So I have an FSM for my 88 runner. There are a ton of hoses on the 22re...at least to me. I blew a small hose which goes from the bottom of the fuel plenum to I think the head. It is 'U' shapped and about 8" long, approx 1/2" OD &1/4" ID. I can't find it on my FSM.What is this hose? bypass line maybe? thanks for the help!
