Changing from Pump Gas to Race or E85

For those of you changing between types of gas how are you draining the one type and switch to the other? I want to run pump gas on the street and race gas at the track but from what I heard it is a pain to get the fuel out of the tank. Someone told me that there is a easy way to do it if you have DSX Aux Fuel pump I am considering this route but I don't think most people switching back and forth have this. Or are you just run the tank low and switching with a mix of gases? Or??

Curious how people are dealing with this? Thanks for the input.

Probably going to have to purchase HP tuners and have two tunes as I do.

Yep, I got the idea from reading your other posts. I have the HP tuners. How are you changing between pump and race gas?

Is there a way to turn the pump on continuously? I used it to drain once and could only find the option to prime which only runs the pump 2-3 seconds. Luckily I only had 1.5 gallon to run!

I used to just run mine down to below an 1/8 on 93 and dump in the MS109, change the tune and your good to go.

For E85, I figured that you could just switch to e85 whenever you feel like it. The tune will automatically adjust based on the ethanol content%...with the most power coming as close to e85 as possible.

With race fuel, I hadn't thought about needing a different tune...@laynlo, so you just switch the tune for track and street?
