Unfortunately the land is pretty much flat. Grade only changes 3ft over all the 63 acres.

If I have to remove water, only way I can do it is to pump from the unfinished large pond to the finished small pond, let it run out the overflow and drain like it would during a flood, out to the ditch at the road...

The best option is to setup the pump with a large fuel tank and let it run. Problem is, it's almost guaranteed someone will steal my pump...

Is there a place on my 225 that I could T off the fuel and hook a hose up to my trash pump?

I have a diesel trash pump...

It shouldn,t be no big deal to tap in the fuel tank on your 225 so if your not handy at plumbing it up maybe you have a friend that,s either a plumber or even a good mechanic that can pipe it up for you.It should only take a couple fittings & hose hook up to do it.

I can do it myself. Do I just T into the hose that runs from the tank to the filter housing?

I know it's supposed to be a steel line that runs underneath, but someone who owned the machine before me put in a hose.

I plan to use the bucket & thumb and drape it over the pump, chain up the pump to that for security.

The trash pump is a 9 HP single cylinder diesel. Right now it has a 2 gallon fuel tank with a hose coming out the bottom. I'm not sure if there s a needle valve somewhere in there or not. I'd hate to drain my 65 gallons of fuel from the 225 onto the ground...

This is the trash pump I have, except mine is a 3" : cgi.ebay.com/HEAVY-DUTY-COMMERCIAL-DIESE...QQrdZ1QQcmdZViewItem

It's an import piece of junk, but it was cheap enough and did it's job last year.

I don't believe it has an injector pump on it. Is it possible to have a gravity fed diesel engine?

It has an injector pump on it if it's a diesel. It might not have a lift pump though.

You will need to provide a way for it to recirculate the injector bypass fuel if it has a return line to the small tank. Probably would be ok just to return it into the fuel line from the excavator as long as there is no air leak into the system on the suction side and you purge the long line from tank to the pump completely. All in all, it might be simpler to use a barrel/skid tank that you can move with the excavator to keep the fuel line short and simple.

If you can put a very short suction on the pump and mount it/lift it with the excavator bucket, you can easily keep the pump very close to the water level so it has to lift very little. You want a pump mostly pushing water, not sucking it if at all possible.

It can be hard to keep a pump like that near the water if you have to haul it there by hand through the muck along the waterline. So mostly folks have quite a long suction hose on them and keep the pump up on high ground which cuts the output, causes cavitation damage etc.

I know all about that. This picture shows the pallets I horsed the pump up & down everytime I went to the lot to pump:

BTW, I eventually go that pond much deeper:

The water is at least 10ft deep in that last picture...

If your going to tee off the line to the 225 then after the tee line going to the backhoe engine put a shutoff in the line so it doesn,t suck fuel out of the fuel system in the backhoe engine. I,m guessing your 225 has either a 3160 V-8 in it or a 3208 V-8 engine.

3208

I might just find a tank instead of messing with the 225's fuel system...

Sounds like a better idea to me to get separate tank if you can and if you need the 225 you can move it then and not bother the pump.

Ok, the trash pump does have an injector pump, and a scavenger line going back to the tank.

I have a ~18 gallon tank I can use for the new fuel tank. I figure I can use the existing 2 gallon tank on the pump to catch the unused fuel?

What is the ratio do you think of the fuel used to that which is not?

If I go though 18 gallons of fuel, how much unused fuel should I expect in the 2 gallon tank?
