Okay, i put the NWMP 43 gallon gas tank in my blazer in july. Everything went fine until i filled the tank up all the way for the first time. Then the blazer ran like crap for a few weeks. It wouldn't idle, could barely get it to run the 2 miles to work and back. Then, after a week or so, it ran fine. Well, the other day, i filled it up again. It started doing the same crap. It seems like its not getting fuel, but then it smokes really bad, maybe like too much fuel. It only does it when the gas tank is full though, so i'm very confused. Anybody have any ideas?
