That infernal fuel filter elbow - stunned_monkey - 21 Oct 2019
I've sourced and replaced this part only once and never identified what it actually is. On that occasion it was frozen solid to the hard line and had to be cut off. I sent off what I had and back came a new one.
Number 28

The hard line fittings on the car are all 8L - which is an M14x1.5 thread, and that's what you'll find up the fuel filter's bum too.
So why is it a taper thread? You don't get metric taper threads...! Nor do you get 17tpi imperial threads, which would be "close enough".
Or a better question might be: Why is it some mashed-in pipe fitting, and not a perfectly commonplace metric thread like the rest of the car? That would mean any fuel filter of this reference could be used, not just the ones with machine aluminium threads at the base.
Just when I thought DeLorean had thrown its last curveball....

Is it a British Pipe Thread Taper size? (BSPT)
There are various lookup tables but this is the first one google throws up:

It could perhaps be a 1/4 BSPT thread or similar?

I can't see any with 17TPI, can you?

Any chance it’s 18TPI? If so it could be 1/4 NPT? We used to have lots of “fun” with US spec. equipment when I worked for an American company.
