[tech] need help! Car bucking on the hwy

[amalventano at sc.rr.com (Allyn)]

actually, thats line is in the return to tank path, and if it rots off and 
this results in fuel cut, you have both a rotted line and a faulty transfer 
pump. when the xfer pump goes bad, the reservoir ends up sucking fuel 
through the xfer pump as well as that line, as opposed to the normal 
operation where the transfer pump feeds the reservoir and the overflow goes 
back to the tank. this is actually why that rubber line is present - it 
allows the car to run with a faulty xfer pump.
