Im been searching for a little bit now and can't find much info on the fuel lines in each car, I'm swapping all the parts from my S5 to a S4 including the fuel tank since the shell didn't have one, Are the lines different sizes on the S4 then the S5? I believe the tank is a little larger on the S5 but it seems to be close enough to fit.

Thanks in advance for any info.

 

Pick the least rusty lines, tank will fit if you use the same series straps. Adjust depth or Use the fuel pump from same series tank

 

are the s5 lines bigger though? the ones that run from the tank to the front of the car?

 

Mazda shows the same part number, S4 and S5. the vert and coupe are different, but it is probably something minor

 

Cool thank you for your help, I'll try again this weekend to get it in there
