Lukey. 381 Posted January 24, 2011 Report Share Posted January 24, 2011 yes they are, theres 2, one for high one for low, both the same thread Link to post Share on other sites
russj249 2 Posted January 24, 2011 Author Report Share Posted January 24, 2011 Perfect mate. cheers for that.can order the adapter now to make a turbo oil feed. just out of interest which one is the high pressure one? will probably use that one to take the feed from.

Lukey. 381 Posted January 24, 2011 Report Share Posted January 24, 2011 iirc think its high on the left low on the right, can check under the bonnet later as i have a VDO sender on the low so its easy to tell which is which, but really it doesnt matter which one you use they will both be identical size holes in near enough exactly the same place Link to post Share on other sites

Lukey. 381 Posted February 8, 2011 Report Share Posted February 8, 2011 if you are doing both just ask them for a high and low oil pressure sender for your reg, high on left low on right when you change them Link to post Share on other sites
Smurf 0 Posted February 8, 2011 Report Share Posted February 8, 2011 Hi Normally the oil pressure switches are 1/8" BSP taper thread don't use Parallel as it will leak. Always use either loc-tite thread seal or PTFE thread tape as well or it will leak. FYI to correctly fit thread tape hold the fitting in your left hand then travell around the switch thread clockwise with your right. This will ensure the tape seals when you tighten it!! without the tape falling off 1.5 times should do itPS if you have use parallel thread you have to use a special 1/8" BSP gauge fitting with washer.

russj249 2 Posted February 8, 2011 Author Report Share Posted February 8, 2011 Yep lukey's right. i bought a turbo oil feed t piece, that's m10 x 1 and fine.lots of companies i asked only had m10 x 1 listed for vw. the only thing that you could get in 1/8 is the side tapping for a feed or gauge. but i had an m10 x 1 side tapping too.
