Generator exhaust

The only way I can think of then would be to hook the flex pipe up every time you use it. It has to exhaust way up in the air to prevent killing you or your neighbors with CO.

 

Sometimes I forget that most trucks are about 8ft from the end of their frame. I was thinking like it I were to do it on my truck and typed before thinking it through.

 

A couple of potential problems with an exhaust longer than the OEM recommends are increased backpressure and heat. The back pressure can cause inefficient combustion, which creates more noxious gases. Excess heat can cause premature engine failure or other problems around the exhaust.

If using flex pipe, make sure it is designed for exhaust so it won't leak and can handle the heat.

 

I've got about 8000 hours on the Predator with no problems even with 10-12 extra feet of exhaust pipe. I'm not really all that religious about changing the oil in it either.

That stainless Espar exhaust pipe is some tough stuff too.

 

that what i did with the APU on my previous truck the had stacks up the back.

 

I learned the hard way that the conduit needs to be supported most of the way up. When I first installed it, there was about four feet sticking up after the last clamp. It eventually snapped off right at that clamp just from the occasional tree branch hit I guess.

I picked up the new Honda generator yesterday and gave it an overnight test at home. It's quite a bit louder than the Predator but it was dark and I didn't see it had an Eco throttle switch. I imagine it'll be quieter when it's not running full tilt.

Even running wide open, the fuel lasted almost 10 hours with the regular load of running the A/C, fridge and battery charger. Still have to weld a stub in the muffler to hook up the exhaust stack.

 

My 4' excess conduit broke at the clamp as well. I didn't have it high enough to hit anything. The constant stress broke it, kind of like bending sheet metal back and forth. It was a really clean break, and it was barely hanging on.

 

Got the new Honda installed. Unfortunately, the way the exhaust is pointed means I have to face the control panel toward the cab.

I did have to weld a little stub of conduit into the end of the muffler.
