Is anyone running an inline fuel filter with e85?

Also so I’m trying to figure out the best option for upgrading the factory lines.

-8an feed with stock feed as return or -10an feed and -8an return ?

 

Do you need to do upgrade lines to run E85?

 

Im running -6 off the stock hard line, which is the same size as a -6. The rubber hose with that banjo is the restriction. Everyone says run -8, not sure why though. I'm running -6 making 600hp and I think stewart is running -6 aswell making like 1000hp.

 

You will basically never need larger than a -06. I am making 1,000 on a single -06 and E90. For a filter, this is your best option on the market:

ID F750 Fuel Filter - Injector Dynamics

 

The only real reason you need lines (for most builds) is if you are changing the pump hanger since they aren't going to adapt to stock hard lines.

 

No

I have been making over 600whp on e85 on stock lines forever. Just got a walbro in take 450 pump and Id 1300cc injectors.
