ive got a Volvo 460 which is actually running a renault 1.9TD engine, so i thought this would be the place to ask. i want to change the Lucas/CAV diesel pump for a Bosch one but dont know which one would be a direct replacement, if there is one at all. please if anyone has a renault 1.9TD with a Bosch pump or knows of a web site with comparison details could you post. thank you very much for the info in advance.
