e85 upgrade,maybe,maybe not?

That is not 36%, your are logging the lowercase PID not the DMR so the value is halved, so that is 72% actually, but that still is very good, you look to have enough room for the the alcohol test.

That makes sense, I knew it couldn't be that low, but I'll take 72! Thanx for the help lito!

This morning and keeps on falling. I'd say I made the right choice last year!

I paid $2.54 a gallon yesterday.

It's still over $4 a gallon here. One station has a monopoly and he takes advantage of it.

I feel you. Only Rebel carries e85 here in Vegas, and they charge 87 octane price for it. So $3.39/gal currently. Worse is the quality. Pulled a ~50% ethanol result from my tester off one station, had to drive to the next to get 80%. Ethanol has not been a friend to me lately :/

I'm getting closer to pulling the trigger. here is what I'm thinking.....

I currently have a hose taking the place of the stock rubber fuel line that connects the stock metal fuel line to the fuel rails. I do not know if this hose is E85 compatible, I also have a short piece of this hose jumping over to the other fuel rail.

I'm thinking the EFI push on fitting that is currently used on the metal fuel line can be moved to the fuel pump?

Then run new #8? e85 compatible , filter from the tank to the fuel rails?

would there be any benefit to using a "y" block instead of jumping from rail to rail?

Running the rails in parallel, which I think is what you're saying here, is superior to running them in series. The reason is that if there is a pressure drop it's more uniform rather than affecting one side more than the other. That's less of an issue with a return system, but still.

yeah,i was thinking the temps would be more consistent as well.

stock filter OK to run w/ e85?

Oh no... those are paper element filters. Paper will have a tendency to tap water which e85 will naturally absorb. You need a stainless element filter. Fore innovations ftw

I ran the stock filter for about a year without issue but I changed it every 2-3 months just to be safe. They are very cheap and easy to change but they are also a restriction when you are trying to flow alot of fuel like E85. Best bet is to upgrade the lines from your fuel hat to the fuel rail and drop in the Fore filter like Crown mentioned. That's what I did along with removing the PPRV check valve on the fuel hat and I dropped my fpdc a good 25%.

 

[one eyed willy]

any issues from taking out the check valve? i heard it makes the car harder to start?

 

[JeremyH]

I removed mine. Only difference is you cant jump in the car and go key in straight to cranking. You have to key on wait 1-2 seconds for the line to fill then crank. This is on first cold start. If you driving around running errands and your getting in the car I usually have no problem going straight to cranking.

The pprv valve and stock fuel line to rail connection are the smallest points/most restrictive part in the stock system.

I would do the line and filter upgrade first the ss filter element is nice and you just clean it and reuse it. Also tearing into stock or gt500 hat isn't the most pleasant way to spend a weekend lol

When it does not start or stumbles it can be embarrassing... especially if you show the car. Just sayin. We put them back in for a couple customers.

I recommend a dremel, patience, and a lot of zip ties hahahaha

 

[BruceH]

The stock filter works just fine. They are designed with flex fuel in mind. I've always run the stock filter, lines, rails, etc and never had a problem. So have millions of flex fuel vehicle owners.

Oh I know, at this point I have probably built and modified 100+ fuel hats. While you learn all the tricks it doesn't make it any more pleasant. lol

While you haven't had an issue, doesn't mean there isn't room for improvement especially with e85. Dysan saw a huge improvement with the swap even at his relatively low hp level 550-600hp.

I had to run a different filter as I'm return now, but I love that I will never have to buy a filter again.

 

[dysan]

Yup...and right now in this weather my car was running 10.45's last night so I have to assume it's around 650rwhp and I'm only seeing .370-.380 fpdc so I still have a ton of fuel capacity.
