Hive just installed a new fuel tank on my 90 diesel since doing so when left over night it's a pig to start in mornings like fuel is leaking back through any ideas what it could be ? I've checked connections and pipes on injectors
Check the joint and gasket on the fuel return connection to the tank, also check you haven't kinked any of the pipes where you changed the tank, might have caused a very small split letting air back in.
