Album:Vegetable Oil Conversion:Installing the tanks
|
|
The next step is to actually install the tanks and dirty/clean filter/pump
and connect the hoses.
Pushlock connectors are excellent for avoiding leaks, but they're tough
to get on. Installation tip: Use silicone spray liberally on the
connector and inside of the hose before pushing hose on. It helps
immensely.

Starting to plumb the clean tank.

Starting to plumb the dirty tank
and exchanger/filter/pump #1
|
The bracket to hold
in the dirty tank.
|
I make a mount
to hold the dirty exchanger/filter/pump (as well as help lock in the tank)

The exchanger/filter/pump combo,
plumbed and mounted.
|
I add a second
strap for better strength.
|
I cut the cargo bay walls
where I'll be running the SVO hoses. I found some rubber molding that fits the edges perfectly to protect the hoses.

The back hole/port in the back bay,
molding being added.

The location of the back port.

My dirty collection pump,
as inspected by my cat. I buy an air powered pump. These things can pump about as much oil as you can supply them with air. The bus has an air compressor that does a whopping 15.5 cfm at idle. That means I can probably pull 15-20gpm at fast idle, maybe more.
|
Oops. The dirty filter as mounted
is in the way of the dirty oil pump.
|
The dirty filter
and pump, remounted so the dirty oil pump outlet can fit between.

The cargo bay, complete
(except for the collection pump).
|
Unfortunately the coolant flow
wasn't balanced. All the flow went to the heat exchanger and the coils were cold. So I tried running a bigger hose along the main flow to the first coil.
|
You can see the hack job
where the new hose comes in, bottom right. Unfortunately this wasn't good enough.
|
New setup.
Hot coolant splits, some goes to clean tank, other goes through valve to dirty tank filters and heat. This way I can turn off the dirty tank and still run WVO if the engine is having trouble staying hot.

The new coolant return tree.
|
The top of the heat exchanger
now has a valve on it to adjust flow - too much was going through the big exchanger and too little through the dirty coils.
|
The final setup.
