New to forum. Saying howdy and asking questions. Just bought a 86 f250 w/6.9. The wire going to the heated fuel line was burned into. 1-How can you test to see if the heater is good ? 2- How does it affect performance with vs without. 3- Does it do enough to warrant replacement, and is it controlled or does it stay heated all the time. Thanks in advance for any advice. p.s. Live in SC. Not very cold.
