I've resently made my 77 fj40 a daily driver. I've been doing a bit of highway driving with it. I'm running a stock 2F(suposedly rebuilt a couple years ago...) weber carb, 32" swampers and stock 4 spd tranny. For some reason the oil pressure gauge is all over the road. Sometimes it'll be just a bit above the low of the two range marks. If I floor it, the pressure plumits. Then it won't usually come back up. I drove 3 hours averaging 60-65mph and the entire time the gauge was all over the road. Unfortunately I have no tach so all I have to judge the engine's strain up and down hills is my ear. On that same trip I had drivin' for about an hour and a half. The pressure was really low. I stopped for gas and checked the oil. I immediately got back on the highway and went the same speed. This time the pressure was just a hair above the low of the two range marks. It's never been over half way between the marks except in the mornings. My questions are (finally):
1. Has any one had similar problems?
2. Is it a. the engine (please say no) b. the sender unit or c. my gauge?
Also because of this problem I'm getting custom gauges. What ohms does the fuel gauge need? and better yet is there a website with this kind of little spec/info so I don't have to ask?
