Water temp and oil pressure gauges.
What do you all use for aftermarket gauges? It seems like these "universal" gauges don't seem to have the right fittings for the motor. 1965 225/6 1 bbl auto. I just got a universal water temp gauge and all the fittings look too large for the small /6 temp sending unit. I really don't want to drill and tap. Anybody have a simple answer?
Also I have an oil pressure gauge for a 318. Will that sending unit work on the /6? If not what's a part# for a gauge I can use. Thanks all.
I once installed the sensing unit for a mechanical water temperature gauge In the water jacket drain opening down below 5 and 6 sparkplugs. It was really surprising how long it took for warm water to get back there to move the gauge. So I would not recommend that.
If the correct size fitting is not already in the head,
1) does your climate require a functioning heater/defrost? If not you can thread it into the head heater outlet.
2) I have seen connectors for putting water temp sensors in the upper or lower radiator hose.
For the mechanical oil pressure gauge, just T where the existing oil pressure gauge connects.
for the gauges, those are not complex devices, what is on the shelf at your local NAPA or other auto parts place should be good.
Concerning the plastic hose for the mechanical oil pressure gauge. I have never had an issue or leak. But there are those that have, be carful in the routing for snags, kinks, hot engine parts that will melt the plastic. Lastly, know what you are doing when assembling the Ferrell and nuts.
