Hav put a s1 vn v6 into HZ tonner and have begun have fuel pump probs (very loud noise from pump).
I left the original tank and installed a high pressure inline pump.
I think the prob is not enough fuel as there is no low pressure pump (or swirl pot) up to the high pressure pump.
Anyone have any thoughts. They would be muchly appreciated.
Yeah, you will need the "fuel tank" fuel pump, this will be the problem. can you fit a VN tank to the HZ?
Put a low pressure external pump and swirl pot in and you will have no more problems!
Make sure the low pressure pump can supply around 120l per minute or you will still have the same starvation problem.
