Hello lamby. The effects of using bio diesel vary with the percentage that you use...........the very first problem presented is that bio cleans the build up from diesel fuel out of the tank and fuel system......so either pull the tank a clean it out or plan on replacing several fuel filters..........If you used the gasoline fuel tank, I doubt that you will have much of a problem with this, but this is what I would do..........install a new main fuel filter and install a clear inline filter such as a Fram G2 or G3 before the main filter........keep a couple in the truck for the first 1000 miles..........I would not wait until the clear filter is plugged before changing...........for the first few hundred miles keep the tank full as possible and change the filter every 100 miles (the first filter may not last 100 miles)......replace all clamps with screw clamps (new hoses are a good thing to)


Every where on the net you will read that there is not any changes to the engine required to run bio.........this is not exactly correct..............

I Highly recommend to clean and set the pop off pressure on the injectors before hand............as well as set the timing.......

The viscosity of bio (depending on percentage and Your ambient temperatures) is heavier.......so, I recommend a electric fuel pump installed at the tank (3-5 PSI).........this eliminates several problems associated with bio........

You need to make sure your glow plug system is working as it should.............

Load test your battery and do a starter draw test..............

Make sure the top radiator hose reaches a temp of 195?F...

The above things will eliminate 99% of the horror stories.........

enjoy the ride,
