If it loses prime on level and uphill. I assume it does not when parked downhill?????
Start good on downhill is very good indication of return line issues.
There is banjo bold on back of head and a three way fitting nearby that can leak air into the line and cause drainback and hard starting. Next is the oring on each of the crossover tubes can detoriate and allow a leak... The leak is so small that fuel molecue cannot be forced out but the weight of fuel and a negative pressue in fuel tank as cools down can allow air to be pulled into return system.
The VP44 cannot deliver fuel to injectors until a slight backpressure (if you follow) is present in return system.These are the facts, Jack.
