59 AB in 35 ford maxing out oil pressure gauge

[hueyhoolihan]

i recently installed (successfully) a new oil pressure sensor, 4" sensor extension, and dashboard gauge in my '41. i also had to fabricate and install the solid brass/copper plate that runs power from the gas gauge power stud to the oil pressure gauge power stud to as someone had removed it. an insulated wire will not do, it needs to be a raw plate of conductive material in order to dissipate heat properly, from what i can tell. in any event an insulated wire in its place almost caused me an electrical fire on two occasions. good luck.

the new extender and the NOS dash gauge were purchased from Ebay, the oil pressure sensor was bought from one of the usual suspects and was recently manufactured. everything worked well. YMMV of course.

That'll raise hell with the rate of inflation!

There is no inflation, They just printed much more fake money so your old money is worth half as much

Those NOS 50 LB senders have been really scarce for a long time. When I was doing my 42 Ford project, I really needed a 21A-6312 crankshaft pulley which was holding up the whole project. None of the usual suspects had one. I'd be embarrassed to say what I paid for the one I did find. I was going to paint it gold for what I paid! It balances out. Some things cost next to nothing and others you wanted to puke but you needed the part. The aftermarket is reasonable but if it doesn't work not a good deal.

Update #2
I have installed a 50 lb. oil pressure sender from Kaiser Willys Auto Supply, part number 800807 using a 1/4" NPT to 1/8" NPT reducer bushing.
The gauge is working properly now.

good to hear! not surprised...it sometimes takes a few attempts. i've got plenty of parts that i'll never used to prove the point! ha

our problems weren't the same but i reckon our satisfaction when rectified was just as satisfying.

I am mildly surprised that none of the old-timers mentioned the Jeep sender. I didn't mention it because I wasn't positive. THAT much I've learned from past embarrassments!
