Try blending with RUG instead of throwing another mechanical gizmo on the car.

No thanks...

I'll continue with my GreaseCar WVO setup. I'm really not very interested in putting gasoline in my diesel engine.

If you have experience with a WVO boost pump, I would appreciate a brand/model recommendation - something that has turned out to work effectively and consistently.

Thanks!

I haven't heard of any of the electric pumps that actually work well for WVO. Most last a few thousand miles, tops. I have however heard of people having sucess using an oil pump to get the WVO moving. I believe they are called oil sump pumps, and you put the pump in the tank, somehow fit a rod to the pump that extends out the top of the tank, and then attach a 12v motor to that.

Another thing you can try is using larger diameter fuel lines. Your stock pump should be able to pull the fuel, unless it is really thick or really dirty. Maybe your lift pump is worn out? And I think most WVO filters need to be under suction, if you pressurize one side of the filter, you will not get very good water seperation.

I had problems with this too. I don't think it's an IP suction problem. It's dirty injectors.

When I first installed the kit the engine had no power under load when on VO. I put a 100 gallon treatment of Power Service Diesel clean in the diesel tank, drove it 10 miles down the road, and voila...grease ran fine. After several months I started having problems again, and this time I installed a clear filter just before the IP. This time it appeared to be VO starvation as I could watch the filter empty at high rpms. Blew compressed air through the lines and starvation problem went away. However was just having problems the other day, still no starvation at the clear filter, so I Power Service'd again, and now seems to be ok again.

One thing I am clear on now, is a WVO system is not low maintenance. You need to clean the tank from time to time, maybe blow air through the lines, and definitely run products through your injectors to clean any garbage out.

If everything is hooked up right, it should be low maintenance. The only problem I've ever had is air in the lines, and it sounds to me like you may be confusing air in the lines for diry injectors. If you put that much dieselkleen in the tank it will thin the oil out and there is much less restriction, thereby less chance for air to arise. On my old car, once I had everything sealed up properly I never had any problems. Drove it for more than 20k miles with no clogged injectors or a coked up engine. If you don't have clear fuel lines, you won't know if there is air in them. A clear filter won't tell you much.

Go to www.**************.com and check out the below item: It is a little pricy but it should more than meet your needs.

Yeah that one looks pretty good - anyone used it?

OTHER APPLICATIONS: This pump also works great when running Biodiesel or SVO / WVO. It can really help get that thick fuel moving to the engine compartment. If you plan to run a lot of biodiesel then we recommend you install biodiesel grade hose (not included in this kit). We can provide that for a nominal additional cost. Email us for specifics

I tell ya, I just looped the return on my frybrid system. Wow. Back to under 10 sec 0-60mph times. I blipped the throttle down at 65mph, 5-10 sec later it was screaming past 90 on veg, 3/4 throttle. Much improved over non-looped. So, adding a pump will prob do same thing.
