Stock style gauges - Temp Sender and SBC
I purchased a set of stock style gauges (12V) for my '51 pickup from classic parts a couple years back. I'm finally now in the process of wiring/ plumbing and have ran into a snag.
The temp sender on the stock style gauge has probe that is too long. The probe bottoms out before the 1/2" npt threads can engage. It's about twice as long as the probes my donor '87 350 had in both the intake and head. Anybody run into this?

Re: Stock style gauges - Temp Sender and SBC
You can't modify the bulb on the end of the capillary tube so you have to find a way to raise it up a bit.
I'm thinking there is an adapter that is basically a male/female pipe nipple that does the trick. I'm rather thinking that you need an adapter like this one https://www.summitracing.com/parts/atm-2264/overview/ Or this one https://www.classicparts.com/1941-55...ctinfo/24-811/ To connect the stock unit to the later head. Most parts houses have those in stock. Those bushings have a pipe thread on the outside and a 5/8 thread on the inside with a seat for the flange on the bulb to sit on and be tightened down by the stock size nut.

Interesting, I'm gonna have to do some more checking... i was under the assumption that the head/manifold plug size was the same as the stock gauge senders thread. Hence i couldn't use an adapter... Maybe it fooled me a first glance and one is bigger. Thank you.
