Pump has been played around with (max fuel screw and the top screw on the mushroom bit)
Running on veg oil

Cold starting problems veg oil check glow plugs are working by removing them and putting power to them 
Hot starting problems again the glow plug thing
Lots of black smoke when foot is down to much fuel turn it down 
No power
When I start my car it misfires with a ploom of white OR black smoke although it is more often than not white. white is unburnt fuel same as black is partially burnt fuel 

When running and up to temp it still misfires. see next bit in bold 
I have a boost guage fitted and it reads 22psi with 50% throttle (this is unusual as It used to be about 18psi)

I believe the pump is leaking air into the fuel beacuse it bunnyhops down the road at low revs. check for air ingress out a clear bit of pipe from fuel filter to pump and from pump to tank retuen to determine where the air is getting in. this will also a effect starting as well. 

all the connections on the fuel system I have made are tight and good with no air in the fuel. how have you confirmed there is no air in fuel as you are saying all the symptoms that would indicate so 

Thanks Dan
