Ult-jim7 Posted July 13, 2023 Share Posted July 13, 2023 Hi all, have a leak in my braided fuel hose, believe it's the return leading from the front end of the fuel rail back to the fuel pipe to the fuel tank. I'm pretty basic with a spanner, so do you take off from the forward end of the throttle body where my fingers are pointing or from the connection marked with a red arrow? Any advice is much appreciated. Link to comment Share on other sites More sharing options...
SM25T Posted July 13, 2023 Share Posted July 13, 2023 Undo the two screws and catch the o-ring inside. Disconnect the other end of the hose. Cut carefully through the crimps and pull hose end fittings out. Replace rubber hose with 8mm bore fuel hose, doesn't need to be braided, and refit with proper fuel hose screw clamps Link to comment Share on other sites More sharing options...

SM25T Posted July 13, 2023 Share Posted July 13, 2023 What is the blue connector just below the braided section ? Link to comment Share on other sites More sharing options...
SM25T Posted July 13, 2023 Share Posted July 13, 2023 If you carefully saw or Dremel through the shoulder of that swaged crimp you can prise it apart with a screwdriver. There will be a barbed hosetail inside which is perfectly reusable. Link to comment Share on other sites More sharing options...
Englishmaninwales Posted July 13, 2023 Share Posted July 13, 2023 On removal, be prepared with absorbent rags/ paper towel for fuel to come out until it has depressurised. Also I disconnect the battery prior. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted July 13, 2023 Leadership Team Share Posted July 13, 2023 #4 The blue "connector" looks like a simple section of cut silicon hose fastened to the braided hose to avoid chaffing other components? Link to comment Share on other sites More sharing options...
Ult-jim7 Posted July 13, 2023 Author Share Posted July 13, 2023 Thanks for all your advice. Yes, lots of paper towel and gloves at the ready, and the battery was removed completely. The blue piece on the braided hose is a nice fitting piece of silicone hose acting as a chafe guard as it sweeps around close to the oil pump, etc. The other end of the hose comes off easily.

oilyhands Posted July 14, 2023 Share Posted July 14, 2023 Just for info, that is the main pressurised feed rather than the return so it needs to be resistant to the pressure (stock fuel pressure is 3 bar/44PSI).Oily Link to comment Share on other sites More sharing options...

7 wonders of the world Posted July 14, 2023 Share Posted July 14, 2023 Gates R14 grade fuel hose - no issues with Ethanol fuel etc then, and use double ear Oetiker clips, (O clips) for refitting, Also worth replacing the rubber fuel hoses at the rear of the car to whilst you at it, Link to comment Share on other sites More sharing options...
SM25T Posted July 14, 2023 Share Posted July 14, 2023 1.5m is enough for all 4 flexible hoses. Check fuel tank sender gasket too Link to comment Share on other sites More sharing options...
elan_fan Posted July 15, 2023 Share Posted July 15, 2023 I used codan R9 hose which is for fuel injection pressure R14 is listed as unsuitable for injection pressure Link to comment Share on other sites More sharing options...
7 wonders of the world Posted July 16, 2023 Share Posted July 16, 2023 R14is the grade of rubber (E85 compatible) and can be bought in low pressure and high pressure versions as can R6 and R9Gates Barricadehttps://www.opieoils.co.uk/p-244899-gates-barricade-injection-hose-27340.aspxIt Can be obtained in smaller rolls for much less, worth a few owners splitting a roll between themPhotos of the hose: Link to comment Share on other sites More sharing options...
