No. That is a db4. Fully mechanical. Like the db2, but uses 4 plungers instead of 2.
Desired for high rpm increased fuel output- aka makes good hot rod pump.
The problem with db4 pumps is when it wears it has a worse time idling and low rpm becomes choppy. But that doesn’t happen until over 150,000 miles. So again classifies as a hot rod pump. They were really intended for marine (boats) use.
