difference between 1st and 2nd gen fuel filter heads?
 

Can anyone describe, or better yet, show me a picture, explaining the difference between the 1st gen and 2nd gen fuel filter heads? I'm trying to figure out which one I have. Oh, yeah, and btw, I just bought an 06 Sport CRD!

The fuel heater plug is bigger,The 1st gen's had a problem where they would suck air threw the plug...also a fire hazard because the plug could melt mine did was $150 for a 2nd gen with a new mopar filter

wow i never had mine melt. but i had air in the fuel right after i bought it 4 years ago so the dealership bought me a new one. along with new cac hoses and the air intake hose because they had holes in them lol
