Hi japar,, BE CAREFULL,, my side business is diesel repair, hot-rodding diesels, Custom automatic towing/hotrod transmissions. All on Dodge pickups..
IF you have a '98 and earlier Dodge Cummins pickup with the P7100 mechanical injection pump,, you probably will have zero problems.. IF you have a '98.5 through '02 truck,, put $2000 in the bank,, you will need it for purchasing a new injection pump.. unless you keep the waste oil percentage down below 10% or so.. If you have a '03 and later, set aside about $2400 for new injectors.. the pump will probably survive, but the electricly opperated injectors don't like any 'odd' fuels..
If you have a Ford or Chevy,, the later trucks are Common Rail injection systems.. keep the waste oil percentages low.. personally I'd not go above 20%.. the amount of savings is too small to off set buying and replacing even ONE injector... it's a small war to swap injectors... and if an injector is leaking, or sticking open,, it can melt down a piston.. then we are talking some serious cash...
I have an all- mechanical injection '97 truck,, I'm thinking of putting it on the road and burn about 30-50% waste and ATF, But buying an injection pump, or injector, even only one injector negates all the savings...
Best of luck..
multiple filters are required,, injection systems cannot tollerate any dirt or grit.. or again,, you will be buying injecion pumps. $$$
Make sure you figure out a way to swap tanks with NO AIR in the lines... diesel injection pumps get real 'mad' when fed only air..They don't pump air very well at all,, and you will be on the side of the road..
Let us know how it works out..
