What size of fuel filter will i need? there are about 3 different sizes and im not sure which one i will need for an 85 SE

 

If your SE is still injected there is only 1 replacement fuel filter for it.

 

its basically stock. i havent changed anything fuel system wise or anything like that.
when i searched autozone they gave me a bunch of aftermarket options for it.

 

what about fuel line size? i can just make one of the custom ones work. i looked through my manual but there isnt any info like that in there

 

they are looking it up wrong. there is one part number from mazda. different vendors are tricky, the oem and best one is the gold nippon denso. the black chinese made ones do not last as long, and the us made ones rust out internally and clog themselves!

 

why change the fuel lines??? stick with the oem lines. order a new filter from napa. from my experience, their filters seem to work well and be readily available. its what i'm currently using on my 13B powered GS in the way of a fuel filter.
