Here is a page with lots of Lucas links.

 

I had a few apart years ago, because they get dirty inside. I think all of the rollers and spacers were loose and had to be stuck back in place with a bit of grease. They ran on hard strips in a an aluminum casting. They were trouble free in operation as was the whole system. Remarkable for anything Lucas.

 

Probably because no electricity is involved. Kinsler still makes parts for the pumps and whole new pumps. The Kinsler stuff is for CanAm car and 5000 car restorations. Modern sprint cars usually use Hilborn. No slide throttles involved.

 

Here is a picture of a  slide set for a Cosworth engine. My first experience was with a Brian Hart Ford Twin Cam engine. It blew up when one of the precision British aluminum cast heads colapsed and dropped a piece of intake runner into a cylinder. I sold the injection to a guy in NewZealand. You might find one at a swap meet cheap if the seller has no idea what it is. Racing Beat used to build a two hole slide set for their engines. I wouldn't be shocked to find out they had one laying around

 

The electric pump is just to start the engine. The belt driven pump is for racing, and the electric pump can take over if a belt breaks or flys off.
