just bought a 1998 rover 4 series diesel turbo, been fine for a good copuple hundred miles but now has a prob, will go fine for ages but say jump on a motorway it gets realy sluggish and slows gradually, i pull over it dies, turn over to restart cranks and struggles and then fires up with foot to floor and is fine again!!

i noticed when idling the manual primer for the fuel system was colapsed as in sucked in and slowly filled out when car was switched off, thats not right is it? is that my problem? fuel starvation? it has a new fuel filter on it

Blocked fuel tank breather?

stringvest

that was my thought so i loosened the filler cap and drove it, still does it, it only seems to do it at speeds of over 50 roughly, i spose due to the vast demand for fuel

Is there a filter in the tank?

Blocked, kinked or damaged fuel line?

pugoetru

you have a blocked fuel pipe or a kinked pipe there is not a filter in the tank

if the fuel primer is on top of the filter housing then it could just be a clogged filter


edited to add

it does not matter what speed you are doing the fuel pump sucks the same amount of fuel it just varies how much goes back to the tank
although g forces may have an effect on fuel flow

SORTED IT!!!! yippeee

dropped the tank to check for kinked hoses but there were fine, pulled hose off that runs to front, disconnected at filter end at front and blew airline down it was bloked, pulled off the primer and hose etc and tried hose again with airline and was free"!!! the one way valve etc in the primer was clogged solid with crap, cleared out replaced and perfect!
