Change fuel filter - drain tank?

[matrophy]

Chilton manual says to drain gas tank before attempting to change fuel filter in 86 720 then remove fuel filter fuse and crank until line is empty. I haven’t looked up in the filter area but can I just pinch the line from the tank shut after emptying the line by cranking with fuse removed ?

You must mean the fuse to the fuel pump. If the pump is off what good does cranking the engine do?

 

 

This is the filter between the tank and the fuel pump????  Yes???

Just pinch the hose on either side of filter to prevent any chance of siphoning.... and replace. Expect some spillage so do outside away from any ignition source.

If the truck has been sitting a while, I would think it's a great time to drain the tank, but no, you don't need to drain it to change a filter.

 

For what it's worth, there are special automotive hose pliers that work like vise grips, but have soft jaws that will not damage the hose.
