Are my stock fuel lines ok for B20?

It is a 93 F350 7.3 with ATS turbo. I just want to burn B20 at the most and was hoping the stock lines would be fine.

You should be fine, it's not like they'll dissolve over night if they're not compatible. Just keep an eye on the fuel filters, they'll clog up due to the biodiesel cleaning out the tank and lines.

does anything else have to do done to the engine to run B20?what about B99?
Sorry for the thread jack(same motor btw)

I'm trying to change all my lines to handle biodiesel, and by reading on here, i've learned that Goodyear SAE 30R9 fuel injection hose from auto zone will handle bio fules. Chang the hose from your frame to your lift pump and all your injector return lines with the stuff. Also the o-rings should be replaced with Viton o-rings. They will hold up too.

I believe that Spencnaz was the first to help me, but it takes a while for biodiesel to eat through regular rubber. On b100 i think it takes close to a month before it starts swelling and breaking down.

Wow,even with the upgraded fuel lines its that fast?I guess Ill stick with b20 since I dont feel like doing my fuel lines every month.

With a '93 I would suspect that no rubber or plastic fuel system components are compatible with even B20. When we converted to bio-diesel (we eased into a B5, then B10, then B20, B50 to B70 blend), we noticed that a few of our suspect components, that we thought could be okay, began to deteriorate at B20.

just my $0.02 worth.

What i meant was with the factory lines i believe that it takes close to a month to start wearing down, with the proper rubber in the fuel system it should never be affected by bio-diesel.

Also, since Rickie has seen a problem with B20 eating things, i wouldn't trust that on the factory rubber. I just ran it one time to try and clean out my fuel system.
