Al, The fuel fill we're using should work ok in place of what you pictured as long as the hose size is ok.
I'm getting ready to install the new trunk latch, I sure hope all goes well. I have to open the hole to 1" and drill 2 mounting holes. I made the locking cam last night, just need to cut to length after lock is in. You can see pics of the lock in the "lock thread.
