'57 Beetle fuel tank;

I am getting ready to install a new fuel valve assembly.

I need to know the thread specification so that I can obtain a die tin order to chase the threads which are partially filled filled with corroded aluminum from the previous fuel valve assembly.

Thanks in advance

M18 x 1.0 ?

see this thread especially end of page 1 and page 2 https://www.thesamba.com/vw/forum/viewtopic.php?t=...mp;start=0

several suggestions to use a thread file rather than a die...
