Thanks for all the great info....

It seems that I'm no worse off with B100 than ULSD and I'll be replacing all the O rings anyway......and should be checking them right now since my car already has 170K miles.

I'm off with the diagrams to have a good look at my engine and get more familiar with all the locations.

I feel better now.....I'm going forward with using B100 full time and feel more confident that I can handle the O ring replacements when necessary.....at least for the fuel and filter lines.

I'm still fuzzy on the IP though,...this is still a bit intimidating for me. Does it involve removal of the pump to replace the O rings.....??

Is there a play by play on this procedure in forum?
