Also, why are the two holes on the side of the tank different sizes?
Is there somewhere I can go to view a diagram of how it is supposed to look?
Sorry for the simpleton questions?
Thanks in advance
I ran into this today and this is how I got going again. Note, this starts with the fuel-tank empty.
01..From the tank, I removed the broken line, its attached fuel filter and the double-ended nipple
02..I removed the hose-remnant from the lower primer-fitting and cleaned the fitting
03..I measured a length of new fuel-line to fit from the tank-hole down to the bottom of the tank (lying flat) and took away 1/8" from the length to account for the nipple
04..I cut another length of fuel-line with the tip at a sharp diagonal for threading into the tank through the smaller hole....I left this section about 9" long because I would be trimming it back later.
05..I pushed the diagonally-cut hose-end into the smaller tank opening until I could grab the tip with a set of needle-nose pliers.
06..I pulled the new hose into the tank until I had about 1" pulled out past the filler-port
07..I then cut the diagonal section off, removing all the section that had been crimped by my pliers and slipped the double-ended nipple into that section - where the nipple would be in the tank connecting the external section of hose I'd just pulled in to the section designed to lie inside the tank and draw fuel.
08..I then too the section I cut in step #03 and slipped one end onto the double-ended nipple and attached the fuel-filter to the other end
09..I fed the filter and hose into the tank, ensuring it was not kinked and was lying flat against the tank bottom
10..I then used my needle-nose pliers to pull the exterior section of hose I inserted into the tank in #5 CAREFULLY back out of the tank ( gripping the hose about 3" above where it goes into the tank to avoid damage to part of the line that will remain) until the backside of the connecting nipple was flush against the top of the tank. I again check to make sure my filter/intake is flush against the bottom of the tank.
11..I then measure the length of the fuel line I just finished drawing back to make sure I have enough to reach the lower fitting at the primer-bulb and I add about 1/2" extra to account for flex. I then cut away the excess including the crimped section I had my needlenose on.
12..I reattach the line to the lower primer-fitting
At this point, I decided to also replace the return-line that leads to the larger hole and attaches to the UPPER primer-bulb fitting. The installation was exactly as steps #4 and #5 above, and cut the line sticking about 1/2" sticking down inside the tank.
I cleaned up, put away my tools, rinsed out the tank with fuel, fulled up and I was back in business for the day.
This may not be the exact "approved" technique, but it did get me going again :-)
I have seen it posted elsewhere that on some models, the intake and exhaust for the primer bulb are reversed. I tested for this by placing my thumb over one fitting and pumping the primer bulb. If it "sucks" its the intake and gets the line with the fuel-filter. If it does the opposite - its the return and gets the return-line that connects to the larger of the two fuel-line hoses.
