I have Red's double pumper in-tank setup with Red's (shimmed I think) modded 340's I think. Do I need to change out the fuel pumps to be E-85 compatible or will those pumps be ok?

SignUp Now!The following may not be of much help but I am speaking from my own first hand experience. I had the same concern as you when I bought my car 8 years ago. It already had a Red's double pumper setup since 2006 and I knew when I got the car I was going to run e85. Fast forward to today (8 years later) I'm still running the same double pumper setup on e85, perhaps not the smartest decision. Granted I did replace one pump 2 years ago because it's flow rate was diminishing (the pump never actually died) but you have to consider the pump was already 15 years old at that point. Most will recommend new pumps and replace them regularly especially if running e85 because risking blowing your shit up over an old pump you should have changed long time ago, is not worth it, and I would not disagree with that logic. But as with anything else, opinions will vary and my experience is just that - my experience.I have Red's double pumper in-tank setup with Red's (shimmed I think) modded 340's I think.

They're not GSS340 pumps.I have Red's double pumper in-tank setup with Red's (shimmed I think) modded 340's I think. Do I need to change out the fuel pumps to be E-85 compatible or will those pumps be ok?
They are in my car for more than 15 years and I use a paper filter that I haven't changed in 8 years.The pumps are not e85 compatible
Period
When Red was alive he told me they weren't e85 compatible and not to run that fuel on his pumps.Twice since I've had these pumps and have been running e85 my car set for 3 years with less than 5 gallons of e85 in the tank. Not so much as a speck of cornstarch anywhere in my fuel system, but I have heard some stories and some of them came directly from Red.
I was speaking to one of the turbo Buick members via personal messaging and he pretty much had the same exact experience as me or his car sat for 3 years it was 75% ethanol when he put it away and when he got it back out and put his engine back in it was 90% just like in my case and he's never had any kind of issues with any kind of corrosion or crap of any kind and he lives in Hawaii so he's surrounded by saltwater so that's not the issue. No one has ever seemed to figure out exactly why some of these things get ruined so horribly and others just don't have any trouble at all and I wish I knew the answer.When Red was alive he told me they weren't e85 compatible and not to run that fuel on his pumps.
I have seen some inconsistent results with intank pumps and ethanol fuels.
Very few can say they have had any longevity like what you have experienced my friend
I have seen several in intank pumps (some that claim they are e85 compatible)go away and do some heavy damage with very little indication the fuel pump was losing volume.
Some intake pumps have done well up here too.
The bottom line is it's a big ask and trust.
I'm glad it works for you (I went through 3 of his pumps in 8 years personally and several others)but it's a huge concern on my end when I'm dealing with guys cars and my own that I need to be certain the fuel is going to show up.
We do alot of injector cleanings up here and it's very interesting to see pump and fuel line material clog them up and then someone having 0 issues with the e85 fuel.
My car had no injector loss and no debris in the injector or filter when we tested it.
But I'm on ptfe lines and an aeromotive brushless spur pump.
Back when I was On 93 with 10% ethanol I went through several intake pumps and would have had to change it already.
My friends car has quantum intank pumps on e85 but he did ptfe lines and has 0 issue like yourself going on like 7 years and the car is driven hard.
He watches the computer hard though looking out for potential failures
Yup, that would be me and I can corroborate that story. Also, while my engine was out I even sent my injectors to Chuck for cleaning and he confirmed the baskets where still clean. The same injectors were on the car for many years, on e85, before sending them to Chuck.I was speaking to one of the turbo Buick members via personal messaging and he pretty much had the same exact experience as me or his car sat for 3 years it was 75% ethanol when he put it away and when he got it back out and put his engine back in it was 90% just like in my case and he's never had any kind of issues with any kind of corrosion or crap of any kind and he lives in Hawaii so he's surrounded by saltwater so that's not the issue.

Yes, I forgot about the injectors. I sent mine out as well for the same reason and they were perfectly fine.Yup, that would be me and I can corroborate that story.

After 15 years of playing with ethanol, this year I have decided to switch to alky. I would still be running e85 if it were not for the rising costs in my location.
Yes there seems to be no answer just alot of theories.I was speaking to one of the turbo Buick members via personal messaging and he pretty much had the same exact experience as me or his car sat for 3 years it was 75% ethanol when he put it away and when he got it back out and put his engine back in it was 90% just like in my case and he's never had any kind of issues with any kind of corrosion or crap of any kind and he lives in Hawaii so he's surrounded by saltwater so that's not the issue.

Over all the years that we've been running 10% ethanol in our gasoline I have never had an issue with my lawn mower and last year my brother had to put a carburetor on two of his Small engine devices because they were all crapped up with white whatever it is and I have friends who only run rec fuel, but again I've never had a problem.Yes there seems to be no answer just alot of theories.
One of which is expose to air.
But I have seen the fuel pumps and lines break down even on just 93 with 10%.
The guys racing up here hard core will use x85 when they want to really get after the tuneup just make sure its on the higher end.
To take the gas pumps and tanks out of the equation.
My theory is it's the way the stuff gets exposed at the actual pump.
e85 attracts water
Blends are def different here.Over all the years that we've been running 10% ethanol in our gasoline I have never had an issue with my lawn mower and last year my brother had to put a carburetor on two of his Small engine devices because they were all crapped up with white whatever it is and I have friends who only run rec fuel, but again I've never had a problem.
Also, the rubber portions of my feed and return lines on my car our original and so is about a 1 ft piece of rubber hose that I installed on my feed line back by the tank over 30 years ago.
As far as aftermarket e85 goes, I bought 15 gallons of Sunoco e85 because I stumbled on a place near me that had it for $5.75 a gallon. If you buy a 5 gallon jug of the stuff from Sunoco it's about $13 a gallon I would never pay that but I forgot to stock up on pump e85 before they switch to the winter blends so I was glad I found that and I swear my car runs better with it and by better I mean it seems like it makes a little more power and it doesn't smell like rum which I have never liked and I swear you can smell a hint of 104 octane unleaded fuel that I figure is probably in that stuff. Compared to pump e85 it has almost no smell.
There comes a point where preventative maintenance costs alot less then the failuresWell, I finally found something in my fuel system that doesn't like E85. After 8 years of use, I decided to change the replaceable paper filter element in my aftermarket fuel filter. The filter looked like the day I installed it, but the coiled wire inside the filter to keep it from collapsing is made out of aluminum. I tapped the filter on my work bench to see if any thing would come out of it and something did. It was a piece of the coiled aluminum wire .I then tried to pull the rest of it out with a pick and it came out in three pieces. You could easily see the four very specific spots where the wire was attacked but the rest of the wire looked new. Since the wire was on the inside of my filter, there was nothin between it and my fuel pressure regulator. I can't help but imagine the problems that piece of wire might have caused if it had broken loose and traveled up my fuel line. Even worse, I wonder what a nightmare diagnosing a possible fuel delivery problem might have been. Lesson learned. I will now be replacing my fuel filter every seven year whether it needs it or not.
