mahatma Posted March 8, 2004 Share Posted March 8, 2004 After converting to throttles (k series), does anyone know if I need some sort of valve or breather filter on the fuel tank breather line (instead of the charcoal cannister breather thing)? If this is something I should use, could anyone recommend a part ? Thanks Andy Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted March 8, 2004 Leadership Team Share Posted March 8, 2004 Andy, keep the same setup as the car was running before when it was on a plenum. Stu. Link to comment Share on other sites More sharing options...
mahatma Posted March 8, 2004 Author Share Posted March 8, 2004 But the piping for the charcoal cannister (to the plenum) has now gone, except for the fuel tank breather ... i.e the cannister now has two spare pipes on it, not connected to anything. I wasn't sure if I could just ditch the cannister and run a bit of hose from the 'breather pipe' and let it vent to atmosphere or if I should have some sort of valve or filter on it to stop crap getting in ?

Leadership Team SLR No.77 Posted March 8, 2004 Leadership Team Share Posted March 8, 2004 If the breather was previously going from the tank to the plenum, via the cannister, then it would still be possible to breath into the TBs if there is facility to do so, otherwise breath to atmosphere. If you do breath to atmosphere, run the breather pipe vertically then do a 90º turn to head back down - should stop the afformentioned crap. Have a chat with Mav about this setup. Stu.

mahatma Posted March 8, 2004 Author Share Posted March 8, 2004 Cheers Stu, been talking to Mav and we though we had a valve sourced from DT ... but it looks like it may be a one way thing and I reckon it needs to be two way - so that air can get in and vapour can get out (to stop the tank expanding and contracting).

Strangely Posted March 8, 2004 Share Posted March 8, 2004 This was covered recently here: http://blatchat.com/T.asp?id=47994 which links to here: http://blatchat.com/T.asp?id=39397 which links to here (PDF): http://www.graduates.org.uk/racing/Fuel-tank-notice.pdf This includes details of the parts (including valve) that you need to order from Caterham.

mahatma Posted March 8, 2004 Author Share Posted March 8, 2004 Thanks Strangely, missed that one first time around - looks like just what I need. Cheers Andy Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted March 8, 2004 Leadership Team Share Posted March 8, 2004 It's not a Caterham instalation but it may help. Link to comment Share on other sites More sharing options...
Strangely Posted March 8, 2004 Share Posted March 8, 2004 Hi Stu. What do you mean? The document wasn't produced by Caterham, or it's not for a Caterham? I can't comment on the former, but I followed the instructions just about exactly, and bought the hose and valve from Caterham. Seems to have worked well.

Pierre Gillet Posted March 10, 2004 Share Posted March 10, 2004 Good question. Also, with such valve is there still a need to make a loop with the rubber hose? Pierre Link to comment Share on other sites More sharing options...
