2 Vitesse Paul Link to comment Share on other sites More sharing options...
Guest Posted July 24, 2020 Report Share Posted July 24, 2020 Hello Ian, I'm well - thanks. Looking at Paul's useful photo I have the identical set-up. You will note that Paul has a couple of wraps of PTFE on the sender threads, I did this also as a belt & braces and never had a leak. With regard to the gauge, you must ensure you have either a rubber or leather O ring when seating the pipe in to the gauge, otherwise the oil will drip on to your nice new carpet !! I chose the braided option as I thought it looked better and it fitted in well. Job done really. I have a spare sender unit in the garage complete with pressure switch, if it is of interest ?? You could try this to check the set-up and will be better placed to make a decision. Regards. Richard. Link to comment Share on other sites More sharing options...

I've ordered the appropriate 'T' piece and adaptor for the Vitesse from James Paddock, and the 6ft braided pipe from E-Bay..........so I'm now sorted, but thanks again for the offer. That's a good point about the rubber washer when fitting the pipe to the gauge, so I'll be sure to get something if it doesn't come with the braided pipe. It would be a heart breaker if I coated the new carpet set in oil!! All the best, Ian Link to comment Share on other sites More sharing options...

The seal is specific to the gauge, I purchased quite a few at Stoneleigh this year. Link to comment Share on other sites More sharing options...

I'll have to check my spares stash to see if I have any lurking in the bottom of a box somewhere. Ian Link to comment Share on other sites More sharing options...

Peter Truman Posted July 24, 2020 Report Share Posted July 24, 2020 where do you get these little seal washers that go on the gauge male union from, I've had to make them for years by turning down reasonably thick fiber washers it's not overly successful & I'm, not happy in using an O ring as the appear too soft. Can you advise the supplier please Link to comment Share on other sites More sharing options...
