Yesterday I decided to look into the dash gauge problem. When I turn on the headlights my gas gauge went up a little, the oil pressure went up some and the temp would go up some. So I thought I would look behind the dash. All was looking good until I decided to start the engine and wiggle some wires. But now the engine ran and run out of gas. Something I checked out was the inertia switch. Now that was something om '73 Winnebago didn't have. That checked out good. Then I looked at the low oil pressure switch that shuts the gas off if the oil pressure gets to low, a nice thing I guess.
Looking deeper I decide to just run a wire right to the fuel pump at the gas tank and it runs fine. Now to look for the fuel pump relay. Of course it is not labeled as a fuel pump relay but I think I found it.
Why do you need so many wires just to make some gauges work.
And I am going to go out now and look for the relay.
