GM fuel regulator bolt size
I'm trying to figure out what size the bolts holding the upper and lower halves of the TPI fuel regulator are. Them seem to be a weird size around 3.5mm x.6 threads. Might be SAE but can't find a match locally to verify what GM used on it.. A size and source would be greatly appreciated.
