Ben I saw this first photo on Plantdrive's website of a Vegtherm Mega installed in a Cummins. For a year and a half mine was mounted under the truck outside the frame rail. After the Vegtherm Mega the vegoil went through the gauge sender then the steel supply line to the fuel pump. Since the steel supply line is very long and NOT INSULATED I decided to copy the Cummins installation and relocate it over the fuel bowl. I used two mounting screw studs from the engine cover to secure the P clamps for the Vegtherm Mega. I gained almost 20*F and run at 170*F and hotter on warm days. The red thing is a 26 micron post filter after my vegoil temp gauge sender then the a mini ball valve and down to the fuel pump. Make sure you use J30R9 fuel injection hose. It's bioD compatible and can take hot fuel <300*F.
