Hi, I’m hoping someone out there might have a fix for a minor problem I have with my fuel tank.
I’ve been having ongoing problems with a strong smell of fuel from the tank. I replaced the breather pipes but the smell continued.
I have now dropped my tank to clean and seal it (rust issues) and have found what I believe to be the problem.
inside the tank there are 2 pressure regulating valve assemblies that are linked by a small 4mm metal pipe which then beaches off to the smaller vent pipe. I believe these prevent negative pressure (so allow air to be drawn in rather than out).
Both are linked with a crossover pipe which then branches off toward the external part of the pipe work, however there seems to be a small junction piece missing, per photo. Without this being joined the vapour just vents straight to the atmosphere!
Does anyone know for sure that there should be a junction / union at this point and, if so what material will be best? I presume submersible fuel line given the harsh environment it is in, however it only looks to be about 4 or 5 mm in diameter! Maybe nylon? Teflon? Silicone?
I’ve attached 2 images, one showing one of the valves, the other showing the void between the 2 sections of pipe.
Hopefully someone can assist!
BTW.....fitting will be challenging however I’ve made a super long set of long nose pliers (cut & shut) so I can work through the sender opening. Something like keyhole surgery!
