hi there i have a 1976 westfalia t2 which has had the engine upgraded by the previous owner to a 2000cc engine with twin carbs and electronic fuel pump, he told me the engine was from a t25 van... had the van since june 2012 have noticed fuel smell when walking around back of van and very strong when parked in my integral garage, even with fuel tank near empty and not having used van for a week or two i will still smell fuel...... i leave window open in garage and engine is next to up and over door which has a decent gap for air circulation as i also have a central heating boiler at the other end of garage.!!! i know i need to check all hoses and remove firegauard to check fuel tank.it has been sugested that the electronic fuel pump be replaced with the original manual fuel pump as it's pushing to much pressure in the carbs??? but if i did this would i get fuel starvation?? i know it could be a number of places it could be coming from, there is no leaking fuel just vapour smell. but what do you think about electronic pump? is it o.k , looks like it has a regulator (pro-flow y tec) use the van with my kids so need to get it sorted before i take them back in it. appreicate your thoughts rich35
Check the short length of hose that joins the steel pipes to / from the condensor up behind the spare wheel well.
My electrical fuel pump didnt cut off when the ignition was off so I put a mechanical one back and have not had any issues since. It was constantly flooding the engine.
Check there are no leaks anywhere in the filler pipe, neck and joints. If there is, fuel will get trapped in a compartment where you won't be able to get at it to wipe it up. Does the smell get worse on sharp left hand turns? Probably is the filler pipe if it does. Because the fuel's trapped though, it won't be dangerous (so long as it doesn't start seeping down the offside inner wheel arch onto the exhaust) but it will take a while to dry up naturally, meaning you'll carry on smelling it for quite a while after the filler pipe's been fixed.
As baysearcher said check the fuel tank breather pipes the joints tend to degrade with age and break up.
