Hello ,
I am wondering what peoples' experience is on exhaust blowing near the gas tank? My xj is a 92, 4.0/AX15/231 with a factory steel skid plate over the tank. Recently I just replaced the airtex pump that was on its last leg with a bosch pump. I noticed with the airtex that after about an hour or so the pump would be humming loud in the tank. Eventually the airtex would be so noisy/hot that it would hardly even start.
After installing the bosch I quickly noticed how superior it is to the airtex. Hard to even tell the pump is priming. After a ride today for about an hour both city driving and highway mixed in I noticed no increase in pump noise. So as soon as I parked it I put my hand on the tank and noticed it wasn't hot enough where I had to remove my hand in a second or two, but that I could leave my hand there for a while before it would be too hot to touch.
My exhaust has a turn down pretty much right after the muffler so the exhaust isn't blasting it strait back into the tank. I would route it back as close to factory as I could but I have a small tube truss on the 8.25 that doesn't leave much room for piping to get past the axle.
Should I be worried about the new pump I just installed getting hot? I certainly don't want it to fail anytime soon.
TIA
Nick
