I was having fuel guage issues. One afternoon I pulled out the tank and removed the fuel pump unit because I thought maybe the contacts had been worn off the sender unit, everything tested fine so I thought, loose connection, connected it up back to the vehicle and the unit worked when I moved the armature. Thought to myself "Cool I've fixed it". Put it all back together filled the tank and What do you know, it didn't work. I'm now going to guess and say the float is full of fuel. I haven't removed the tank to check it yet as it is full... The question I have.... Are replacement floats available to buy or do I have to buy a new pump??
