Probably depends on how the last person hooked it up but my sight of it looks like the lower one feeds the main tank. I got rained out while working out my problem but did discover that my fuel pump was sending gas to the carb much stronger (Pulsating stronger) when I ran a direct line into a gas container in front of the coach. Once I rehooked everything back to original my idling was worse and I stalled out again. My coach ran fine until I depleted the gas in the gas container. I got an idea from another member on line/phone discussion to bypass the switch/valve and see if the main tank would supply the gas needed by directly bypassing the valve. I couldn't get that far (rain). If the switch is properly installed the lower inlet looks like it goes to main tank. Also, I am slightly perplexed as to why there is so many fuel lines for each tank. Is one for the gas delivery and the other for the vapor cannister? Where two line T together to feed the second connection on the vapor cannister?? I obviously know one line goes directly to the carb (vapor line to cannister). Thanks gentlemen I feel like I might be getting somewhere NOW!
