Subject: [Chrysler300] Fuel Filling
Overflow
This is a subject we tried to beat to death in a previous forum
thread that may have been a year or two ago, but I'm pretty sure we didn't
reach a conclusion and a solution at that time.
Many of us seemed to be unable to fill our tanks with gas (or that
which passes for gas these days) and have the nozzle automatically shut off as
it should when the tank is full. I and others know this to be a problem on our
Cs and Ds, and as I recall the complaints came in from owners of of several
other years of Letter Cars as well.
An interesting (and ironically telling) facet to the conversation was that
some folks said that they didn't remember having the problem many years back
when their car was near new, but it now has become an issue they can't figure
out. Why should it now be any different than it was?
I think I have finally got the answer. I wish I could take credit, but some
member who saw it on the forum - and whose name I apologize for not
remembering - pointed out the cause which is simultaneously both obscure and
obvious. If you look inside the filler tube, you will see a long metal
stamping attached to the inside of the filler tube. That stamping forms a vent
and that vent must be oriented on the TOP of the filler tube to work
right.
The reason the problem didn't occur on new cars back in the day was that
the installers knew about this quirk and put the tube in correctly. But when
we restore our cars and pull the tank down, we don't notice the feature inside
the tube, and, as in my own case, we may even install the tube back in the car
exactly upside down.
The solution is easy. On cars with a straight filler tube running through a
gasket at the quarter panel and an O-ring at the tank end, you just have to
spin the tube until the vent stamping is at the top. I know this works on the
C, and maybe it does on all years of Letters.
I had a special spanner wedge tool welded up that neatly catches the cap
notches at the top of the filler tube, and in 30 seconds I re-positioned the
orientation of the tube. For those of you who have the same problem, you can
try your own method of rotating the tube if you like, but my offer is to let
anyone use the tool I made if they wish.
I have sent the 2 pound tool off to Bob Porecca in New Jersey to use it
first, and he can cover the shipping to send it on to the next person needing
it and so forth. We'll just keep it travelling around the country to where its
needed. Just let me know if you want it and what car you're going to use it
on, and I'll track it and let you know when it might get to you.
If you want to see photos of the tool, let me know off the forum and I'll
email them to you.
