Getting the fuel system right on a 200tdi conversion

Afternoon,

Struggling with the fuel system on my series to discovery 200tdi conversion leading to rough idle and no power. I'm looking to remove all air leaks, as I currently have one at the union on the lift pump on the outflow. What are the best aftermarket unions that can have a clear pipe pushed on?

Would these work/fit?

8mm fuel tube and correct olives is what I used , tube fits over the pipe on the injection pump parts can be bought from here

Have you got the feed and return the wrong way round? Embarrasing to admit, but when I did my conversion I had these round the wrong way. The engine fired up and idled reved up but was starved of fuel!!!

Just a thought

take some pics and post them up

not quite related, but, i've had to wind the screw to increase the idle revs for my 200di as it was shaking the whole series to bits - it now idles nicely - all be it at a higher rev

Try some injector cleaner in the fuel Bump makes a difference to my 200DI , what is your exhaust gas like ie clean or what mine smokes if I give it too much welly , but ok if I accelerate slowly .Was terrible when I 1st fitted but added millers additive and it ran smoother then adjusted fuel pump to give less fuel and now runs quite clean and will do 70mph if I push it ,much happier at 60.

check your mount rubbers as well, esp if they are cheap third party
