Oil pressure gauge install.

[boostjunkie]

Okay, so I have this fitting for the block galley in my possession. Does anyone know the size for the oil pressure warning light fitting? I found this Autometer fitting that's a 1/8" NPT to 1/8" BSPT fitting that MIGHT fit in the stock galley fitting that I have. If this is the right size then it would save me the headache of trying to fit an MPT fitting into a BSPT fitting.

Thanks!

The stock oil pressure sender has 1/8" BSPT threading.

You're coming over to my place on Sunday to try to install this dealie, right? I have a spare oil gallery plug that we should try to retap to 1/8" NPT. I really think that'll work.

But if you'd prefer the adapter, I think that Autometer one would be the right one (assuming it's 1/8" NPT female to 1/8" BSPT male). There isn't a lot of extra room around there though.

Hey I installed a adapter kit from WRXtra on my 99 Legacy 2.2L kit and it was easy enough... I am new on the whole additional guage thing but I have noticed that depending on if my engine is reving high or is at idle speed my oil pressure is fluckuating when engine idle it sits around 20 PSI when in motion on public streets around 35-45 MPH it is at about 40PSI...on freeway I hit about 70 - 80 which I am told is normal. I'm just not sure if the pressure goign down at lower speeds is normal or not...I have the hose that came with this sender relocation kit not too straight and was interested if this might be the cause of that or I might just be worrying about nothing and this kind of fluckuating is normal if you could let me know that would be awesome.

I have Autometer Guages

Note: Engine is Warmed up at this time... when cold it sits higher which I know is expected

Yes, pressure should vary with engine speed due to the fact that the pump is run off the engine.
