Fuel Filter Housing Switch won't seat.

[Dozer11B]

Hey guys I was having a hard time starting my '09 for about a month.

After doing some reading and some advice from a knowledgeable buddy we determined that air was getting into the fuel lines. The other day it wouldn't start at all.

Figuring I would go with the cheapest fix, I started poking around the fuel filter area after reading this:

I've got all the manuals downloaded and I can see the three switches on the fuel filter housing.

I pulled the top switch to inspect and now I can't get it seated all the way into the housing, which won't let the vent plug seat. When I tried to start the truck it fired up and then died. Fuel was coming out of the vent plug hole...

Am I babying the switch on top? I didn't want to break it, so I didn't use my man hands...

By top switch do you mean the fuel heater on the top of the filter housing, next to the air bleed petcock? Also I would do away with the stock filter as much of us have done. I played with my stock housing for a while trying to tweak it, and finally realized it was untweakable.
I would look here:

For advice on how to switch filter systems.

After digging through the TM it is the fuel heater. I thought it wasn't seating all the way which was keeping the vent plug from sealing off the vent hole. I just replaced the fuel pressure switch behind the filter and then tried to seat the vent plug and fuel is still coming from the vent hole.


I'm thinking the rubber tip of the vent plug is compressed from age and not sealing correctly. I can't find one online, so I may add a dab of black RTV tomorrow and let it cure for a day. Maybe that will give the old plug enough length to fully plug off the hole.


The fuel is coming out of the top btw.

ETA: Thanks for the links btw. I'll have to look into the fuel filter conversion down the road... Looks like a fun project.
