pondering WVO Tank options

[dfnder]

I have been considering a couple of WVO onboard tank options. As I really don't want to mess with moving my spare I am leaning towards...

1) installing a tank opposite the rear tank and rerouting the exhaust. My muffler rattles and I think it has degraded inside and I want to upgrade to a 2.25" or 2.5" exhaust anyway

2) putting a tank inside, adjacent to the hump. Although the inside tank could be a little messy I notice the hump does get quite warm driving and I think it would definitely warm up the oil in the tank.

I was wondering if it is really necessary to heat the WVO prior to the inline heating unit. If I use a stock automotive fuel tank without internal heat would I need to increase the size of the fuel supply hose to compensate for wvo?

Also could anyone tell me if the coolant line to the rear heater is constantly circulated? Rerouting to supply heat from here is probably easiest I figured.

I'll keep you all updated

1/ Fexlboi is considering the additional tank, in the same area, also.

2/ A tank installed in the back won't be messy at all if you installed the filler cap and venting to the exterior. Also if you used a remote filling hose like Delicat's you could fill outside the van and save the body panels from the assault of hole drills.

Personally feel that in west coast climates heating of an external WVO tank is unnecessary, but recommend an inline 12v assist pump on the WVO supply. Standard fuel lines will be fine with 11-13 liters per 100km demand. Read up on volumetric heat capacity, viscosity and specific heat properties of vegetable oils (boring stuff that I try and forget from school daze) to get an idea about the heating requirements of WVO. We've used external WVO tanks down to -16c, and an extend couple hour drive through Kamloops onto Chase with temperatures around -12c with no issues. That was without a WVO assist pump, though we might not have been doing our IP any favors by working it hard like that. The viscosity, lubricating aspect, and flow characteristic of WVO all operate, functional slow (Edit, flow not slow; though in the BC interior in December we drive slow), great at normal temperatures, the heating is a most for the engine only. Even in 40c heat we only mixed 25%, or less, WVO into our B5 diesel, used in our yet unconverted truck.

A newly installed CCAuto water pump and a sharp rock on a water bar showed me that the rear coollant lines circulate quiet well.

Cool thanks, Cheers!

i recently decided the the best option for wvo tanks is to use the stock tanks as is, but only removing the screen from the pickup inside the tank. and add a small diesel tank somewhere. i wish i had done just that instead of modifying the tanks on two delica installs so far...
