Looking to fit a remote filter to my A+ Marina block. What is the filter thread, 13/16 UNF or 3/4 UNF or neither! My thread gauges don't cover these sizes.

Thanks
Tom

thought it was 3/4" unf

That was my understanding too but Matt Lewis Racing reckoned there was also a 13/16th UNF one?

from the Crosland catalogue 5/8" x 18= 5/8unf, I was mistaken, memo to self 'always look it up'

Chris A, just checked and it is 3/4 UNF for the Marina A plus block which takes a GFE 150 oil filter

thanks, my memory isn't so bad then

Chris, this is driving me even more bonkers. The A+ takes a GEF 150 filter according to Daniel Stapleton and that is listed in both 3/4 - 16 unf and 5/8 -18 unf!! I have just measured it and 5/8" thread it is so I am going to go with that. It does go to show it is worth checking as both sizes for the same part number were listed by respected UK filter manufacturers.
