white/blue smoke only on front tank :(

[04mach1]

well im sure everyone has read about my fuel problems and stuff with my truck..
well i found my leak and its the hard lines ontop the inake that go to the injectors. i found 2 of them leaking.
so i tried to tighten and they wont stop. so i purchased all new lines.. BUT this isnt te purpose of this post.

the purpose is that when i switch to my front fuel tank the motor starts to idle wierd and the diesel sounds goes away also when you hit the gas pedal it kinda chugs up to the rpms..

also it blows white/bueish smoke out of the exhaust like ALOT OF IT.. my uncle works for greyhound and he said to just let it run since its like there is water/ something in the fuel... im kinda scared since in a gas motor white/blue smoke is oil burning which means its not around the pistons rings and not lubing the motor..
i dont want the thing to blow up so i haven ran it on the front tank...
any ideas guys????
thanks

sounds to me like the "sock" on the pickup for the front tank is plugged, causing the fuel pressure to drop......
