7.3 idi on bio
 

i have a 92 f250 with a 7.3 idi i was wondering if i need to change any o rings or lines to run bio diesel i know that bio eats away at some rubber

yes, you need to change your o rings and you return lines, international didnt switch over to synthetic rubber until 94 i believe.

ok thanks i wanted to make sure befor i started running it its starting to get warm so we can start cooking
