I switched over to SVO and the vehicle sputtered andcoughed and the engine cut out. What should I do?

Most likely, the fuel lines weren’t primed properly and there was air left in the system that caused the engine to turn off. Prime the fuel line by disconnecting the SVO fuel line to the switching valve and turning the accessory fuel pump on or using a hand vacuum pump until the fuel flows without any air bubbles. Reconnect the fuel line to the switching valve and tighten the hose clamp. Make sure that you are on the un-looped diesel system when you attempt to start the vehicle. If the vehicle is air-locked it might takes several attempts to start the vehicle again and to purge out the air from the system.

I’ve been running the car for 15-20 minutes and the vehicle is up to temperature, but the tank isn’t warm. What should I do?

Most likely, the coolant lines weren’t primed properly and there is air left in the system that isn’t allowing the coolant to flow properly. Prime the coolant line with a water pump or hand primer pump. You might have to cycle the coolant a couple of times to purge the air pockets completely. Make sure to check your coolant level, as well.

I switched over to SVO and am experiencing acceleration issues and lack of Power. What Should I do?

Most likely, there is restriction in the SVO system. ┬áThis is usually caused by a clogged veggie filter. Change the veggie filter. Don’t forget to prime it (fill it up with fuel) and make sure that it is sealed well.

I changed my SVO Fuel Filter and am still experiencing acceleration issues and lack of Power. What should I do?

If you are running a system that utilizes the stock fuel filter for both veggie and diesel, you might need to change the stock fuel filter.

I changed the SVO and Stock fuel filter and am still experiencing acceleration issues and lack of power. What should I do?

Most likely, there is some other source of restriction that will have to be traced down. Restriction can be caused by numerous foreign objects that get pulled up into the system. A Hand Vacuum Pump is a convenient tool to pinpoint the source of restriction.

I switched over to SVO and my vehicle began to sputter and cough and the engine cut out. What should I do?

Most likely, there is air that has been introduced to the system. If you just changed your fuel filter and didn’t prime it properly, that could be the source. If you primed the filter properly, check to make sure that there is nothing loose on the filter. If nothing on the system has been changed recently, then the air leak will have to be traced down. A hand vacuum pump is convenient to trace down air leaks. Check all hose clamps and fittings for a secure fit, as well.

Thank you Charles it is great to drive 206 miles a day round trip and not have to pay $4.06 a gallon for diesel fuel. The check engine light has not come back on after I turned the pressure down on the veggie pump to 12psi thanks again
