Mk 2 Ruby fuel pump

[Joe eck]

I believe the arm numbers quoted on the old ASF Forum were as follows:

856955 is the correct one.

1524079 will also operate perfectly well it's alleged.

Complete new pumps - though not I believe arms are available from the Seven Workshop - link below

Thanks Jeff , I will check my part number and , if incorrect , I shall seek a replacement.

The pump came with the car which had no engine so I assumed ,
 Possibly incorrectly , that it was the right one !!

If anybody has a damaged or un useable pump with the correct arm please let me know.

I will refrain from using the car until I put this problem right ; don't want to cause any major damage.

Thanks again.
Joe.

Having checked my pump , it appears that I do in fact have the correct operating arm ( thanks Jeff for the info )  . 
I can only now assume that the replacement screw that I have fitted in place of the original broken one is holding the arm slightly too far back to ride on the rear of the cam eccentric.
The original hardened steel screw had a turned down end and it is the turned down section that has broken off.

Has anybody any idea where I might obtain said screw before I resort to a replacement pump ?

Thanks
Joe
