Another trivia question. Adding factory oil pressure gauge to dash cluster, looking for the location where the oil pressure sending unit goes on a 440. Anyone know? Thanks

just to the back of the rear of the valley pan on the engine. It will be the smaller plug, and there should already be a sender back there....how about pictures of the truck your working on???

Thank you for the info. The weather is just starting to show signs of spring. Should be 60 this weekend but rain. I will take pictures soon and post. It has been great to work on. Being a California truck all the bolts come off with ease no rust or frozen issues. Very simple in design and mechanics the way they should build them. At least my gas pedal does what it's suppose to do!
