Default Best way to switch fuels at an event

I don't have a dedicated trailer car, so my question is what's the best way to switch fuels. I'd like to run C16 next year but I would like to be able to drive on pump gas to the event and switch there to save $$$.

What is the best method to switch to race fuel?

I have thought of 2.

1. - Drain gas tank with bolts on bottom of tank on each side for draining into containers at the event (messy, cumbersome, etc..)

2. - Run the fuel pump to drain tank in some fashion (keep the amount in the tank low the so fuel pump doesn't have to do that much (may wear out fuel pump)

Well? Thanks in advance for any advice.

Justin

Take the fuel return hose and drop it in a gas can. Start car and run it till the car dies.

Your pump doesn't do any more then it does during normal idle.

What if you have your pumps set @ 100% all of the time?

Bring another larger pump that you can use to pump your gas out into a can, then prime with the new fuel. re-attach pump on car.

I think they make hose's that drop down into a tank of a car that do just this. I remember looking at one at Gander MT. for some reason.

tom,
I never thought of using the return and running the car, awesome.
should make things easier because I would be able to do the same thing to make sure the fuel has reached the engine before switching maps.

DILLIGAF - I have tried to use a hose that goes into the gas tank, I ran into all kinds of problem trying to get it properly down into the filler neck.

I don't know how this thing works or not. I will ask my dad. I think it pretty much works as a syphon, that you don't have start yourself.

I would think tom's method would work still.

tried one from advance auto, still couldn't get fuel back out of the filler neck...but let me know anyways although I think I will go with the return method.

I don't have a map (UTEC) for C16, but I do have one for 100. I just time my fuel level so I arrive at the track with less than 2 gallons of 95 (a mix I normally run) in the tank, then add 5 or 10 gallons of 101.

Pumping out the existing fuel has never been an option I've considered. Too PITA, and it's easier to do the fuel level timing method. Then again I don't have a tune for C16--if I did I might investigate and use Tom's trick.

manage your fuel prior to the event.
If it means getting a gallon at a time of pump gas during the few days before the event, then so be it.
Make it to the event on fumes. Then fill er up.
