Mine takes about 3 seconds to start, but only the first start in the morning, it starts pretty much straight away after that, even if left for a few hours, almost as if their is a slight leak somewhere letting in air/ or fuel draining back to the tank ?

Hi

Unsure if this will be useful , but I found the supply fuel line going to the FBH leaking on a small push fit connector tucked away on the passengers side

Don’t know if the LP fuel pump serves both the engine and FBH fuel line and if it could ever allow air to be sucked into the system through the connector and put air into the engines fuel line prior to the HPFP ?

I recently replaced the LPFP and there is a supply for the FBH from there.
Starting got harder and harder then got low power mode then no start at all.
