Can anyone tell me what the size of the fuel tank drain plug is?
I need to order a fluid bolt and a banjo fitting for it but I am not ready to pull it out of the tank yet.
Thanks.

Part number wise, it is 22MM by 1.0 pitch.

No it's 22mm with 1.5mm pitch for steel tanks and 16mm with 1.5mm pitch for later cars with aluminium tank.

Thanks Guys, that's exactly what I need.

The only problem is that isn't a very common part. It's going to be difficult to find.

Yup, that's what I thought. The two largest suppliers of metric fasteners don't carry anything that large.

OK, Fredrick, where'd ya' get the parts? Probably in a Euro Home Depot, right?

Help me! Excuse me, I have to go bang my head on the wall now!

I bought the parts from a tractor parts supplier here in Sweden! I paid $20 for the parts and almost the same for the shipping!

I think you can find the parts here also. Link

I used a AN10 hose with 1/2" inner diameter from Earls.

The 22mm size of the fluid/hollow bolt is the problem.
It is a very large size for us here in the US.
The largest I can find is 16mm.

I can't find anyone that even has a reducer to go down from 22mm to 12 or 10mm.

The 12 or 10mm hollow bolt is very common in Earl's or Aeroquip.

I can't even make my own because I don't have taps and dies 22mm.

This is the biggest problem. Once I can reduce the 22mm it will be a piece of cake!

Doug 22mm = aprox 3/4" try Mc master car for adapters to NPT. or you can get a 3/4 NPT tap and tap out the tank it could be 1" ? if you have the 22mm Plug .. take it drill it out to 1/2 NPT and your done. If your car flows more then 1/2 NPT ( ID ) your going to need 2 gas tanks ...LOL or if you want I'll drill it and tap it for you in my shop in about 2 minutes.

22mm = .866".

Drilling it out to npt is the next best alternative I agree. Simplest is to use a 22-1.5 to 12mm-1.5 reducer fitting, put a banjo to -6 and a fluid bolt/hollow bolt on it.

I still have to pull the plug out and see what the Detomaso's gave me to work with. The bushing needs some meat to go to 3/4npt. No sense in leaving it too thin, with a brass to steel factory fitting soldered in there.

It is for a return line for the EFI. A -6 hose is all it needs.

The question is how to get for point "A" to point "B" by the simplest route.

The tank is in the car and will not be coming out anytime soon. At least that is plan A.

Thanks for the suggestions.
