[QUOTE=BBQGUY;1271530]Could be several issues.
Verify you are using the large diameter line as the EVAP line. The smaller is the fuel line.
Test the rear fuel pump: Connect a short line to the discharge of the fuel pump, do you get fuel when you turn the pump on?
If No; loosen the fuel cap to the tank and try again.
If No again, disconnect the fuel line from the input side of the rear pump and blow air in the line to the tank. You should hear the air enter the tank. If no report back.
Thanks BBQGUY! The Gen set has the 5/16 fuel barb labeled feed line and the 1/4 " barb labeled return line. Since my TH is prewired and plumbed for an Onan Cummngs Gen set I automatically plugged the larger hose to the feed line and the smaller to the return. As stated, I couldn't get the Gen set to prime with this configuration. After consulting with the tech at the dealership I decided to switch the hoses. The Gen set immediately primed and the unit cranked right up. The problem now is the return line to the tank is apparently plumbed wrong because gasoline is pouring out of what looks like a 3/4" vent hose. The vent hose comes out of a separate small tank that is beside the actual fuel tank. I can't find a blueprint or a drawing of the refueling station and Gen set tank and lines anywhere on line. Without a drawing to go by I don't know if the fuel lines are plumbed correctly or not. Suggestions greatly appreciated. I would really like to figure this out on my own so I don't have to do without my camper for weeks while it sits in line at the dealer waiting to be worked on, even though it is brand new and under factory warranty.
BTW, I don't think I have a rear fuel pump, except for the pump that is used for my refueling nozzle.
