Just what is the purpose of the so called sensor or restrictor in the one line at the pump on the 1997 model of chevy and GMC pickups? I have had nothing but a truck that wanders all over the roadway from day one. Numerous wheel alignments, replacement of ball joints, and tie rod ends and idler arm made no difference. These were all replaced at the recomendation of a Chevy dealership to an ungodly sum of $$$ which made no difference in handling at all. Then today someone tells me there is a sensor of some sort that causes this, and said to simply remove this sensor and have a special hose made for it to cure the problem.
So what gives with this sensor deal? Thanks
