Electric Fuel Pumps
Posted: Sat Feb 04, 2017 2:26 pm
So the first thing that got the toss when I did the carby turbo conversion was the mechanical fuel pump. I went on eBay and bought a little Pierburg external pump which pumps at 8lb. Bolted it into the engine bay ,fitted a pressure regulator, then basically forgot about it. That was 15 years ago.
Which got me thinking.. how long do these little buggers last.
I know what happened when my VN Commodore fuel pump shit itself, and it was only 5 years old.
I was on a 4 lane highway, in the fast lane. So an instant loss of fuel pressure meant instant engine shutdown, no power steering and only a couple of brake applications before the brakes would be useless. I manged to maneuver between trucks and cars and find a nice spot next to a breakdown phone.
So this morning I was looking at the Pierburg in the Sigma and wondering how long it might be before I should replace it. Waiting for it to fail might not be the best option.
