clogged fuel system

whats a good way to clean the system? drop the tank and clean it all out? blow air through the system with a compressor? i got a clog some where behind the fuel pump. also have duel tanks. the truck is an 86 f250 4x4 with a 351w.

I would drop the tank and drain it completely. You may find it's rusted through on the top where it lays against the frame crossmember, a common problem. You are on the right track about cleaning or replacing the tank and blowing the lines out.

so it is ok to blow air through the system. do i do it from the pump back towards the tanks? i will check to see if the tank is rusted out though.

I would suggest taking the tank to a rad shop and having them boil it out and relining it if the tank is not too rusty. If you don't have a rad shop nearby, you can buy new ones pretty cheap too.
