hi lads just out of interest what fuel pipe grade/spec should i use?
SAE J30 R9 classed as fuel injection pipe? or SAE J30 R6 classed as normal carb fuel pipe?
reason i ask i'm planning on doing a yb conversion so plan on running new fuel lines. when looking at the pressure put out by a new bosch 044 pump it says 5bar/72.5psi going by burton power site, looking on ebay and the net shows SAE J30 R6 pipe that can handle working pressure of 8bar/116psi other suppliers same grade but working pressures of 20bar/300psi then SAE J30 R9 with working pressure of 15bar/217psi the only real difference from what i can tell is the burst pressures SAE J30 R9 being a lot higher.
any brand or suppliers people can recommend?
thought about using 8mm microbore pvc coated copper pipe for the long runs from tank to engine bay any reason why this would be a bad idea?
