Any way to tee the oil press sending unit to run the factory gauge and a aftermarket electrical guage or do I have to run a mechanical oil press gauge?
I'd rather run electric, I don't like mechanical guages

You can tee it and run whatever sendor you want. I run one electrical (factory) and one mechanical.

BTW I chose my aftermarket oil pressure to be mechanical because I know it's TRUE

I'm having a brain fart lol the factory gauge is electrical correct? So how would I go about teeing in a electrical aftermarket gauge? Just run both wires to the same sender or do I have to run two different sending units?

Ok cool thanks, is it possible just to use the factory sending unit hole and install the aftermarket gauge's sending unit? The gauge I was looking at includes a 1/8 npt sender and a 1/4 not adapter

Thank you sorry for so many questions just trying to figure out a plan
Do you know what size threads are in the block?
Also the oil press sending unit is in the same location on my 351 Windsor correct?

Thanks again

Also just curious but can I do the same for the water temp too

Yes you can, but if you don't install the sender for your dash gauge it will be dead, if you don't mind a dead gauge then go for it.
The easiest way to do the temp sender is to buy a t-stat housing that has a hole drilled and tapped on top for a sender, its the easiest way to add a second sender

Can I tee the factory water temp sender with the other temp sender that goes in the intake?

I tried that. It doesn't work very well. Very inaccurate readings. Buy a thermostat housing with the threaded port.

If one wants to use the stock sender and an accurate aftermarket sender then get an adapter. Both my 72/5.0HO and my 96 5.8 have the angle adapter below.
Just about every Mustang racer has one because the aftermarket sender is too big to fit, thus an extender is needed.
You may have to clock the oil cooler in the case of the 5.8 and you will have to use red loctite on the adapter threads because when you get the adapter clocked correctly it may not be tight?
Let me help you with using Google.
Search for “ford pressure sender adapter” without the quotes

Put a tee on it and you have 2 senders. maybe use a 45 deg fitting as well?
Here is a 90 deg & straight combo version

I've been wanting to do this for a while but cannot find a housing that has the threaded port. Any links? Thanks

99% sure the oil pressure boss on the block is 1/8" NPT.

I have no idea where to get the threaded thermostat housing, but you can buy an "in hose" coupler to put your sender in the upper radiator hose. I know that the housings with the boss for a sender do exist-- at least for BBF. My EFI 460 has a boss on the thermostat housing. I doubt it's factory, but I have no idea where it came from...

You could always make your own, you can buy aluminum weld on npt threaded bosses, then just drill a aluminum neck and tig one on. Also, a lot of the aftermarket "performance" necks look to have a thick enough casting that you might be able to just drill and tap.

Good Luck,
Jason

Go to O'Riellys and ask for a thermostat housing. It should have the threaded port. That's how I bought mine.

If I were to add a second gauge, I would add a mechanical. I like mechanical gauges over electrical, but electrical are generally easier to run. Most of my experience has been with Auto Meter, so it might not be accurate compared to other brands.

If you run a mechanical, toss the plastic line and use either a brass line or a braided line. Nothing like having a plastic line leak all over your carpet.

Water temp gauges, like Auto Meter, include a capillary tube that "feeds" the gauge.

The block, and adapters, for the oil pressure gauge are pipe thread. You can go to your local hardware store and generally find everything you'd ever need to plumb it away from obstructions. Some of the older 289/302s have a long octagonal tube that is sturdy and easier to work with and exits at a 45 degree angle.
