Can anyone give me a quick answer, I'm trying to order all the parts for a fuel system and I want some mount bracket for the fuel filters, I was going to use the oem fuel filters but I can't find any dimensions for them, so can anyone tell me what the diameter is of an oem/oem equivalent fuel filter? I'm prity sure s13 s14 r32 z32 are all the same so if any one has one of these they can measure for me it would be greatly appreciated.
