My gauge and sender unit arrived today, installed it but wasn't easy, installing the T piece and senders was no prob, but putting the starter motor back in was a pain because the factory sender unit now sticks further out and over the top of the top starter motor fixing bolt. Could only get to this bolt from underneath with a lot of difficulty, also there is a small bracket under this bolt that supports a wiring harness. i had to cut the corner out of it to clear the sender. But got there eventually. By the way this is the place the factory manual says to measure oil pressure. Fired the engine up and was reading 40 psi at idle.
