Getting gasoline in carb w/o using the tank

Not sure if this is in the right section... but here we go.

I'm trying to start up my KZ440 to make sure she runs before I start taking her apart. The thing is, the inside of the tank is dirty and rusty and though I have a POR-15 tank sealer kit, I don't want to have to wait 5 days (the time period it's supposed to sit after sealing) before I start her up. Everything is ready to go, I just need a way to get gasoline in the carburetor without having to put it in the tank and having to re-drain the tank/ clog up the carb with the gunk in the tank.

Any suggestions on how to go about this?
 
not quite sure... there is no fuel pump on my KZ440 but there were two lines coming out of the petcock when I got it... the one that wasn't the fuel line just attached at this random spot at the carb. Could it be there if either

a) there was a fuel pump on it when it was stock
or (b) if you want to put a fuel pump?

Because now that I dont think that a vacuum line would be needed without a fuel pump.
 
That random one is a vacuum port, which means you should have a position on your petcock for Prime as well as run. the run position relies on a vacuum signal, but the prime doesn't. Set it to prime, and you should have fuel, vacuum signal or not.
 
Brother SparkE a lot of petcocks have a diaphragm in the petcock, does your petcock have only the fuel line fitting or does it have a square on the back with a fitting? I believe it should have the square on the back with the fitting which will be for your vacuum hose. If you just want to start the engine to make sure it runs you can just plug the vacuum line and fuel the carburetors to start it.

Like Brother Pawn said you can just gravity feed the carburetors with a tank, I use a riding lawnmower tank when I test start an engine, and once you get your tank clean use prime to fill the carburetors like Brother Roadrash said.
 
Plug the vacuum lines if you use a remote tank or it will run like crap.

I made a remote tank out of some PVC pipe and some brass fittings. Hangs from the rafters, doesn't hold much fuel.
 
I rigged up a little test-run fuel tank like so:

It holds about a quart of fuel. I have an extra one if you want it. $10.
 
Actually got an alright water-bottle tank setup, works well enough for the job. Thanks for the offer though
 
sparkE, how did you connect the fuel line to the water bottle? I was going to do that, but I couldn't figure out how to connect them without leaks.
 
well, I won't say mine didn't leak a bit, but it worked out alright.

I first found an empty Publix/ Zephyrhills plastic water bottle, then drilled out the cap just a little bit smaller than the size of my fuel line. I then shoved the fuel line into the hole, and there was a pretty tight seal, but like I said, it still leaked a bit. To get the gas into the bottle, I cut a small flap in the bottom on the bottle ( the bottle is upside down now), then inserted the nozzle of my gas can into it and poured some in. Then I taped up the flap with some good ol' duct tape.

Worked well enough for the job, very crude though. I did only need it once!
