My tank builds up preasure after running for a while but I haven't had any problems and have put about 5,000 miles on it.

Would attaching the return line toward the bottom of the tank cause any issues? I just don't want to hear a waterfall behind me.

Secondly, I heard external pumps are not designed to pull thru a pickup tube and they can burn out. On mid to late 80's Ford Bronco's had an external and internal pump. The pump in the tank is a low pressure/high volume pump to get the fuel to the high pressure pump half way up the vehicle which in turn increased the pressure to the engine. I had a 1986 Ford Bronco with fuen injection that ran at 48PSI that had this pump setup with over 145,000 miles. Has anyone came up with a way to implement a low pressure pump in the stock tank to push fuel to the high pressure pump? Thinking this may help extend the life of an external pump.
