tbi regulator

561-61500 is the part number Jegs lists, but is there something that would be a lesser of a pain in the *** to adjust? This looks like you have to take it apart each time you want to put a screwdriver to it. I understand I won't be messin with it too much, but just the initial setup.

Is this the right one, and/or is there a better one?

ya, its a pain in the *** . but its the only way unless you get a blockoff plate and take the internal regulator out, and put an external regulator and fuel pressure gauge on the return line.

by the way, what are your mods. do you really need a afpr. Are you lean now. or rich. Do you know. For some, its best to just leave that alone. and mod other places. i dont know what your case/knowledge is.

Run the car to operating temp and then shut it off and take out one of ur spark plugs (probably one on the driver side since there easy to get too) and if it looks black then ur rich. I forget lean, i think it looks real tan if ur lean. I might be wrong though.

i think white if you are lean. "ithink"

or you could trust your o2 sensor and read the tech article on how to do that.
