oil gauge sender

[thatotherguy]

hi all does anyone know if red motor V8 oil pumps have different threads to blue or black motor oil pumps thanks

Dunno about the threads but I've been having issues with the sender on a VH motor installed in my HZ. I'm assuming the senders are different as its currently going all the way to high on the gauge when the engine isn't running and then dropping down most of the way once pressure builds up.

Have you got a part number or a pic of it you can post? Sounds like either a oil light sender or a funny earth/electrical contact through the thread of the sender. Have you used teflon tape (or similar) on the threads? That can cause conductivity issues. Not telling you how to suck eggs, but have you checked all the simple stuff like wire condition/chafing/shorting on firewall etc?

Can quickly test the gauge by popping the wire off at the sender and shorting it to earth with the IGN - ON. Should head straight to high. If it doesn't it may have a gauge issue.
