89 Dodge B100 bio diesel ?

[spooledup]

What needs to be changed to run B100 in an 89 ram ? Looking for info on pump o-rings , lift pump , fuel line , etc . Thanks

Fuel lines and some of the Orings might be affected. also the diaphram in the older lift pump. I have an 05 and have been ok running B100 for two years now. I'd run the rig on it and just keep an eye on everything, 89... your fuel lines and life pump are close to being replaced just from time... ...

If the IP has never been touched or updated it will need seals also.



Your fuel tank could be problematic as the bio will clean it out. After this many years there could be a LOT to clean out.



Given the age, I would replace all the fuel lines also. They have a tendency to rot internally and you never see it till the truck quits.
