Re: oil pressure guage
Yes - in line with the current sender there are 3 or 4 more ports on the block that you can connect a mechanical gauge to. Or you get get some fittings and have the stock sender and the tube for the mechanical gauge at the one spot Also could rig up an electrical oil pressure gauge the same way.

I made this up from my stash of brass fittings, but I'm sure there is a more efficient way to do it. Just haven't been able to find the right fittings in local auto parts stores. |

The previous photo of the pressure switch on an upside down engine was not the original engine for the car, a '55 T-Bird. That photo was meant only as an example of the locations of the oil galley fittings. I placed the pressure switch in that location because that's where it was on the engine that was removed, also not original to the car. The next two photos show before and after on what was an original, but now rebuilt, T-Bird engine Last edited by dmsfrr; 06-27-2023 at 08:14 PM. |

Re: oil pressure guage
Attached is an image of how I solved this problem, much like another responder who talked about using a "T" for both the manual and electric pressure sending units. Tried as I did, I could absolutely not budge the other port plug. Use a torch and everything else I knew to use, but in the end, this was the simplest solution.

Re: oil pressure guage
Hmmm. I have a 292 in my 57 Fairlane/Skyliner. I'd like to do the same, but I do not recall my bottom end looking quite like that. Perhaps it's because the motor mount is in the way on my car. I will have to get under there and take a look.

Re: oil pressure guage
The NPT port that dmsfrr shows just below the coolant drain petcock is the location for the oil sending unit on all 1955/56 Ford Y-blocks in full-sized cars.
It can be used as a combo for a mechanical pressure line with the original sending unit as shown above or similar, or you can use separate oil ports that are in line with the original sender (if you can get the pipe plugs out). By doubling up on the original port, you may have to lengthen the white/red oil sender wire to get it to stretch to the sender unit terminal. Originally, that wire was routed through the space between the engine block and the motor mount as a means of supporting the wire. Any modifications to wire length or routing should take into account how the modified wire lays in relation to super hot surfaces (particularly the back of the exhaust manifold). A little bit better and more efficient assortment of brass fittings can be found at most big hardware stores. |

Re: oil pressure guage
I noticed the exhaust in that area, and we think alike. I have a copper line for my gage, not a plastic one.

Re: oil pressure guage
I plan on routing both the copper tube and the electric sending unit wire through a "heat barrier" tubing (don't know what the technical word for it is) to help with heat issue.

Re: oil pressure guage
Here is a picture of the heat-resistant tubing I mentioned the other day.

Re: oil pressure guage
Heat problems for the plastic oil tubing can be avoided by routing the tubing up to the wire-harness on the drivers side fender apron. Fomoco provided a couple of spare "ports" in the rubber bushing where the wire-harness goes through the firewall. I just took my bushing out, drilled a 1/8" hole in one of those spare ports and poked the plastic tubing through it to my oil pressure guage under the dashboard. You can use a couple of little nylon wire ties to bundle the plastic tubing along the wire harness. Never had any trouble with it.
