Changing To E85

[Adz2332]

Hey all

My injectors and fuel pump is on its way to change to e85.

How do people go about this?

Will i have to fully drain the fuel tank? Easiest way of doing it?

Any form of cleaning needed? Clearing fuel lines etc?

Will then install the pump and injectors, fill up with e85 then trailer to the tuner?

Thanks

Plus need to change oil, looking at a 20/50 weight?

Easy way to drain the fuel tank is to simply run the fuel hose into a bucket and turn the ignition on and wait til it stops coming out, shouldn't need to clean anything. Edited September 17, 2013 by AngryRB

obviously you can't change your fuel maps until you get to the tuner. Drive over on regular old 98 with a bunch of e85 in fuel drums and drain your tank there.

as for the injectors probably get the tuner to install them seeing as the car probably wont run at all on huge injectors

Just wasnt sure how umm padantic i should be with chaning fuels etc

I recently did a similar thing as my car is being retuned on E85 in the next couple of weeks.

I replaced the fuel hose around the fuel rail / fuel filter with some Gates Barricade stuff from Repco which is apparently bio-fuel friendly. Installed the injectors at home. The hard lines I left as they were.

Also pulled the fuel tank out of the car when I changed the pump over (don't forget to upgrade the wiring if you haven't already) to make sure that it was clean inside (couldn't really see that well in the garage with a torch) but as it turned out it looked like new. I've read elsewhere that if your tank is dirty you can throw in some E85 along with a few marbles or ball bearings and swirl it around. I also replaced the hose inside the fuel tank with the Gates submersible stuff to be safe.

I'll fill the tank with E85 and get the car picked up by a tow truck. Easy!

If the pump has a direct rewire then this will work

^^ if the car is stock pump/wiring then this wont work , ignition on- fuel pump primes for a few seconds then switches itself off

Can you just disconnect the cas and then turn on to pump fuel out or is that not good?

This. So easy. Put said fuel into daily.

Or, drive car to tuner, do the above and change injectors there.

Done.

as mentioned before stock or correct wiring won't let that happen. The pump only primes for a few seconds then turns off as a safety feature. A hard wired pump that's always on with ignition isn't safe in the event of a crash.

Even if you start the car?

Ahhh, pull of the return line! Now I get it! spazzed out a bit

Lol. I wasn't very clear.

Pull return line off post regulator, put a long hose aiming into a bucket. Start car and wait for it to stall.

Job done.

Crack open a beer.

cant you just get a piece of wire run it to the battery and the fuel pump fuse to force it to turn on?

[r32-25t]

You still need a hose to run to a bucket, so return hose is less f**king around

[ARTZ]

alot of crazy ideas for draining the tank here so heres mine,,

run hose from fuel filter to drum

If you have your pump wired for full voltage like most do, direct to battery...

I just stick a screwdriver and short the 2 pins on the fuel pump relay....hold it there till tank is empty....don't even need ignition on or a key in it for that matter....actually thinking I should just install a switch there even...to make fuel swaps easy
