What brand gauge are you using? You shouldnt have readings that fluctuate like that

Just look up images of their hoods. I believe they have vented ones.

 

This.

 

Thanks for advise. I got it as high as the cap would let me. About 1-2 cm from hitting hood. I might attach it to the firewall. Did I say it’s a huge cap? Well, it is.

 

Autometer.

I even replaced the sender, thinking maybe it was bad. It didn't change anything.

 

Theres something faulty with the gauge itself then.

 

I have tested the gauge. It behaves as expected.

 

Yes, these caps are too big. Farthest off the firewall is best. I'm going to relocate mine...for the 4th time.

 

Your 90° bends at the intercooler inlet/outlet are cut low so that helps you as it's the highest point besides the res.

 

Had i known the cap was as burly as the trucks gas cap I would have bought another tank.

 

Yeah. I pretty much go mine way back when you first posted. Was kinda quick on the trigger. Darn Amazon prime [shakes fist]

 

I do that too often. Today's damazon was an arb camping chair and 3 s/c hose coupler fittings someone posted

 

If the gauge and sender are good, it could very likely be where it is getting it's reading.

What brand sandwich plate, and do you have a picture of it installed?

 

That is really my question.

Here is the plate:



Mounting location:



Installed:

 

Ive never heard of a sandwich plate causing readings like that. Really think you should have conatant readings there

 

That's what I thought.

Listening to the engine, I don't have an oil pressure problem.

 

That is an Autometer sensor? That is a very old style.

No leaks from the Glowshift adapter?

 

Quite a few companies still sell that crappy style sensor. I never had luck with them. Usually can find the better sensors within the same brand at a higher cost

 

Not sure how your wiring is ran but its possible you are getting noise interference

 

They are antiquated to say the least.
