Engine/Transmission (1998.5 - 2002) Coolant In Isspro Isolator????

[ACarola]

Do you need to bleed the isolator out with coolant???? Will it mix with the fuel and go back down to the pump?? I seen a thread that someone thought it might have made there vp44 go bad . getting ready to hook my fuel gauge up. Any help would be great. andy or any helpful tid bits

There is a rubber diaphram in the isolator that seperates the fuel and antifreeze. Fuel on the bottom, antifreeze on top. When you get your fuel line hooked up, bleed the air out through the bleed screw on the bottom side of the isolator. Then fill the top side of the isolator and the tubing to the gauge with antifreeze.

Mine has worked great for 2 years. Haven't heard of failure of the diaphram that caused a problem. Hope this helps. Randy
