How do I "T" off the block so I can run the stock oil pressure and a VDO pressure sensor? I heard it can be done but haven't found anything on the web.
You just need an pipe thread tee "T"
I think the one you will need is called a street tee.
One end has 1/8" male NPT the other part of the cross bar of the tee has 1/8" female NPT and the leg is 1/8" female NPT.
Remove the factory pressure sensor and screw the male NPT of the "T" into the hole. Then the factory sensor goes in the top and after market sensor in the other hole running horizonital to the car.
Hope it make sense to you.
