MF65 fuel lift pump identification

[mf65ro]

I have a 1961 MF65 (english built 765) with Perkins AD4.203 engine.

Recently I changed the o'rings for stop and throttle into the injection pump. After that looking up into the lift pump bowl, with the engine idling, I can see some air bubbling. Also after I stop the engine and start it after some time I can see how the pump spits out oil (it seems that is mixed with diesel), which makes me believe that the diaphragm is compromised.

On the lift pump housing is written "AC , Made in England , Patented" and under the pump body near one of the screws I can see 771 F4 . Can you help me to identify the serial number ?

Can you suggest me a new good pump?

Thank you all very much for your time,

Can not answer your question, but read somewhere about serious damage to a camshaft caused by a cheap repro lift pump supplied by a main dealer. The type that has multiple plated pressed together to form the cam follower arm. Apparently it gouged a groove into the camshaft in an hour or something, requiring an engine rebuild and replacement camshaft.

Hello,

Thank you all for your reply,

I found a Sparex pump https://www.malpasonline.co.uk/itm/Fuel-Pumps/Fuel-Lift-Pump/40560

What do you say about their quality?

I am in the process to buy an "AC Fuel Pumps Catalog 1929-1963" to identify the actual fitted pump and maybe one day to find a NOS AC pump on ebay.

Thank you all
