Gendirect extended run kit for Champion generators.
OK I bought this kit for my Champion 3500/4000 digital inverter genset, tho it should have worked on the non-inverter model too since they have the same fuel cap. This is what I'm talking about. I emailed the seller before hand to check if it would work with my generator and was told that it would.
Well to cut straight to the punch line, after I cleaned up my old outboard gas tank and filled it I set up the hoses as instructed and went over to the genset to try it out. The provided cap is female thread the champion cap is male. All stop. I'm waiting for a Return Authorization.
But before you go let me explain how this kit works, which may or may not give ideas to you DIY people.
1) It has a massive machined aluminum cap, grossly over-built in my opinion.
2) The cap has a threaded hole for a 1/4 in brass tubing connector. One end of the 90 is 1/4 in npt male thread the other female. The male end is threaded into the cap.
3) They provide a 1/4 male quick connect that threads into the the female 90.
4) They provide a 3 foot length of hose, just like what's on the outboard gas tank. One end has a female quick connect and the other a male 1/4 fitting that threads into the 90 on top of the outboard tank.
5) That's just about it for the kit at $140 delivered.
6) They do give you a tiny black plastic cap that you are supposed to plug the vent on the generator tank with. I instantly lost it but found that a couple of inches of 1/4 PVC of tubing with one end heat sealed would work fine.
To operate this system you:
1) Fill both tanks
2) Plug the vent on the genset tank
3) Make sure the vent on the outboard tank is open (mine has a check valve)
And that is it, the closed gas tank pulls gas in and keeps the genset tank full.
My 3500/4000 has run 17 hours on a full, roughly 2.5 gal, tank. That's 6.8 hours per gal or round it down to 6.5. Add 6 gals in the outboard tank and that should give you 56 hours of run time. Tho I would not depend on that without testing. That is in ECO mode.
Since I has a full tank in my outboard tank, there are plenty of fittings down at the hardware store. And I have a tap and die set. I may be be tempted to save myself $140. They don't seem to have an appropriate cap anyway. It would be better to get a bulkhead fitting online for that plastic cap tho since it won't hold a thread as well as their aluminum cap.
