Lexus IS300 Turbo Build Part 15/ E85 fuel pump upgrade/Return System Modification 

Awesome stuff. You should list the parts you used and links to them in your info section. Awesome build.

exactly what I was looking for, thanks a bunch man

Good walk through from start to finish. Props!!!👍

I’m in the process of doing this to my is. This has been really helpful!!

Great vid 👍 was intimidated at first. But I feel I can tackle it now that I know what I'm doing

I managed to keep the factory fuel rail in my IS300 by using an Aristo pump (unmodified) as a lift pump to a Radium FST-R that is mounted in my trunk. Since the FST-R bleeds excess pressure directly back into the can, all I had to do was attach the feed from the can in the trunk to the factory feed. Kept the factory dead head setup and used a Radium Fuel Pulse Dampener to replace the factory one.

Thanks for the video man! I’m in a tough spot, because my 2jzgte swapped IS is already set up for 600 HP, but the fuel pump is the only thing keeping me from reaching it. Car is tuned on E85 at 430 WHP, but I really don’t want a complicated dual pump setup. This Aeromotive 340 isn’t big enough to support 500+ WHP on E85 at anything less than 90% duty cycle.

I just realized the hose that siphons gas from the other side of the tank to the pump-side of the tank is made of rubber. Over time wouldnt it be eaten away by the E85? Did you keep this stock hose?

Where did you get the PTFE hose from?

I would like to perform thos upgrade on my aristo because she is struggling to get enough fuel. You didn't mention about these few holes drilled on top this little plastic piece with 3 outlets. My looks a bit different, should I drill it as well? Just to give fuel more bypass?

Hey nice video I have one concern though, does it starts easily?

Why did you clamp and close off the pump hangars regulator?

Where did u grt the bulk fitting

Hey man did your paper filter give you any problems ?

Whare did u purchase the hose?

damn potatoes! xD
