mine were 3/4 or 13/16 depending on what style i get.
well. i can say my truck was always a daily driver, and the reason i always used efi. these new efi setups can be awesome, or a trainwreck....by far mostly awesome though.
and for when i wanted to get crazy off road...i really really needed efi, because my favorite places to go carbs were an absolute joke. sure they would run sort of....
sort of.
the system your going to i am not so sure of, as i have seen or rather been hearing of issues here with it locally. fi tech right? and back order being par for issues. one car is sitting in grayling after it quit, and another run great for a week and quit. its been back and forth several times and they went back to a carb for now. the pumps work good but the computers seemed to have croaked, one was on a passthru and the laptop fawked up and the other just went black going down the road.
theres others and no issues at all. and when they work, they all work awesome. i am guessing that there was bad potting and corrosion or something.... nice thing is, for the money, you can just carry a spare.
i thought these would drive down the costs of the eec stuff but it hasnt yet, so i guess your winning either way.
all things shake out in the end generally i guess.
