You are correct all of the diesel or oil that is in the IP and shared fuel lines will be sent to the wrong tank upon switching. I made sure that all of the shared lines were as short as possible and I haven't had a problem. It will purge in about 1 block.


I chose to try the two six ports to maintain the stock design of the Lift pump pushing through the filters. It worked great for about 300 miles until my pollaks failed. I will be replacing them with a pair of greasecar solenoids that will be arriving tomorrow. The new set up will have the lift pump pulling through the spin on filters. I will update this thread when I put the new solenoids in.

As for the second tank...I'm not sure. I will take a look in the trunk tonight and get back to you.

Update:

I pulled the conversion kit and sold it about a year ago. The mess and time of preparing the oil, mess of spills in the trunk, and possible engine damage made me decide that biodiesel is the way to go for "green" fuel.

I used a funnel to fill my OEM tank with veg for a while, then figured out a better system. Walmart sells a 7 gallon container in the camping section called an Aquatainer. Its got a threaded cap on it that has a threaded hole in the center of it for a little plastic valve that comes with it. Toss out that valve and put a pipe to hose connector on it. Attach a 3 foot hose and you've got yourself a gravity fed fueling station. Put the hose in the tank. Tip the container on its side and lay it on the trunk.

If you have one of the greasecar fuel tanks. You can use the little valve that comes with aquatainer and lay the thing down its side on top of the tank. Open the valve over the fill opening of the tank.

square funnels rock.. no gluging

I wish I could do SVO.. well I could, but I would have to burn diesel on my way to work since its only 5 miles from my house.. Unless I can have a small heater in the veg tank at all times and power it by solar or something


give me ideas people...

The Don- you live in FL. one tank it!!

I find that the small gatorade/lifewater bottles will screw right into the OEM tank filler, cut off the bottom and your set. no hands

I am surprised that people still take single tank as a serious option...

I personaly believe running wvo destroys these engines over a long period of time, maybe 50k. Its probably extremely bad to start a cold (even if its 90 out) engine on wvo as it probably doesnt burn completely and gunk sticks around. Ive worked on a few wvo cars, all of which had the worse blowby ive ever seen and with less than 300k on them. Thursday morning I changed the oil on a veggie car (5k change intervals) and his delo 15-40 smelt like food and had a viscocity not far from water. The car has so much blow by he had to have an extra oil seperator installed in the engine bay (one which he has to empty monthly) becuase the normal one became overloaded

You are restricted from further posting on this thread.

Thats fine. His setup still looks very well done compared to many others posted around the internet.

Me too! I'm not a real fan of going to VO, but your system looked very well done and you used good quality parts! I use biodiesel exclusively and have no regrets. MB and Cummins did a study and found that using Biodiesel had the benefits of running 80% cleaner, reduced operating costs by up to 56% depending on conditions and resulted in about 50% longer engine life!
