thread size on the oil pressure sender ? (1.7 4cyl car), Going to order some new gauges from Big Mark, need a bit of help Options

[nsr-jamie]

Hi, am just about to order some gauges from Mark (Big Mark) and before I order the gauges I need to tell him the thread size on the oil pressure sender of my car. He mentioned there are a few different ones, some metric others American sized. I thought they would be in Metric since our cars are European.

My car is a 1.7L 4 cylinder engine bored out to 2.2L with twin dell carbs. It has no aftermarket gauges for oil temp, pressure or anything other than the stock gas gauge, tach and speedo

I am away from my car for the next two weeks so don't have access to it and hoping to get my order on the way as soon as possible. Does anybody know the correct thread size please? Is it M10 or 1/8 or another size. I always thought they would be the same honestly have no idea.

Any help would be great, even better if so with pictures (IMG:style_emoticons/default/biggrin.gif)

Thank you

Yes it's next to the distributor . The little sender that operates the oil light in the gauge on the dash. If you are going to use a pressure gauge , there are senders available with the feature of suppling the gauge as well as the light. Some folks run a hose from the mounting port on the engine to this type sender mounted out of the way of the dizzy. Lots of the same guys use a grease gun hose to do this and there are some places to get a kit to do the hose adaption ( can't recall any at moment ) just be sure to get the fittings to adapt the hose , usually 1/8 pipe threads , to the engine block and the sender , McMark supplied the block and sender thread sizes. Very popular and has been done by a lot so someone should have pics of the setup , maybe in the classics thread. Good luck.
