alan_k Posted May 10, 2010 Share Posted May 10, 2010 Has anyone fitted dry break connections to their fuel line, so that the tank can be removed easily Would these type of fittings be suitable http://www.demon-tweeks.co.uk/Motorspor ... /1646/2821 I'm not familiar with the 'End Fitting' types, is 6mm push on suitable for 6mm ID hose If you look at the flow rates under the different series they're a bit mind boggling for a paramotor Cheers, Alan As an aside they also do Fireproof Underwear for those radical moves Quote Link to comment Share on other sites More sharing options...
Farmer_Dave Posted May 10, 2010 Share Posted May 10, 2010 It's fitted as standard to mine Alan. Pretty handy. The one way vent is great too. They should be a standard on all I reckon. I've heard of a few who forgot to vent their tanks and subsequently lost power. Quote Link to comment Share on other sites More sharing options...
Guest Posted May 10, 2010 Share Posted May 10, 2010 Alan, The 6mm is the OD size of the hose yes. They are great fittings and at the cheeper end of the motor sport ones out there. Also Google Hel Hoses ( a great British company), who will put together whatever you ask them to, used them loads when drag racing, and for our Carbon Fibre stuff.

Dave Hummm, I though that it was a euro law that all petrol tanks had to be fitted with a PVRV ( A pressure vacuum Relief Valve) The Parajet has one built into the cap it's self as do most as far as I know.. If people are getting problems because of not 'venting' they should be looking for the real problem (a blocked PVRV) SW Quote Link to comment Share on other sites More sharing options...
Farmer_Dave Posted May 10, 2010 Share Posted May 10, 2010 I think there's one of those in the cap Si. The vent I refer to automatically let's air in but wont leak fuel out. Just one less thing to worry about Dave Quote Link to comment Share on other sites More sharing options...
outkast Posted May 10, 2010 Share Posted May 10, 2010 always used one of these when racing,has a small ball bearing inside wich of orientated downwards would seal the fuel from leaking. http://cgi.ebay.co.uk/NEW-RFX-MOTOCROSS ... 439d057dba Quote Link to comment Share on other sites More sharing options...
flyingdoc Posted May 10, 2010 Share Posted May 10, 2010 Alan, That link page is pretty confusing, which actual valves are best for the normal fuel line? Quote Link to comment Share on other sites More sharing options...
alan_k Posted May 11, 2010 Author Share Posted May 11, 2010 That's why I put the post up Paul because I don't know either I have never used these before, I think it's probably best to phone up and talk thru you're application, specifying the fuel hose size. Cheers, Alan Quote Link to comment Share on other sites More sharing options...
Guest Posted May 11, 2010 Share Posted May 11, 2010 The best option is to get the hose from the same person and replace that as well, if they supply it. Some 'quick' connectors will allow for silicone or plastic (semi rigid) hose, where others will only work with the semi rigid stuff. So in a nutshell, it's not just the size of your hose, it's how stiff you get it :-) SW Quote Link to comment Share on other sites More sharing options...
bendmeroundthehedge Posted May 11, 2010 Share Posted May 11, 2010 Halfords do plastic quick connectors (for motorcycles). Whichever ones you choose, try to get the ones with Viton O rings. http://www.colder.com/Home/tabid/36/Default.aspx Quote Link to comment Share on other sites More sharing options...
fanman Posted May 12, 2010 Share Posted May 12, 2010 Those would appear to be the ones that Bailey use as standard. The only thing that slightly concerns me about this thread is that you must be aware that if you have a diaphragm fuel pump it is vital that this connection must seal perfectly and does not allow any air into the fuel system. Not an issue if you have a float carb. Quote Link to comment Share on other sites More sharing options...

bendmeroundthehedge Posted May 12, 2010 Share Posted May 12, 2010 Most quick connectors use Buna O rings. Problem. Eventually they swell slightly making it harder to dis-connect/re-connect resulting in eventual damge/failure. Sorry Alan, no part numbers, just noticed them when picking up some oil. The following links give better options. http://www.tom-parker.co.uk/products_su ... roups=899A http://www.tom-parker.co.uk/products_su ... roups=897A Quote Link to comment Share on other sites More sharing options...
alan_k Posted May 12, 2010 Author Share Posted May 12, 2010 Thanks for that Kev, I think the 897A group is the same or similar to the connector used by Bailey. Just the job, Cheers, Alan Quote Link to comment Share on other sites More sharing options...

whitcombe Posted May 14, 2010 Share Posted May 14, 2010 Guys, I have took a leap of faith and just ordered one. Dont buy them from demon tweeks though as they are £14.99 and they want £7.50 postage Just copy and paste the item description into ebay and I got one for £13.99 plus £1.25 postage They look like they will do the job as long as they dont let in any air as they will be working under a slight negative pressure from a walbro pumped carb. Saying that I used to use festo pushfittings on my model jets for fuel and air systems and never had any issus under negative pressure ? Will let you know Tim, the welsh radne mad professor....IT'S ALIVE !!!! Quote Link to comment Share on other sites More sharing options...
