How To Fix an Injection Pump (Simms Injection Pump) Part II 

The only tools I used was a delivery valve socket and allen wench socket.. You may can find the delivery valve socket locally somewhere. I got mine off of Ebay from the U.k. I also use parts cleaner. I didn't have to replace anything. I just took it apart and cleaned it. If you need any parts - I found them on Ebay as well.

Thank you

Yes Sir

It didnt show you using delivery valve socket i undid all the alen screws but couldnt pull the top free. Was there something else i had to undo sir.
