I reciently had a 351w installed in a bronco that I have had for a while. I assumed that the engine builder drained the fuel tank but after about 5 tanks run through it, I am starting to wonder. The fuel filter was clogged up and when water comes out if the tail pipes, it blows **** on the ground. Should I go through the trouble of removing the tank or keep using high grade and some sea foam????

 

I would drain it. The hose is right in the middle of bottom of the front of the tank.

 

would that be enough???

 

I don't know how much debris is in your tank , so I can't answer how much is enough.
You have to start somewhere.

 

Thanks! Would the sending unit be rusted up???

 

I have no idea. If the sending unit works, leave it be.

 

what type of debri is your filter trapping? Did your vehicle sit for a long period of time? Alot of times sitting for a long time can accumulate all kinds of crap. If your getting alot of junk, removing and cleaning is the only way. I've found power washing the inside does a great job.

 

If you have no cats and an exhaust system with flowmaster mufflers or the like, you will always get soot in your exhaust and water blowing out the tailpipes on fire over. The air is cold and the exhaust is hot, and therefore you get condensation in the system that either gets trapped in the bottom of your muffler or blown out the back.

As for the tank... I'd get two of those clear plastic filters with paper elements in them that let you see the gas and put one in front of the tank and one in front of the fuel pump at the engine block. Then let the filters work.

If you are worried about water in the system, use dry gas to take care of that.

Draining the tank can help, but many times its not going to completely solve the problem of debris in the fuel system, because all the debris will not drain out, and what doesn't sits on the bottom of the tank, and many times work its way to the sender the completely clogs the system when you refill the tank.
