    Fuel/ Air Separator advice

    Hi,

    I've just had my carbs overhauled on my XLT1200, had everything done as per this thread:

    http://www.greenhulk.net/forums/showthread.php?t=70129

    While reading up on what to do I noticed Bill's twin fuel pump and fuel/air separator setup so I started having a look around for parts and there doesn't seem to be a supplier for them now, I understand why Bill had the two pumps (and that makes sense) but are the fuel/air separators required to stop the engine running lean? if so does anyone know where I can get one?

    Thanks for any advice

    Deker

    Give Carl at Island Racing a call. He still has them listed on his website.

    Group K also still has them too., I have them on 3 boats and they are a nice piece of mind especially if you like to run towards the low side on fuel level. Dual pumps are way overkill on a 1200, especially if not heavily modified. The pumps most guys and kits used were designed to supply 2 1100 or 1200 engines, not just one. I use the double ones on my 1390 because of a "take no chances" approach, but use a single on my 1200 XLT.
    Note: You should pull the carbs and take the check valves out of the pumps on the carbs, and it would also be a good idea to do the "restrictor mod" listed in the FAQ section.
    Note #2. If you do the restrictor mod you greatly reduce the chance of running lean from a fuel pump standpoint and may not need to do the air separator thing, especially if you are not modified. Three other boats in the family are done this way and it works well.

    Thanks for the replies I'll order one and fit it next time I pull the carbs off, they've just been rebuilt and refitted (with the restrictor mod) so I don't want to pull them back off straight away, I'll just make sure I keep above half a tank of fuel until I do them

    Air and fuel are pretty easy to separate. I use 1" copper tubing with 90s sweated in. Feed it at the top take it out of the bottom!

    Hi,

    Thanks, do you just run this with the stock pumps?

    Regards

    Yes. I run this on an Exciter 270. Both A/F separators cost about 20.00 ( I did the soldering and made them about 8"s long

    That is a lot sexier than my copper tubing but the same concept. I like your setup!
