Curious as to what you used for the fuel cap grommet? That looks pretty much just like mine which is a toilet bowel to stool rubber seal.

I believe I used the same thing, the grommet seems to look and work just fine.

Fill neck finished, also got the dash and glovebox covered today.

Next up make up the glovebox door.

You need a ground strap from fuel inlet to chassis....

I got into this very discussion about this point with a friend, can you give me your reason / reasons why you need a ground strap?

Thanks.

Same reason you do it on a boat (and there are regs for boats but I don't think there are for cars!). If you have a build up of static electricity, from the gas flowing in to the tank, and you don't have a path from the tank filler to the ground circuit of the car, and the stars align properly, then you can get a nasty spark, which you don't want. The general rule for boats is that a metal fuel fill system and metal fuel tank have to have less than 1 ohm resistance to the system ground. But, if you're feeling lucky, feel free to disregard this.

... and that's probably because there are a heckuva lot more fiberglass boats than there are fiberglass cars.

... so let's go to the videotape. In this vid, the woman created the buildup of static electricity by getting back in to her car, maybe shuffling her butt around a bit, and with just the right fabrics involved, like wool pants, and then she touches the metal gas pump. On a non-grounded fuel inlet system, the rushing fuel itself can create the build up of electrons, and when the build up reaches the magic point, the electrons will jump. If the fuel inlet system is bonded to ground, the electrons instead will slowly dissipate through the system. And this is why you should never get back in your car and wait for the pump to click off.
