Mine is sitting at 48500 miles, so I was hoping it was as simple as the relay, but finding it has proven to be a little difficult. The last time I replaced a fuel pump, I had to pull the tank and after the new one was installed and didnt work, I found out it was a $12 relay. So I wanted to cover the simple less expensive option first. I have yet to locate the actual pump at this point as well. I have followed the line back to one of the fuel filters but havent gotten to the pump yet. The only places I havent looked for the pump so far is between the rear dual axel and the tag axel. I am guessing it is either there up on the frame, or possibly in tank. My owners manual says the pump is located directly in front of the tank. With a filter before the pump and one mid way up towards the engine followed by a mechanical pump at the engine. But I believe the manual may be incorrect, because there is no pump directly in from of the tank that I saw and the fuel lines come up and go directly to the carburetor. So I dont believe it has a mechanical pump. Although I thought with a carburated engine you would have a mechanical pump at the engine. That may explain the 2 gas lines that go to the carburetor, the smaller line may be a return. I hope that makes since! Where was the pump located on yours?
