se5a fuel pump

Post by tony1966 » Wed Jul 24, 2019 9:33 pm

hi folks,the se5a i just bought has been fitted with an electric fuel pump[facet type] beside the tank and a regulator beside the carb

it has a new looking mechanical pump fitted to the block[nothing connected]

car runs fine with the leccy pump so i might blank off the mechanical orifice in the head

can folk tell me what the fuel pressure should be for the v6 on its standard carb so that i can check it-and do they run better with mechanical or electric pumps as a general rule...thanks in advance

You need to limit the pressure to about 3 psi. Cheap regulators are a waste of money, I would recommend the Filter King.

There is no point trying to teach a pig to sing. It doesn't work and it annoys the pig.

Millions of engines, inc the V6, have run around for years without problems with the standard mechanical pump. :?
The only "GOOD" reason for fitting leccy, in my opinion, is to fill the carb if the fuel is left to evaporate. :lol:
Be this because of heat evaporation, OR on cars stood for long periods. :?:
OR if your running a heavily modified engine and it requires gallons of fuel to keep running. :w
