My fuel lines are pretty rusted and need replacing. I noticed there are three steel lines coming from the tank, but i'm not sure which lines are what. I measured the three of them and I know that the sending (feed) line which goes through the filter is 3/8", the other two are 1/4" and 5/16", can anyone tell me which line is the vapor line and which is the return line?

Also, it appears that my lines are connected to the sending unit via rubber hoses and hose clamps, is this the stock connection? And what is the thing attached to the fourth line coming from the tank? see picture for details

I have the same question - hopefully you will find the info.... One is delivery, one is return, one is vapor and one is..... I just know for sure the first two ha. ha. BUMP

 

5/16 should be return. 3/8 feed. Little line should be vapor canister

Yes stock lines are connected to tank by rubber line and clamps. 4th line is a tank vent and should have a filter thing on end
