74 spider. Have the tank out and getting it cleaned up. The filler neck hose looks original. But might as well replace it. It's the straight hose, not the newer curved ones.

It seems to be 55-56mm or something between 2-1/8 and 2-1/4 ID. An odd size.

I can find short lengths of 55mm silicone hose for intake coupler of boots. Is silicone a no-no for the filler hose?

nevermind...CA has the 58mm hose...will have to wait until I have a large order.

But my caliper measured the fittings at 55-56mm?

what about VW bus hose? seems to be 57mm diameter and 12cm long?
would that fit?

should be half the price in USA for something like this, methinks
Fuel tank filler hose. Bus 1968-1971

I certainly wouldn't use silicone there.

I guess if it's really 58mm as CA lists....then any standard 2-1/4 hose from any parts house would work. I just assumed Alfa used an odd or proprietary size since my caliper read 55-56mm which is neither 2-1/8 nor 2-1/4.

Silicone is a no-no for fuel. I learned this the hard way!
