External Fuel Fill

Challenger outside fuel fill

An external fill can prevent fuel spills inside your Challenger.

Fuel tank adapter

An adapter constructed of
1 1/2" tubing for the fuel - 5/8" tubing for the vent and a regular fuel hose barb.

Cutting the fuel tank

Cutting the fuel tank to accept the adapter.

Fitting the adapter

Fitting the adapter to the tank.

Fiberglassing the adapter

About 4 rivets and a little epoxy is all it takes to secure to tank. 

Plumbing the fuel fill lines

After a little plumbing, it's done.  No more fuel spills inside the plane.

 

Note:  Fiber Glass will not stick to the smooth plastic surface of the tank.
I ended up using epoxy instead.  Heavy sanding with a coarse paper is required.
