Hi all,

I am about to ask a really newbie question and I apologise in advance, its concerning elements in the IP. I know that my stock OM606.962 engine has 6mm elements.

Here are my queries:

Am I correct to say that the elements are the parts sticking up on the top of the pump which connect to the individual fuel lines to the injectors?

Am I correct to say that the diameter of the hole the fuel flows through on my pump is 6mm?

Am I correct to say that there is a plunger inside the element which then gets pushed up by the pump internals which then sends the fueling through the lines?

Upgrading the elements from a 6mm to an 8mm element would mean that the element would have a 8mm diameter as well as matched with an 8mm plunger - or is it just the diameter at the top of the element that gets enlarged and you can run stock plungers?

I only ask as I know someone who is a machinist who has various lathes etc - I was wondering if it were possible to simply get a set of stock elements and modify them by enlarging any ports and then machining slightly larger plungers if needed?

Sorry for the newbie questions, I know that some people have done a DIY swap of the elements but all I can see is that the element is held at the top of the pump which might mean that if they are kept in the same order they might not need calibrating?
