Ngh30 Posted September 3, 2017 Share Posted September 3, 2017 Ok , taken the tank out to clean and wax oil the chassis wk end , pleasantly surprised all solid . However on taking the tank out there seams to be what looks like a plastic breather non return valve mounted on the outside of the tank at the top (Pierburg ) that needs to replaced , Where's the best place to get one from ? It a k series engine . Thanks in advance Link to comment Share on other sites More sharing options...
Wrightpayne Posted September 3, 2017 Share Posted September 3, 2017 You might want to check if you have a charcoal canister in the engine bay. With the correct non return valve this can be discarded too. Search the archives for the valve details and 'how to' as you need to put a loop in the breather hose.https://www.lotus7.club/forum/techtalk/workshop-notice-371-fuel-tank-breather-which-way-aroundIan Link to comment Share on other sites More sharing options...
SM25T Posted September 3, 2017 Share Posted September 3, 2017 Buy an 8mm in line one way valve to allow air in to the tank for only £4 - £5 from car spares shop or on eBay. Link to comment Share on other sites More sharing options...

SM25T Posted September 3, 2017 Share Posted September 3, 2017 That will do. Prefer to use petrol hose clamps on small fuel hoses .... not jubilee clips ... they are not very round in small sizes. Link to comment Share on other sites More sharing options...
