  • Fuel pipe replacement, car peed on the floor

    Car peed on the floor…




    It’s a bit drippy here at the back, but also at the front on to the start motor – not overly safe and smelled pretty strongly of fuel.




    The main leak is here at the back between the hardline and the hose. The hoses have gone quite hard with age. There is a flare on the copper pipe.




    All the fuel hose is 12-14 years old, this was visually the worst – the main pick up pipe, which is most exposed to the elements. The rest hard gone hard but were not cracked yet.




    Emptied 25ltrs of fuel out the car using the Power Probe – all power disconnected on the car, hooked the probe up to the battery and switched 12v on the the positive side of the pump. Drained the tank very quickly into fuel cans.




    Brand new hose up front for both the feed and return. Although these pipes all looked OK it was worth changing everything while the fuel system was drained.




    New pipe from the tank to the first filter, to the pump, the next filter and then down the copper pipe where it was leaking. Also replaced the return rubber line.




    Here are the rest of the old pipes that when in the bin, these had gone pretty stiff especially when compared to the new pipes.




    All back together again! Used the power probe to prime the whole fuel system and check for leaks before starting the engine – fired up instantly, no waiting for the fuel pressure to build up when you prime the systems.




    If you're going to do any work on rubber hose, this tool (HCA25) from Sealey is invaluable, cuts nice straight ends every time!

    I have had fuel pipes and other things perish. It’s not always possible to tell how old the stock is when you buy it. Particularly from eBay.

      This appears to be a common problem.
      Your hose marking looks similar.
      I now only buy premium quality hose from an OEM supplier like Cohline.
      Glad you found it in time and didn't have a major fire!

        I would echo that. The higher ethanol content of modern fuels may be responsible for multiple fuel issues, whether tank, pump, hose or filter issues.
        Certainly I would purchase direct from reputable suppliers, Burlen Fuels come to mind, for ethanol compliant products, a company with a proven track record much better than eBay products from China, where there is little or no quality control or traceability.

          This is the hose I got this time, it’s marked as E10 compatible.

          This black neoprene hose features a single textile braid reinforcement and is suitable for use with the following fuel types - unleaded, super unleaded, leaded and diesel (compatible with fuels containing up to 10% ethanol). The hose has a working pressure of 150 psi so is suitable for use on both carburettor and fuel injected cars.British Standard Au108 approvedSold per metre and in one continuous length where possible. Bore Outer Diameter 6mm (1/4


          plus a little bit of OEM supplied BMW in tank fuel hose.

          The fuel smell was pretty darn strong so I didn’t get very far out the drive way before heading back in! I’m surprised I didn’t get more smell in the garage, but then I guess the pressure will drop off when the pumps not running if there is hole.

            I can recommend Terry's from Glencoeltd . He supplies Cohline R9 hoses that are ethanol resistant and will be a genuine hose . Here's a link : https://www.glencoeltd.co.uk/cohline...-low-pressure/

              Could not agree more. Recent experience with 2 [no, I didn't learn...] Chinese-made rubber items.
              First was a new clutch cable for a motorcycle. Five months after fitting it carefully - found the rubber 'boot' split even though not used and parked in a dark shed.
              Second was when two new anti-roll bar links were fitted when preparing a car for MOT. Change of plans meant project stopped so a year later I came to remove them for potential re-sale. (Car never moved)

              Found both had split their rubber boots - so scrapped along with car. Moral is "Watch out for anything made in China"

              I reckon China is superb at making good-looking replicas but too often the material quality is lacking.
