Just alittle reminder, change them before they cause a headache. My 5er is now 6 years old. I had genie problems last Oct., and thought it was a battery problem causing it. Well, because I store the trailer at GDS, I went the whole last season running my back-up honda 3000. I finally brought it back to North county, determined to correct the issue. I just had changed to 2 6v. batts at the beggining of last season, so I thought it was related or an electrical issue.
To make a long story short, I pulled the tank, and removed the ill installed rubber fuel lines, and old fuel, which I found two spots where the hose was cracked on the top side, along the frame, which is why I didn't think much of it, because I didn't see any fuel stains or drips. The Genie was sucking air instead of fuel.
So I installed a new metal line along the whole run of the trailer,instead of hose, and replaced short sections at each end to include an inline filter. Drained the tank, and got it all back together. Sometimes overlooking the little things can cause plenty of trouble. I didn't see any initial indication that the lines were deteriorated, so I overlooked it. I feel silly for admitting it, but I should have just changed them when I baught it 3 years ago. Afterwords, It started right up once it was primed.
I hope nobody rags me too hard, I just thought it would be a good reminder to check the hoses out before ya start the season and also store out there too. I learned the hard way, good luck..
