    I followed rbarrios instructions on how to replace the fuel pump. I kept the old pump and just replaced the fuel sending unit with an AC Delco sending unit. I have an 05 EXT TB.

    OEM Issues
    Just recently, my computer started tripping codes, saying the air ride pump is in trouble. This was in reality no shock to me, since it'd been having some serious starting problems for most of the winter, particularly when it got cold out. (Cold up here means near or below zero) :coffee...
