Engine/Transmission (1994 - 1998) Fuel gauge tubing

[BLeinart]

Any suggestions on filling the fuel gauge tubing with antifreeze. I got a set of isspro gauges and am about to install. Pyro, boost, and fuel.

Surely someone knows an easy way to do this!

I'm not sure what you are trying to do; fill small tubing with antifreeze? How small? The only way I can think of would be to immerse it and slowly work the air bubbles up and out. Or use a syringe and inject the coolant from the bottom of the tube with the tube in a vertical position so the air goes up and out. Or use the syringe or other suction device to suck the coolant into the tube and the air out.

do not use antifreeze just bleed the line. if you have an isolator throw it in the trash. if you think you must use the isolator get a oil syringe from orileys and draw a vacuum on the gauge side next fill the syringe with atf and fill the gauge side you need to pressure down the diaphragm with the fluid. the reason for not using antifreeze is the isolator will fail and the water antifreeze will migrate back toward the pump. the isolator is a pp fix for a non existent problem. none of the equipment or trucks in the last 50 years had them.
