Hey guys, quick question. Any problem with just installing a t-fitting in between the engine and the OE oil pressure switch to installing my sending unit for my aftermarket gauge?
No, shouldn't cause a problem at all. Just make sure that you're using the correct fittings - I've seen pipe threads cross-threaded into straight o-ring threads too many times. It tends to cause leaks and thread damage.
Sure. Great way to do it.
Note where the oil is coming from. Is it at the end of the line, or in the middle? Being at the end of the camshaft bearings on a OHV engine will show lower oil pressure than off a main passage.
