oil pressure sender location
Posted by: DOUG WARD ()
Date: May 17, 2022 08:21PM

I have an extra electric oil pressure gauge on my 180 hp Corsa. I'm not too happy with how I had to plumb the extra sender ( in addition to the oil pressure switch)because of all the additional oil lines going to the turbo.
The 45 degree adapter has a 3" pipe nipple going upwards & forward from the alternator mount to about the center point of where the belt is, then Tee's so I can mount the switch & the sender for the gauge. It's long enough that I see it vibrating & I fabricated a brace for it. It's pretty ungainly & crowded. How have you guys dealt with this ? I wish I knew how to send pictures for you but I just can not seem to get the hang of all that.
I'm not too sure how to go about mounting the sender remotely. It would have to be mounted on the engine & not on the car frame & I don't want to use hose to make the connections.

Here is a solution - installed by my Corvair mechanic at the time.

Obviously, your turbo oil line adds complexity.

45 degree fitting in the original oil pressure switch hole.

Here is how I installed both the Pressure Switch and Oil Pressure Sender!

Of course, this is a 1967 110 PG!

Adapt-a-bolt from Clark's is a good option.

Guess it is too late (or ?), but I cannot find that bolt in Clark's online catalog?

Clark's still sells them. Find oil pressure listing and it will be there C7521. I got an electric sender and gage from Summit. I didn't want to run a oil line to the dash.

I still sell my version (which was discussed in Doug's similar thread last fall).

You're wise to be concerned about too many things vibrating on a single 1/8 NPT stalk in 50 year old aluminum.

As an aside, you've got me thinking that a low stressed 61 80 HP crankcase with the additional port into the lifter gallery might be a good place to start when building a Hot Rod EM. I wonder if they gave up on that design because the extra heat caused the sender to fail or because it was hard to get to or maybe more expensive to manufacture. But then again I'm usually satisfied with just a light.

Not much new under the sun. Here are several other solutions for tapping into oil pressure points. Thread from 2013.

I bought RobertC's version and I'm extremely happy with how it turned out. I'm able to see my pressure when I really need to, that is, when I'm checking the engine, but it doesn't clutter up my engine compartment or my dash on the other end

Why not put a T fitting where the oil line enters the Turbo ?
Pressure too low there ?

That fitting at the turbo is a compression fitting and most oil senders are 1/8 npt so you'd need a tee with a male compression, female compression, and 1/8npt. You would also have to shorten the hard oil line to the turbo. Seems like a lot more hassle than other options.
