Hello, I am trying to convert my stock gauges for my 51 F1 to the 302 SBF intake manifold. The temp sending unit is huge. Has anyone gotten this to work for either the stock 2V intake manifold or the Edelbrock Performer Intake manifold (#2121)? I have the speedo issue solved so that it can be used with my 5 speed manual transmission, but waiting on the oil pressure sending unit. Is there a 6V sending unit for oil pressure? I can't find one.
Why don't you convert to modern mechanical gauges that will fit your engine, that you don't have to voltage reduce and you don't have to adapt 6 volt electrical sending units that are expensive to buy - if you can find them.
Adapting 3 1/2 inch Supro mechanical gauges into your existing gauge cases and using the stock faces is a relatively simple process that only requires some minor cutting of the stock gauge case.
Look in my Galleries. There is a gallery that tells you the step by step and has a picture of each step.
I have done this with my oil and temp. Ammeter does not need to be modified, and gas gauge can be voltage reduced.
Here is a picture of my gauge package after the conversion:
I'm using the old oil pressure sending unit with my 12v system. I just added a voltage drop to the gauges. As noted in the picture and it works fine. On the amp meter make sure you run the wire thru backwards or it will show that your discharging instead of charging.
As your looking at the back of the gauges, normal 6v pos. grd. would run thru the hoops bottom to top. 12v neg. grd. start at the top loop than down and around to the breaker bar.
