I decided to add a write up for this since I replaced my stock pump with the e85 fuel pump. Yes this its an overkill for a stock turbo setup, but since I already had the inline setup i figured i might as well re-use it. I Highly recommend doing the 255 Inline Setup over this If you want to run Full E85 with a healthy stock fuel pump. If your stock pump is tired or on its way out, then I recommend doing this replacemnt over the Stock pump to get the increased flow, plus this pump is only $107 shipped. If this install looks to complicated I recommend that you replace your stock pump and do the inline setup. Running Both the 255 inline and e85 walbro will OUT FLOW Any other pump setup out their that can run on the LPFP side. This setup could out flow more than The Visnu pump setup or be very close in flow compared to it. Without fuel flow testing i can't say for sure. Visnhu's setup uses the same E85 pump (just in a special billet casing) allowing you to run it inline with your stock pump. This would be a perfect upgrade to run full e85 with RB's. If the HPFP can handle it? That i can't say for sure.
Here is a link to the inline setup that I created.
Here is the pump and kit setup i bought for $107 shipped! (prices vary with the sellers)
For information on removing the pump refer to the link above. I also forgot to snap a picture of the stock bucket after i pulled it out, but once you get the pump removed you will notice that the black lid is glued to the bucket, as well as the 3 prong black piece that holds the pump. Just use a flat head screw driver to break it them free from the side of the bucket.
For pictures showing the stock bucket and how to remove it refer to this link
You can buy the alluminum tubing online, or at OSH (where i bought it). Just dont make sure its Alluminum. Steel will require a steel bender. I bought my Alluminum tubing bender at O'reilly Auto parts, but these are also on amazon.
I used 3/8's tubing with my setup
Here is a nice tubing bender
This was my first Design
This setup would work just fine if running just the pump, but with the inline it puts force on the tubing causing it to bend over time and could affect your fuel level sensor like it did with mine. Hense the reason i revised it.
This is the New Design.
I bought my seal all years ago, but you can buy it here or at your local autoparts store.
The outlet is connecting to the inline 255 setup that I installed, if your just running the walbro e85 pump you would connect the outlet of the T to the orange hose that was originally connected the top of the stock pump by a black bundy with a green tip.
I didn't show how to remove the pump or re-install the bucket since you can find that information in the DIY walbro 255 install. (link at the top of the thread).
If you got this far you must have completed the install. If your running both the inline and the e85 walbro setup i recommend that you replace your 20amp fuse with a 25amp. I did full 7k rpm pulles on the 20amp fuse without it blowing, but just to be cautious i increased it to 25amps. I ran full e85 with the just the inline setup, but my stock pump started acting up so i replaced it with this one since it was much cheaper than a stock replacement. With this setup you should be good for 800+ hp on 91 and 600+ on full e85 if your HPFP can keep up.
