Intermittently my OEM gauge won't show a pressure indication on cold start. First time it happened I freaked out a bit but quickly discovered the issue was electrical and not mechanical.
I didn't want an aftermarket gauge but I did want a fully functional oil pressure gauge. On my 1993 F-350 the oil pressure gauge mod was a simple as installing a 60psi sender and jumpering the resistor on the back of the gauge. No so with the Expy. I think I heard about Accutach from a post on Expedition Forum but maybe not. The Accutach option was cheaper than an Isspro EV oil pressure gauge. I love the Isspro EV gauges but not the price.
At the last oil change I swapped out the failing pressure switch for the Accutach recommended Autometer oil pressure sender. (2242 for 100psi) That job didn't suck as bad as I thought it would but it wasn't fun either. I threaded the sender directly into the oil port. There's not much clearance between the sender and the diff case. I don't know how much the engine might rock side to side and I didn't give it any thought at the time. Just occurred to me as I was writing this.
