I have a March 1973 FJ40 model and two different carb rebuild kits are available from GP Sorensen. My carb tag is missing and I need to figure out which kit is correct. Looks like the only difference between the two is the length of accelerator pump. Anyone know which is correct for my carb: short or longer pump? Attached photo shows what I've got for options...and thanks to previous owner, the carb was off engine and included a Keyster rebuild kit. I used this kit and have major issues with the AC pump. I'm thinking it came with the wrong kit (AC pump was too long) and it requires the shorter AC pump. Anyone?
