The pump was already installed when I bought the car.
As far as i can tell from the service log , It was fitted some years back following an engine fire caused by..... yup.... a leaking standard fuel pump .
The pump is fed by a relay that takes its current from the b+ on the starter motor, and is activated as far as i can tell , along with the ignition (15).. a very straight forward set up, but not the safest in a crash.. as it will keep pumping fuel as long as the the ignition is on.
I believe Anders has written a page about wiring up electric fuel pumps?
Anyway. my engine bay will not look like this for much longer, as I have collected these parts during the last couple of months :
45mm throttle bodies and assorted goodies
At first my plan was to have an inlet manifold made by a "mate of a mate" but he took too long, and the intake "roar" would have been lost.. and i really love that sound.
So I ended up with buying these in stead ... .. It should improve the fuel consumption quite a bit (my car has AT NO POINT done more then 9km/l.. and usually does about 7-8).
I reckon the gasoline smell will disappear as well.. and as a final bonus, the TB's are shorter(8cm in total) then the carbs allowing for deeper ari filters, and even some (very short) air horns/trumpets.
I don't expect much with regards to power.. thought the more accurate mixture will probably yield a few hp, for as Roy has said.. very few have gotten the twin carbs to run perfectly on murenas .. and I know ,as does any body that has ever heard my car approaching (and that would be
everybody in the general area) that my car is running.... slightly
rich In fact one could speculate , that if you took a really really modest car, like, say, a petrol Lupo, or Yaris, and drove it right behind the exhaust of my greedy eel , the small critter would be able to run on what my car breathes out.
