Fuel pressure tester Q's

[paanta]

I've got a cheapo fuel pressure test kit that I haven't used in years, and I suspect it doesn't have the right size fittings (or perhaps they're missing from the bag) for my '91 535i.

Anyone know what size the fuel feed line connection is off the top of their head? AN? NPT?

Thanks!

It's 8mm ID hose with a barb and clamp. all you need is the appropriate size tee, some hose and clamps. There is no port for testing.

Rad. I thought I remembered it screwing in.
