[TR] Stromberg plug o-rings

[Bob Peglow]

Thank you for your reply Randall.
Ref. I found said prod. 2-114 was:
I.D 5/8, O.D. 13/16, C.S 3/32 Note also said originals did not like Ethanol.
Since one is only weeping I'd like to find replacements FIRST.
Weather is getting real nice.
I'll take a look at Harbor Freight
Bob
