May 22, 2012 - With the tank back in, it's time to sort out the spitting fuel problem.
That's what led to the fireball at the track. I probably should have put some baffling inside the filler neck to avoid any splashes, but instead I decided to borrow yet another Miata part.
The filler on a Miata has a spring-loaded flap in it. Perfect. I cut one out of a Miata filler and welded it into the MG neck, just below the cap. There are two small vents on each side that act as drains and a place for air to escape when you're filling up. They're usually attached to a separate pipe, but I decided to just let them go into the main filler neck. There's a small chance of some splashing through them, but it's going to take some real effort to make that happen. I think it'll be a decent solution, and it's invisible.
As an added bonus, the MG now looks like a modern car that drinks unleaded when you unscrew the fuel cap.
