‘84 Velle has been stalling whilst driving along and at roundabouts. Sudden cutting out and recovering for very brief periods also.
I thought it was my Pierburg 2E3 (on 2.1MV). Wilbur lent me his Pierburg, but same issue. Changed the fuel filter, same issue, coil checked out ok, 1.5 ohms primary, 4.5k ohms secondary.
So, borrowed this £11 fuel pump and boom - problem solved.

So, the question is; I bought the £77 fuel pump in March 2019 from Brickwerks, it should be ok. I trust Brickwerks kit, we all do.
Q? Is it perhaps delivering too much pressure? Are Pierburgs sensitive to that?
Anyway to test it before I bin it?
Hard to imagine it’s already had it.
p.s. Just remembered. Few weeks back I changed my spark plugs; just regular service stuff. They were black, from running too rich, which suggests too much fuel being delivered.
