Fuel Cap

[Peggy & Ed McStay]

Hi------ have been reading your post on the trouble you are having
getting a fuel cap. I just went out to my 83 35foot bluebird and pulled
the fuel cap off. with a thread gauge the threads are 11 1/2 per inch.
that is with a 2 inch fuel pipe opening. you say that yours is 3 inch.
according to the chart that iam using if your fuel pipe opening is 3
inch then the threads per inch will be 8. hope this helps you some.
good luck
