Looped return ?

Postby Ace » Tue Jun 30, 2015 2:14 pm

Hi all...
Anders from Norway calling ;)

Just wondering, maybe a newbie question, but, on the WVO schematic by Sunwizard the looped return is on the VO tank line. But when you are purging with diesel that line will be closed won`t it ?
Or do you put the loop between the tank valve and the lift pump ?

Hi, look at the diagram again, the WVO supply line is not closed, its open from where the return enters near the valve back to the tank. This design is so that the WVO in all the lines gets quickly pushed back the supply line to the WVO tank by the new diesel entering. This makes for much faster purges than any other design.

Aha.. Thank you Mr. Wizard
I`m innstalling this on a JCB Fastrac, and it has the same 12v P7100 engine as the Ram.
It will be 1m lines from the tank to the engine, and be used mostly at summer. Do i need HoseInHose or can I just wrap the VO line next to the heater lines with insulation ?
