    after some advise, only been on the road for a month or so and can smell fuel. Nothing over powering but finally looked under the van to find the below. Can someone shed some light.

    All hoses are fine from tank to motor. The part that looks like to have a overflow tube and also a couple of hoses in and out seems to be leaking some fuel??? I have a photo so hopefully it’s not that much of a major issue! Fingers crossed.

    But can’t upload photo argh

    Hi Jason, It looks like your fuel pump diaphragm might have a hole. This is located under the car on the RHS.

    That’s what I thought to be honest. Might just get the fuel pump replaced. Not sure if it’s a job I can do

    You might be able to purchase a replacement fuel pump kit.

    Jason,

    Look local

    Always has a VW of some sort in the shop - he has looked after Mr K for many years and I am happy with the service.

    Just so you know, new kits and fuel pumps are not available and haven't been for years. You might be able to find an old original one but Do not go for the Chinese copies, they have a very bad reputation. Most go to electric but you will need some extra cabling as well as a tachometric relay to shut off the fuel when the engine stops and a solenoid to shut off the fuel so it doesn't leak out through the carbs if the needle valves fail.

    Many threads on here about various options.

    I would also look up on Ratwell.com the fuel tank vapour breather system for the tank as I reckon you will find the smell is coming from one or more of the connectors in the system. Great diagram on there as well as the size of fuel hose required.

    Second what Adrian posted.
    And familiarise with it all yourself even if the mechanics do it.

    Not all mechanics know these busses. ;)
    Plus you learn to keep in top of maintainence.

    Scroll down a bit and you will see a diagram under heading FI fuel tank. The breather hoses are the same for carb. Most you can get to easily but the actual tank ones you will need to remove the firewall which is much easier with the engine out. The red one is a bugger to find and reach but is a very likely source of the smell.

    Ratwell is full of great info, but bear in mind there are some differences between the American buses and the Australian versions, mostly are in the EGR and Pollution systems.
