Help.. oil pressure sending unit missing

[warhorse]

Im sure this has been covered, but I have been searching for two days and cant find anything on my specific question.... Here's the deal, my 40 oil pressure gauge was not working, decided to go aftermarket with mechanical. Heres my question, there is no sending unit on the block. where am I supposed to screw in the mechanical line, and if there is no unit on it now, how is it there is not oil shooting from engine. Does it screw into A or maybe B and it was filled. Thoughts?

Looking into the engine bay, look to your left toward the front/bottom of the block. Looks like a bell if i recall in my head. If OE, has one wire that attached to the tip of the bell.

That pic to me appears that you are looking on the driver's side of the block towards the front, bottom. You need to look for it on the passenger side, below the distributor. On the oil cooler you will find the sender.

Some of the early 2f motors had the pressure switch on the oil filter bracket, Not on the side of the block like the later ones.

If you have an oil cooler on the passenger side of the block, it's probably on the cooler. Thats where mine is on my 79.

still no luck... this is a 76, I dont believe it has an oil cooler, but I could be wrong.

The sending unit on my '78 is on the bottom of the oil filter. I unscrewed the sending unit, screwed in a tee and put the sending unit on the end so I have both gauges working.

only thing on bottom of my oil filter is the 4 bolts that mount to the engine....

 

[warhorse]

can i just unscrew one of these bolts and put the plug fitting there? Should I put on my scuba goggles?

 

[3_puppies]

if your going mechanical, are you using copper line??

 

[warhorse]

yes i am going with the copper line, that is if i can find where to put it

 

[Landpimp]

AFAIK it should be on the oil filter bracket.......odd yours has none

Ran into this a couple of years ago, was fising a Cruiser, the filter bracket was broke in a wreck, I grabbed one off a junk engine, it was an FJ60 era and had no provision for a sender.
Maybe this is what you have?
BTW the "C" in your pic will drain the coolant

My 75 port that I use is on the drivers side below the maniflolds, I beleive where you have the C. Will check and take pic in am. you can pull that plug and turn it over and tell if that is a pressure port

Give me a day and I will snap a pic of my 76. I am positive it is on the PS.

My is on the drivers side just below the exhaust port nearest to the firewall. The motor is a 75 2f and the origanail sensor was there. IIRC this is near where it was with the org f eng. Hope this helps

On the driver's side of the block, near the bottom of the vertical part of the block, just before it bulges out for the crankcase, there is a horizonal ridge that runs the length of the block from front to back. This is the main oil galley that feeds the crank. There should be a plug somewhere along this ridge. Not close to it, not slightly above or below it, but RIGHT ON THE RIDGE.

IMO, since you have the option of running a sender feed on the passenger side, using the appropriate oil filter bracket, I would consider it. Most mech oil lines are less than leakproof, and not having the line close to the exhaust is a good thing.

Mark, Do you think that I have my fitting too high on the engine? It idles warm @ 30 psi and 55 psi and high rpm.

Thanks for all the help guys, I will make a post when I get It hooked up...
