Stop fuel spills- filler neck modification

[Mach1 Driver]

Hey Terry. (I'm a little late to the party...) How has this modification worked in your car? Success?

I assume you are asking Horseplay-Terry, and not Mach1 Driver-Terry? I haven't seen any updates from Horseplay, but mine works just fine and the best modification I ever made to the car. I would cuss the damn thing every time I filled-up, but now its no problem.
I don't really know if I still get fuel sloshing out the back when accelerating with a full tank. I don't think so, but I intend to get rid of the carb and go to EFI. I will get a new tank with the pump in it. It will have the fuel line, return, and a separate vent, then I will use a non-vented sealed cap and that will be the last of that problem, if it still exists.

TERRY will never drive his car to find out

Ha Ha. Yes, my car failed yet again to make it to the street this past season so no actual results can be fairly given on the filler neck mod. I can tell you, however, that is now matches millions of other set-ups on cars that get filled up routinely at the pump (much like my own daily drivers) so I don't expect any issues.
