1968 Plymouth Valiant First Gen HEMI

Now I had to do something with the fill pipe. The factory fill pipe has a piece of metal that runs from below the end of the pipe to almost the top of the pipe. When filling the tank this acts as an internal vent so when the tank is full and fuel runs up the bottom side of the pipe (and hopefully shuts off the pump). The part above the divider vents and allows the gas in the lower half of the pipe to go back down into the tank instead of spitting out on to the side of the car and person filling the tank.

When I modified the pipe I lost that feature. Fortunately I’ve been thru this before and knew a fix was to run a ½” fuel line from the top of the tank (slightly above the end of the fill pipe in the gas tank) to the top of the fill pipe (the same system some of the old Jeep Wagoneers’ used).



Putting a fitting for the ½” fuel line in the tank was pretty straight forward as where I located it was a flat area. I used copper washers on either side of the fittings to seal it. Because the fill pipe goes in at an angle the fitting is above the pipe’s end.

In order to get the fitting at the top of the fill pipe to seal I needed a flat spot in the pipe. After the hole for the fitting was drilled I used a ¼” thick washer/spacer I had laying around on the inside of the pipe, ran a bolt thru it and used another odds and ends piece with a flat surface I had in the drawer, tightening the bolt gave me the flat spot I needed for the washers to seal.

If I still had access to a pipe bender I probably would have just bent up a new metal fill pipe but fuel fill hose for a 97-80 Ford F150 gave me the bends I needed to mate the filler neck to the fill pipe (though it had to be extended a bit). With a little tweaking I was also able to also use the original tank vent. It’s not beautiful but then neither was the stock fill pipe and it is functional.

I like having a set of tools with me so a tool box was added to the trunk where the battery used to sit. I don’t like a tool box that slides around all over the trunk so I used a pair of Jeep hood hold downs on each end to hold it in place. I like this setup as it allows me to easily move the tool box between my different vehicles.

I added a spare tire hold down for the spare that’s the same height as the rear tires. Basically it’s done but I’ll probably be adding a latch for the hatch cover to keep it from rattling, but that’s a project for another day.

When all was said and done I have a functional trunk and new gas tank. Overall I’m happy with the way the trunk turned out (I’ll be happier when it’s all painted body color).
