Swapping from 93 to 116 Octane - best way to get all the old 93 out
 
Hey guys! Haven't been on in a while - the mach is still running great. I have a question because I just got a tune for some Fuse 116, but I was curious what the best, easiest, and cleanest way was, to get all the 93 out of the tank so i can put some race gas in.

I read you cannot siphon because of a 1-way valve in the filler neck.

The next option is disconnecting the fuel line at the rail and bumping the key, but the fuel pump will stop after a second or two, correct? That would take an hour!

I am just below 1/4 tank, so there isn't that much fuel in there. Any advice?

I've used a product called the gas tapper and works pretty well.

you can also get a tune that keeps the pump running with the key forward to pump it out of a fuel line

How? I don't think you can shove a hose down into the tank. There's that one way valve / screen in the way.

The product has a more firm tube you insert first which keeps the valve open. Then you insert the smaller more flexible hose down into the fuel level.
All sorts of videos are out there showing how it's used on modern vehicles that have an anti syphon/rollover valve

It's pretty slick. i first used it to drain my stock tank prior to installing an upgraded tank from Glenn's performance.

Sweet! It's on my Amazon list for when I'm looking to buy myself something for the garage! :D
