fuel gauge sender
Ian, where are you getting it? Just curious because some of them are inaccurate.
With that said, I bought a new one with the 3/8" line in case I install new fuel line in the future, I can step up to 3/8". Mine has the return line as well, I just blocked it off for now. I plan on running a return line to the tank and switching fuel filters.
I bought this one:

It seems to be very compatible with my gauge, when it hits empty, it's empty, lol.
I got it here:

It's the eleventh one down on the page.
