justcallmemac Posted April 9, 2017 Share Posted April 9, 2017 Hi,I've recently had my R500D remapped.About an hour or two after a drive, once the car has cooled down, there is a strong smell of petrol but I cannot see any signs of a leak anywhere and there is nothing on the garage floor. Complete PITA as smell gets in to the house although it eventually disappears.Any pointers and as I'm a complete novice, please provide as much detail as possible. Cheers.

Jonathan Kay Posted April 9, 2017 Share Posted April 9, 2017 In no particular order: Do you think it's done this ever since the work? Visual inspection from filler cap to exhaust: filler hose, fuel tank, float fitting, pipes... do you have an Assembly Guide? If the tank (or anything else) is dirty give it a good clean and then inspect again. You can use bits of paper towel to check for moistness. Get someone else to confirm the timing of the appearance of the smell. Starting and running OK? Any visible emissions from exhaust pipe? Does it live in a garage or outside? How far are you from the remapper, and where are you?And the safety note: keep everything well ventilated, no naked flames, pilot lights, smoking etc and have a fire extinguisher somewhere appropriate.JonathanPS:Any pointers and as I'm a complete novice, please provide as much detail as possible."We are all complete novices, but some of us are looking at the stars". :-) Link to comment Share on other sites More sharing options...
justcallmemac Posted April 9, 2017 Author Share Posted April 9, 2017 Looks like a leak at the fuel tank end. Noticed a few drops of petrol on the corner of the frame directly underneath the offside edge of the fuel tank, which had just started to drip on the garage floor. Had a good look around the filler cap, hose and filter assembly but they were spotless and from underneath, around the seal gasket but couldn't see anything obvious. Had a clean up anyway but evidence of the leak soon returned in the same area.Unfortunately I can't easily identify where the fuel is coming from with the tank in situ but I suspect the gasket might be an issue and it seems a pig to get to. Looks like a tank removal jobbie unless anyone has any easier solutions. Link to comment Share on other sites More sharing options...
Roadsport06 Posted April 9, 2017 Share Posted April 9, 2017 Have you checked the sender gasket at the top of the tank below the boot floor? Link to comment Share on other sites More sharing options...
Jonathan Kay Posted April 9, 2017 Share Posted April 9, 2017 Well done. I've never changed mine: does the tank have to come out?Useful notes. And there are some suggestions to change the fuel filter while you're down there.Jonathan Link to comment Share on other sites More sharing options...
Markiebabes Posted April 10, 2017 Share Posted April 10, 2017 I had a small weep from the petrol tank hose (perished under clamp ) that comes out of the tank only noticed after car had run up to temp,assume it was under pressure ! Check that hoseTanks can get pin holes !When I first got my car I had this and tank was replaced under warranty As above sender gasket worth a lot also Link to comment Share on other sites More sharing options...
john milner Posted April 10, 2017 Share Posted April 10, 2017 Sender gasket is a fairly common problem so I would start there. Link to comment Share on other sites More sharing options...
