my electric autometer gauge seems to stay at 50 psi.. why?
 

just installed it today. i put it in the spot that sits on top of where the oil filter is. i turn the key on and it goes to 50psi.... i start the car and run it, it stays at 50psi.. run it thru high rpm... stays at 50psi! whats up with that? thanks for any help that u may provide!

First things first- check all of your connections. You may have reversed some of them.

+1 you got something backwards.

That is right around what an LS1 will be at normally 40-60, but it shouldn't move at all until you start the car. Check the ground wire

thanks fellas, i shall do that and post what i did wrong lol

all connections are correct. im guessing the sender could be bad, so im going to get a new one sometime

did you use teflon tape on the sending unit?

indeed i did. it said to use A sealer so i figured teflon tape would be fine. its not leaking or anything, but do u think its messing up the ground? because on the directions it said the sender should ground itself. maybe i could touch a wire to it and to a good ground and have a friend look a the gauge to see if it changes anything before i go taking it out

that happen to me once with using teflon tape. Try using a liguid or paste pipe thread sealant instead of teflon tape.

What you can do is bench-wire it. Don't install the gauge in a pod or anything, but keep it loose so you can check the connections. If you are sure they are right, and you are SURE you have a good ground, then replace the sender.

Does the pressure connection on the LS1 fuel system require that you remove the core from the valve?

lol this is an oil pressure gauge, not fuel.
