I used my stock fuel pump too with the sock on there for filtration and hooked it up to my cars battery. It takes a good 10-15 minutes for a full tank. I would suggest finding a stock diesel fuel pump that does a lot more LPH and it will be a lot faster.

As for tuning in the injectors, I meant that yes, if you're tank isn't completely empty but that you've driven it enough with the empty light on, it will be fine if you have a little bit of gas in your tank. 1/4 gallon of pump is not a big deal when you're putting 12.5 gallons of e85 in your tank. Is it best to completely drain it? Yes, but I can almost gurantee that your tune would be the same either way you do it. E85 requires 30% more fuel than pump.

As for the drum. I got it at wal mart and made sure it had a good seal on the cap. I would also reccomend putting the drum on some 2x4's or something and not on concrete. Ethanol will soak up any water it can that's in the air, and I've seen it happen from condensation from sitting it on the ground.

Good luck, you should like the new tunes!

 

As for the injectors, here's a nify chart I found a while back for e85 and injector sizing. You want to match up your injector with the max size turbo you want to get (lbs/min) and I'd add a little cushion.

This chart is assuming 43.5 base fuel pressure.

Ooh awesome info, thanks for that!

 

east orange has a e85 station.. its called power gas. yes they dont speak good english but who cares its not like your having a conversation with them. its 2.47 there as of last wednesday. also there is a station in Hamiliton nj but im not sure of the name.. I filled up at valero yesterday in Southfields NY..right by Woodbury Commons. 2.37 there. i use 30 gal plastic drums because they are easier to move about. my drums have two 3 inch openings on the tops of them. i use a 100% plastic hand pump because i dont want anything electric or metal that could potentially generate a spark or static around my fuel but thats just me.

 

Good call on the pump being plastic. I was reading yesterday one one site about matching up the metal of the pump or drum wrench to the material being stored. I might get two 30 gal drums too but I might not have room for 2 drums.

I called a place thats the closest one to me, even closer than power gas in east orange, they have it for $2.29 a gallon and he said it was cool if a brought a drum to fill.

 

2.29 is the lowest i have seen, might i ask the name and location of this station

 

With a plastic fuel drum you would absorb water espically with e85

 

touch down for ignorance...keep your erroneous ideas to yourself. Alcohol comes in many forms and almost always is sold or stored in a plastic containers. as long as there is an air tight seal how do you figure its going to absorb water...magic?

 

What moma dont know dont hurt....
It's easy switchin maps,,, I drain my 91 from the fuel return line drain as much 91 I can.. till car dies....

 

excellent question. i will find out and let you know.

 

How do you figure water gets into brake fluid in a plastic bottle when it sits in a cold, damp, concrete basement

Magic I suppose...

Alcohol and brake fluid are hydroscopic, and for other reasons plastic is to pourous of a material to store gasoline or race gas in.

 

To answer the question, it will take less than 5 minutes with the fuel pump method.

 

Question now is pumps...Would I be ok getting a $30 plastic siphon pump like this bad rider?

i thought you needed 'larger' injectors for e85

 

Go for a goat throat pump. Ive used them for years with oxidizers/corrosives and flammables and have never had an issue.
