I have also heard that for these older model trucks you must also rebuild the IP and the injectors with new o-rings and gaskets. is this really true?? has anyone tried running biodiesel and it actually wear down the o-rings and gaskets. if this is all true where does one go in order to get the IP and injectors rebuilt or can someone with limited mechanic skills do something of this nature. thanks in advance to all who reply. i greatly appreciate these forums. i couldnt make it with you guys.
Never heard of having to rebuild the IP or injectors! Just change the rubber fuel lines and go!
I've been using B-100 for almost 3 years and haven't had any problems yet. I even use it in a 1952 HD-6 dozer with no problems.
I use clear poly hose from Ace Hardware, with a cheep clear filter before my main filter, so I can see any crud before it gets to the main filter.
