    '08 or '07 Motor ID and Fuel Tank Vent Question

    So late last year I bought an '07 RXT which was upgraded with RXT-X parts from sellers friends damaged '08 RXT-X ski that was declared salvage by insurance company due to hull damage. The ski runs GREAT (I've had an RXP that I upgraded and this is way faster). The guy I bought it from did not speak english well but most everything from an RXT-X is in this ski. Handlebars, instruments, ECU, intercooler, x-charger, motor intake and cold air, entire VTS system, pump, impeller, even the gas tank. I am doing lots of upgrades and have some questions.

    1) Is there anyway to identify the block year? If this is the RXT-X '08 block then the oiling system for the new supercharger will be better.

    2) The '08 gas tank has a vent line that has a red plug but looks like a factory clamp securing it. So essentially no venting. Is this normal? The parts diagrams show a vent line with check valves. Installing a DW65C pump and want to make sure fuel tank is OK.

    Thanks in advance with any info.

    So there is no external way (visually or serial numbers) to tell and '07 from an '08 motor in the jetski?

    And everyone does or does not have a fuel tank vent ('08 specifically)?

    There is a tag on the front of the motor with MFG date. Either the tank has its own vent line or the fill cap is vented.

    My 08 GTI also has the fuel tank vent port and parts diagrams show it, but it's not used; same as the battery vent. There is a sticker near the gas cap that states something about "only use vented gas caps". I'm assuming that replaced the vent line.
