C.A.V. Injection Pump 680 Leyland Atlantean Double Decker

Postby alex117 » Sun Oct 21, 2018 5:12 am

While trying to bleed my system of air I put Diesel in the pump where it should havexxxxxxx???. I have looked online for some sort of manual for pump without luck I do have the Atlantean manual but is only has limited information about pump . I have read the manual and bleed out the air but it still will not pump fuel out of the top when I disconnect the injector line from top of pump so engine will not start.

Update: Plate on inline injection pump: CAV DES Type N then stamped in centre top of body of pump 1097

There is a large plate in the centre of the pump held by the bolts

There is a filler plug as well , behind this is the springs for the injectors

What is the purpose of the filler plug? Is it filled with fuel?

When I pump the lift pump fuel comes out the bottom where the springs are?
