Re: what is neede for E85
I was told everything must be in stainless or drain e85 if not using stainless lines etc when sitting for long periods . I also want to run e85 in my build . Also injectors set up for e85

Re: what is neede for E85
I will be making the switch next year. You will need injections that can delivery the extra fuel needed to compensate for the low BTU value of E85. The fuel pump must be compatible with E85 as well as the tank and lines.
I'm going with 2 Bosch 044 external pumps. My teflon coated lines are fine, but I'll need to switch out my fuel cell sportsman bladder to a pro cell bladder. I'll possibly need larger injectors as well.

Re: what is neede for E85
I am running it, E85 is not as corrosive as most will lead you to believe. I have run it for awhile now, and drained the tank several times, let it sit over winter, etc. No problems.
I do have a weldon pump rated for E85, stock sumped tank, and 84# injectors.

Re: what is needed for E85
I've read that the octane is between 94-96. Is that really going to make much of a difference?
Also, if it does make that much difference and I want to start running it in my daily driver, do I have to make all the necassary changes? The fuel will never sit more than 2 days and will be run out nearly every week.....Thanks

Re: what is needed for E85
its not cheaper in a daily driver your MPG will fall I think the magic number is 75cents per gallon for it to be a better value for a DD

Re: what is needed for E85
Some good info contained here on it... there is also E-98 you can get... I would think you could run the two on the same injectors but it might require a different tune... E-85 for road operations and E-98 for racing...

Re: what is needed for E85
yeah the 105+ octane is a rumor BUT... this fuel has a synergistic advantage that prevails due to it's nature... charge air temps are LOW with any ethanol or methanol fuel and it's an oxygenated fuel to boot. So you can get away with running much more boost without feeling the effects of detonation nearly as bad. They also sell an upper engine lube that anyone running ethyl based fuels can use, helps to lubricate the upper engine as alky will dry EVERYTHING out!! Plus it's scented so it smells like strawberries, banana, etc when you start it up. It's called M-3 I think. Saves valve seals, injector seals etc...

Re: what is needed for E85
Never said wiki was the bible in fact most of the time I hardly trust what it says. but that one is pretty spot on. I just have my experience from running methanol in our race car and we have some very good friends that run Wyoming Ethanol that run it in all of their race cars. They've tried to get me to convert in my Ty but using methanol for all those years and what a pain in the ass it is on fuel systems kinda turned me off of it until I learned a little more about it.

Re: what is needed for E85
I don't know about the info on the wiki page, but around here E85 says 105 octane on the pump. I'd think that if they labeled it 105 and it wasn't that would be false advertising. Either way, I plan to run a tune for it when I finally get my Ty back into shape.

Re: what is needed for E85
"There is no requirement to post octane on an E85 dispenser. If a retailer chooses to post octane, they should be aware that the often cited 105 octane is incorrect. This number was derived by using ethanol’s blending octane value in gasoline. This is not the proper way to calculate the octane of E85. Ethanol’s true octane value should be used to calculate E85’s octane value. This results in an octane range of 94-96 (R+M)/2. These calculations have been confirmed by actual octane engine tests." - Changes in Gasoline IV, sponsered by Renewable Fuels Foundation.

From http://www.change2e85.com/servlet/Page?template=Myths
1. E85 Ethanol is corrosive
Yes ethanol is corrosive, but not very much. Gasoline is corrosive too. Ethanol is biodegradable in water. So it has a tendency to contain and attract water. It is not the corrosive properties of ethanol that can cause damage to your vehicle; it is the water which can rust a vehicle’s fuel system from the inside out. Today’s vehicles (since mid 1980s) have fuel systems which are made to withstand corrosive motor fuels and rust from water. Also today’s distilling processes are superior to way back when. We now have better techniques for drying out ethanol or reducing the water content.
2. If I put E85 in my gas tank, it will eat it away.
If your car was built in the old days, it was had a lead coated, steel tank. The water in ethanol would cause the tank to rust from the inside out. The government mandated that all gas in the USA contain 10% ethanol to help reduce tail pipe emissions. In the 1980s, automakers made vehicles with fuel systems to be ethanol and rust tolerant. Gas tanks began to contain polymers and Teflon which are extremely durable.
6. E85 will eat my rubber fuel lines.
This is another myth from the old days. Rubber technology has significantly advanced so the concerns of a 20 year old car or newer having issues like this are extremely rare. Plus the 15% gas will help keep lines lubricated.
7. E85 will destroy my fuel pump.
E85 won’t destroy your fuel pump. If you convert a high mileage vehicle to Flex Fuel, the E85 will cause the sediment in the gas tank to dissolve and then get sucked up by the fuel pump. It is believed that this sediment may shorten the life of the pump of your higher mileage vehicle (100,000+). We have had no reports from customers with damaged fuel pumps.
From http://www.ethanol.org/index.php?id=50
E85 is the highest performance fuel you can purchase at the retail level with its octane rating of at least 105. Because E85 vehicles are flexible by nature, owning an FFV is a practical way to enter the world of alternative fuels without any limitations on the vehicle's range.

Re: what is needed for E85
it depend what you whant to do if your truck is built e85 is the way to go. you need bigger injectors biggger fuel pump bigger lines in and out .the good thing about it you can boost more pound. make more horsepower with e85 it depend on your set up your tune .

Re: what is needed for E85
Attempting to equate an octane value to E85 is a bit like saying "All premium gasoline is 93 octane".
The reality is, blends vary from different region to different region, and during different times of the year, just as gasoline does.
Believing the number on the sticker on the pump, whether it's an alcohol based fuel or gas, will eventually get you into trouble. There could be as much as a 10 octane number swing at any given pump.
As far as the original question goes...
If you're concerned about it, you can find a late S-truck plastic gas tank. You can replace the lines with braided, and get an alcohol compliant fuel pressure regulator and fuel rails.
The reality is, many people run on stock GM fuel system components with no ill effects. These are primarily not Daily Driver class vehicles, though.
You will need larger injectors (unless you're already running 2x the size injector that you need) , and a really well worked out tune to make it driveable.
