fuel bowl wont drain

[Nitro41]

when i bought the truck it worked fine. i would open the little yellow valve and everything would drain out.

now ill open the valve up all the way and nothing comes out from under the truck. not a drop is spilt. any ideas on whats up with that?

Sounds like the line is plugged somehow.

Pull your filter, if you haven't already. Maybe something the fuel bowl.

Just shootin' in the dark.

you have something plugging the drain, take out the filter and use a q tip to clean around the drain hole inside

mine did that too, with the truck running i QUICKLY opened and closed the valve and it blew out the stuff that had clogged it, shut it off and then drain the rest of the way after draining it clean the bowl really well then put in a new fuel filter and then turn the key on until the pump stops pumping fuel then your good to go

I opened mine and turned the engine over a few times but didn't let it start. Then all the sudden in just poured out..

Do you have the lid off the fuel bowl? Maybe it's not draining 'cuz there's no way for air to displace it. Sorta like how liquid will stay in a straw if you hold your finger on the top of it.

The cap on isn't a problem..I drained mine just yesterday with the cap on. And our 7.3 work truck today with cap still on..if people don't drain it enough it will plug up with junk..trust me just open it and turn it over..once should probably do it but if not a few times and even if it starts for a second it's not gonna hurt anything.

they are purposly designed to be able to drain them without removing the filter, since the gasket should only be used once.

Mine was clogged. With the engine running it didnt clean it out. Also had a lot of sediment at the bottom of the bowl.

I did mine when the hpop was off. I had to remove 1 fuel line to the head, remove the ac bracket and put aside. Stuck wire into the tube and is clean now.


But first try with a metal clothes hanger and run it up the bottom of the pipe to see if you can break any blockage.
