Fuel tank selector 1972 C20

[jojomiamia]

Hi guys,

I have a 1972 C20 Custom Camper which is fitted with a dual fuel tank (NL2 option)

When I'm selecting the aux tank, there's a big fuel smell in the cabin, which means the fuel tank selector upper part may be cracked.

For the time being, I have no time to do the trouble shooting, but I'm quite sure I will have to change the fuel selector.

Do you guys know where I could find the exact part ?

Thanks,
