might not be the same problem,but mine ran good in winter then last week with 85 temps it would run anywhere from 20mins to 45 mins before it would stop. fuel pump with coupon code at advance auto was $40. might be worth a try

Here is what I received from Thor.

I have not crawled under the MH to figure it all out, but my first thought is how am I going to mount this, and where am I going to mount this? The kit does not come with any mounting hardware or any stand-offs. What Thor sent me is designed to be attached to an existing radiator.

Disappointed is the only word that comes to mind.

Wow!

I fail to understand how that is going to cool the fuel. Without a fan source, it's going to eventually reach ambient temperature (bad). Ambient temps near that genset are going to be well over 100 degrees with it running.

There is a big engineering fail here. Coolers work because of a difference in ambient temperature at the fins (cooler) and the fluid that goes through them (hot). In this case, the fuel is around ambient temperature - worst case. Someone measure the temperature of gasoline in your tank when ambient is 90 degrees....

Just got done sending Scott a nasty email. What they sent me is a complete PoS. Here is what they should have sent me.

Cooler Link
This cooler has a fan, and comes with the necessary fittings, only thing missing is the hose clamp to secure brass fitting to the fuel supply hose. This cooler also comes with the stand-off mount which will allow you to secure the cooler to something.

Would not there be an increased demand on the fuel pump due to more distance to pull the fuel? I agree with other posters that cooling fuel with this little unit which will be in the same heat zone as the genset is ... well ... just a fantasy fix.

My advice to the Thor "engineer": design an air handling system to pull outside air across the genset then exhaust it to the outside. Why is Thor avoiding the obvious?

I did get a return e-mail from Scott and he needs my tech to call him. But he says he has the parts ready to ship but needs authorization from my tech. We are leaving tomorrow for four days. The time difference is working either against us or for us depending on what happens with the powers that be. I'll keep an eye on the thread and my e-mails while I'm gone. Please posting.

Sure, but remember they put these gensets in 32' RVs and 45' RVs. Also the generators really don't draw that much fuel. As long as the pump will prime, it should do fine.

The cooler with a fan makes more sense to me, but it's going to be all about where they mount it. Also - the only *truely functional* fuel coolers I've seen are water cooled. I've never seen one installed on a vehicle (other than a diesel) that was air cooled...

You guys are gunnea pigs.

I agree.. Apparently they put too much generator in too little space it it's going to draw from under the RV, where the pavement is busy giving off massive heat.... I'd vent that thing from the side and stick a high-volume electric fan on it that is relay'd the the generator being on. Insulate the fuel pump. Insulate the fuel lines.

Scott Harris from Thor called me twice today. Looks like there is a new plan. Guessing my email I sent, and the points made in it did not fall completely on deaf ears. However, Thor's new plan, while it makes more sense, is still the hard way to do something.

The new plan is for me to mount the cooler they sent me on the front of the MH, which will allow better air flow over the cooler. However, the downside to this, is that I now have to extend the fuel line all the way to the front of MH, then return the fuel line all the way back to the generator.

Scott did send me a photo of how they did this to the MH located in Arkansas.

Scott did acknowledge that the cooler with the fan was a better solution to the problem than what they sent me. However, he said that since this solution is what they came up with, they, Thor would prefer if I did it their way in lieu of the way I proposed.

IF someone needs to fix this problem, and is not going to involve Thor, use the fan that I linked. It will take you a lot less time, and I think will work better.

cb1000rider · 06-06-2013, 01:05 PM

My recommendation (if you're not going to involve Thor) - before you put a cooler in an area that doesn't cool or extend fuel lines and expose them to more heat - simply slip lengths of radiator hose over that fuel line (for insulation) - or use a thermal insulator (you see it on the picture above, just before the fuel line gets to the cooler).
And insulate the fuel pump....

It'll be interesting to see how this works. The fact that they're sending coolers to be placed in high heat areas with no air flow shows me that someone isn't thinking clearly.

Moonrover · 06-06-2013, 01:17 PM

Holy sheet !!! Now they want gasoline to be stuck up in front of the radiator where it is the first target for puncturing during a front end collision, or even rock damage.

I hate to be so darned negative on these "engineered" fixes, but ... man ... Is Thor willing to put all this recommended reworking in writing? Massive law suits have come from automakers not adequately shielding fuel tanks from potential ruptures. Now Thor suggests this? <sigh>

Hermosa · 06-06-2013, 01:29 PM

I talked to Bill Sauer today, they are sending me the wrap and heat shield. I am going to crawl under the coach this wekeend and measure out a new enclosure tht will allow some air flow around the front and inside of the genny, then mount a 12v fan on the front of it, pushing air through the area. I played witha 12v fan last night that I picked up from Auto Zone, it moves a lot of air. I will buy a better quality fan for the installation and put a switch on it somewhere near the dash, I think this is a better plan than putting a heat shield on and still having the hot air not circulating.

Bravo!

Logic and common sense all in one package.

Harlee79 · 06-06-2013, 02:22 PM

I'm at a loss of words.. Moving flowing gasoline to the very front of the vehicle in a very vulnerable point to solve a heating issue hardly seems like a safe solution. Colision, rocks or any debris that might come through those wide slots in the front end could cause a major fire/explosion. I understand the engine fuel line is running to the engine but they don't rout that in front of the radiator.
