hi to all
it started when t4 said there was a intermittent low fuel pressure so I tested the under bonnet pump and the fuel pressure was low so I bought a new pump this did not solve the problem so I tried this I disconnected the in tank pump and started the engine it ran and t4 said the fuel pressure read 390 kpa with the in tank pump connected with the pump disconnected it read 360 kpa so the in tank pump is only producing 30 kpa as I see it and rave states that the in tank pump should be 2.5 bar which is 250 kpa and the under bonnet pump should run for 20 seconds that is why and I am trying to find a way of testing of how much pressure the pump does exactly produce
