fuel pressure dropping over time

allright gents, this is where we're at

i took apart the regulator and found 2 potential issues

this is a "reference style" adapter which means there is a small nipple that can be fed by engine vacuum or blower boost to decrease or increase fuel pressure

i dont need it, it just came with it

per the instructions, i left this barb open, vented to the atmosphere
upon inspection i found a tiny pebble (i think it was a pebble, i pushed it out with some wire and it disappeared)

i cant imagine it did much, but who knows
i got it out and put a vacuum cap on there for now


the second "issue" i found was one of the fittings (the one that feeds the carb, in fact) had more thread engagement then necessary and was protruding into the well of the regulator

it didnt look like it would interfere with anything, but i thought it might cause some issues, so i trimmed that down and reinstalled it


no idea when i get another chance to drive it, but we will see if it did anything
