Hey im trying to get the fuel lines off the fuel filter nipple and they are not budging. Upon closer inspection they dont look so good so i would rather replace them with High Pressure fuel lines. I dont want to cut them up and take em to the autoparts store just yet, so i would rather know there diamter. Then i can go and purchase them, and just cut the old ones off and put all new fuel lines with my new mazda oem filter.

Thanks

cut off the lines, remove fuel filter, bring fuel filter to auto-parts store (you say you have a NEW filter so take THAT,) have THEM fit the right size on there. Don't forget to buy clamps. Make your life simple, don't complicate things.

 

yeah i have clamps and all that. I just wanted to know the size before i go. i will be bringing my fuel filter to double check. Thanks

 

make sure you buy ENOUGH fuel lines and that you measure twice to get the right length!!! ( i speak from experience)

 

5/16"

 

Come on you weakling! Pry those lines off!
