Would anyone have an FL inlet nipple handy that could provide a couple dimensions - the nipple ID and the OD at the threads. If you would have the same dimensions for a UL nipple I'd also like to know that. Thank you.
These measurements are from a Colony part for an FL, but may suffice. I.D. is 1.555" The O.D. of the threads (of the end that goes into the head) is 1.743". Sorry, but I don't have a UL nipple to measure.
