engine and drivetrain Vdo Oil Pressure Sender Install

[bnam]

I got a vdo 0-80 gauge this am from a PnP, so searched a bit on what sender I should use.

 

Does the sender use a M12 size thread?  If so, this seems to be the sender:

Can it be installed directly without an adaptor?   A few pics that came up in search show an adaptor being used.

 

Thx,

Byas

0-80 psi? could be a bit low 0-100 psi better

m12x1.5

 

the sender is only necessary if you need to change the angle of the sender otherwise the new sender can directly replace the original

I agree with Tim up above. I had a 5 bar gauge for a while and when the motor was cold, the needle would bang against the stop because the pressure was too high. But, PnP prices are hard to beat and it's certainly better than no gauge. Once the car warms up it won't be an issue anyway.

You'll be fine with the 0-80 VDO oil pesssure gauge.  I've had one in Hans for going on 10 years and the range is more than adequate.

I think it is a tight fit without angle adapter

Does a washer need to be used with the sender?  Some ebay pics show a washer.  I think not, but wanted to confirm.

Might want a copper crush washer in there...it's oil,(and pressure!) right?

 

   M12 threads right in, M10 needs an adaptor.

Hey Byas, what model axe did that come from? Nice score.

Hey Rob!

I found these in a VW Bug at the Rancho yard.  Was looking for some parts for my '71 vert.

If you want to use the oil temp gauge, look carefully at your oil filter housing.  On the 71 and later cars, there's a small dimple in the casting--that's where the oil line that services the injector pump goes on a tii, but it's undrilled on the carbureted cars.  You can drill and tap that for the temp sender unit, and you'll have oil temperature as it leaves the filter.  

 

Nice score on the gauges, BTW.  But if you live in a cold climate, be advised that running 20w-50 on a really cold morning, I've pegged my 150psi gauge.  Even with temps in the 20s, I've seen well over 100psi--on a 200k engine.  So be careful.

I agree w/ Mikey…I see over 90 on cold day start ups.

Yep with what Mike said.  Thick oil + cold temps = high pressure.  I've seen pressure as high as 70 psi in my car, and that's only running Red Line 15/50.  In Houston, where it doesn't get crazy cold.

Niiice. Never thought to look in a bug for gauges. Sciroccos and rabbits , but never bugs. Those look new, nice score.
