This was discussed in another thread, I wanted to create a thread on this topic as we have a lack of info in this section.
A few members have shown me an awesome, cheap, and unusual method a member used to fuel proof the OEM fuel sender so it won't be corroded by e85 fuel. I'll get some more research done and post pics of my progress.
I'll make sure no one in the vicinity will be smoking :kneeslap:

Ok cool, thanks. If you can, compare it size wise to the OEM Si one. If it fits, ill run em. If not, I'll do oem and the putty.
I'm a little confused... we all run E85 here. What part corrodes exactly?
Because I just took out a fuel pump assembly to modify it and put a bigger pump in for a customer of mine who has been running E85 for two years and I saw nothing wrong with it?

The fuel sender itself corrodes, i'll try to find pics. Hold on

Here's Ainokea's post:
UPDATE 9/19/12 - The top of the sender has started to work. My entire fuel gauge is working now. It has been for the past 3 months or so. I think this may be a solution. Only more time will tell
sup...been a minute. any who...i recently converted to e85 and have great success.
things to know about e85 is that your injector duty cycle would increase from 20-30%, so you need more fuel pumps, injectors, ie.
also, with e85 it corrodes the board inside the tank and makes the gas gauge not work. no one has actually done a diy yourself because...idk why but also it seems to always fail.
hopefully this is the successfully solution for everyone.
i have currently been back to the station for more E85 six different times, and put almost 1000 miles within 20 days. lol i been driving a lot haha
the walbro 400 pump is amazing. it is slightly larger than the walbro pump but you need to modified the heck out of it...lol i done so much already. why stop there?
any way on to the pics ..not for the fate hearted haha
here is the stuff i used...was just trying stuff out.

so here is day 1 installed...now i f'ed up and cover the top...so my pump never shows full again. after about 3 bars are go my gauge comes back on.

and now on to the pump....here is the first thing you see when you try to put this bad boy in...

dremel goes a long way...you actually have to do more than just the pump, like a 1/4 more.
http://i25.photobucket.com/albums/c88/Andrea808/Tonys%20stuff/IMAG0281.jpg
this is pretty flush...but then the next problem was the cover. the pump had some things on it and...well...more dremel action haha
http://i25.photobucket.com/albums/c88/Andrea808/Tonys%20stuff/IMAG0284.jpg
so cut the bottom top flush too, also you can see where i notched out the cage for the return line here
http://i25.photobucket.com/albums/c88/Andrea808/Tonys%20stuff/IMAG0285.jpg
for the wiring you cant use the stock clip. just pop the clips out of the black harness and they fit right on. i also use the stock hose as a return, and cut the cage so it can go straight down. you can see that in this pic too
also note, that i have already previously cut the cage up around the top where the pump goes into, this was for the line on the feed line.

cool...and thanks. dont have to do what i did, but showing what has worked so far...keep yo fingers crossed! haha
thanks!
