Hey guys,

I am almost finished with my second tank WVO install on my 82 300D.

In case any one is interested in doing this project, it is fairly time consuming. I have spent a good four days on my conversion so far. I have built, painted and carpeted a special platform in the trunk that raises the WVO tank to allow spare tire access, I have installed and secured the tank with straps, mounted the large Racor filter to the tank with a custom bracket, ran Greasel's 3B hose from the tank to the engine bay, plumbed up the solenoid and fuel bypass valve in the engine compartment, and wired up the solenoid and new glove box mounted fuel guage (and boost guage). I will post pics of my install when it is all up and running.

Here is my question:

I still need to connect the coolant lines heading to the WVO tank to coolant lines in the engine bay. Greasel provides two 5/8" Tees for splicing into coolant hoses. The trouble is, the only coolant hoses of that diameter are the hoses on the fire wall associated with the heater core. I see a solenoid by the battery and traced the hoses back to a second water pump. So I am assuming all the hoses in this area are only flowing when the heater is engaged? There is one hose coming right out of the block that heads to the firewall, is it safe to say this one is always flowing?

Where should I splice in? Should I get bigger fittings and splice right into the top and bottom radiator hoses?

Also, how do I identify a hose with positive pressure and hoses for returning coolant to the radiator.

I hope to get this project done today, so any input ASAP would be awesome!

Thanks guys, Cassidy
