going threw the over fueling now with our 190E, first you have to find the posts that are on setting the value of the EHA that is the most important issue with that item, you cant just put one on and think it is ok. find those posts and set its electrical value first then move on from there. JNT also look toward the fuel pressure regulator, this is the one I am asking Doc about at this moment, have not gotten an answer yet. JNT
