| HDJ81 Fuel Return Line?
Hey all,
Is there a fuel return line back to the HDJ81 or HDJ80's fuel tank or is the fuel just looped back to the IP?
Thanks
Karter

There were 3 spots that we had to weave through rubbing on the gutters, and just clearing the fender flares, I'm happy we found a spot that we could clear out by hand, to get turned around. I think everyone suffered some type of body damage."

| Don't all modern FI systems have return lines anyways (to the tank)? I know Diesels have always had them but I thought most gasoline EFI vehicles do too?

| Different applications for different diesels, some use it for cooling, some for removing air bubbles from the fuel, some to keep pressure on the injectors. Some all of the above | |

And as they pump up to 46 litres per hour ,you would have the problem of what to do with all the excess fuel.

| i was just trying to figure out for my future wvo conversion.
I know in the case of my dads BJ70 i can just use one hydraforce valve for the conversion. While in the case of the 81 i would have to use two hydraforce valves.
Thanks for the info! | |
