fuel burn rate at Idle?

That's what I've heard through out the years, 1 gph.

 

BTW, I noticed this was your first post. Welcome Wulfman76.

 

Hello Wulfman76 and Welcome

 

I have a 3406E Cat (Same as C-15) and I figure idle time at 1.5 gals per hour. I am guessing you are going to be idling up to run the pump? When I idle I bump the rpms to about 800 to keep oil flowing smoothly and keep the pressure up.

 

if a 20hp engine will do the job whats the purpose of the truck? Just set it up on a small trailer tow it behind a car. Plates are cheaper!

 

Refers typically have a 2 or 3 cylinder diesel. You may try an APU engine as well. Mine is a 2 cyl kubota at 14 hp. Burns about 1 1/2 pints of fuel an hour.

 

You can also try an outboard engine for a boat. I know it sounds funny, but they come in any size you could need for a project like this. From three horsepower to 400 horsepower... Now, here's the thing....if you wreck the bottom of the motor into something, it's considered junk and immediately sent to a junkyard! You can often find wrecked outboards with perfectly running engines...figure out how much horsepower you want, then go find an outboard with quite a bit more than that, so it's not redlined the whole time. It's a watercooled engine, so you'll have to hook it up to a radiator, etc, but you could tap into the cooling system for the truck engine just like an apu would, so the engine block is already warm when you drive off!

 

Thats a pretty good idea!

Before APU's everyone figured an engine used 1gph, after APU's they raised it to 1.5gph to make it seem like a good idea to buy one. My mechanical motor uses 1gph, the newer electronic motors is less than that.
