Type t fuel pump

Post by raybanky »

Hi Folks,

I'm having a problem with my 1937 Lanchester RoadRider type T fuel delivery pump.

I have checked the diaphragm and it is intact and in good condition and it delivers fuel to carburettor
when I depress the manual fuel delivery lever and I can keep the engine running but, when I stop manually
delivering fuel the engine stops.

Am I correct in thinking that the problem must be wear on the fuel pump camshaft arm?

Can anyone suggest a possible solution besides buying a replacement pump?

Please help if you can.

Ray B. :)

Hi Ray, sounds as if the actuating arm may have fractured, so remove the pump and take a look, I very much doubt that the arm would have worn enough to-enable it to loose contact with the camshaft.

Cheers Al :)

Thank you Al for your comments. I have had the pump off many times and can confirm
that the actuating arm is intact and isn't showing much appreciable wear.

I have been trying for some considerable time to purchase a replacement pump but, I can't find one!

If anyone reading this has a spare Type T pump for sale I would be delighted to hear from them.

I need to solve this anoying problem soon as I have classic car shows in the offing and don't want to miss them!

My thanks in advance.

Ray B.

Hi Ray,

I realise this is a very old message, but I'm having the exact same problem with the Type T pump on my LD10.
I'd love to know what you found and/or how you resolved the problem.
