Fuel Tank Problem
I have a 1984 Grand Wagoneer. I went to an electric fuel pump. The problem I am having is that when I fill the tank up I only can put a gallon or so in and then it overflows. I wait a few minutes and then I can put a little more in. I dont understand what the problem is. I am not using the return line and I have tried to plug it and leave it open with no change. I have the lines from the "carbon canister" open and that didnt help. Do I need to plug all the lines going to the tank and use a vented gas cap to solve this problem or something else. If anyone has switched to a electric fuel pump PLEASE tell me what you did with all your lines. I am a volunteer firefighter and I would like to use my Jeep to get to calls. I also have problems with it running out of fuel almost like it only uses a couple gallons and then can't use anymore. I had a 35ghp pump on it but I am replacing it with a 65-95gph pump. Any thoughts or tech advice would be appreciated!!!
