electric petrol pump

I have installed an electric petrol pump. At the same place were the mechanical was installed. but it seems like there will be no gasoline in the morning. the engine is running then he throttles out.
but it already makes tak tak tak, very little. as if the carburetors are full with petrol.

what is my problem ???

It may be the reserve petrol tap. The rubber o ring degrades and disrupts petrol flow.
 
What brand of pump is it Jorgenson? From your description, is it a Facet? Pumps are either pullers or pushers. If you have a pusher in the place of where the pump should be a puller, then it won't work properly at all. A pusher pump needs to be fitted underneath, typically beneath the fuel tank.

133010 is a puller - should be fine under the bonnet - probably want to not be too low down. They do need a regulator though or they flood the carbs by forcing the fuel past the float needle.
 
If i google the Hitachi pump, i see these look identical to the Hardi pumps. I use one of those (Hardi) without regulator on my Rover P5B. I think it are good pumps. I fitted mine underneath the car near the reserve tap

As you can see listed as a suction pump.

I spoken with a few other people about the regulator thing. It seems the output of the pumps can be spikey. Some people have been ok without the regulator, some havent. Seems that the spikey delivery pushes past the float needles when it pulses. Did on my car anyway.

I set the malpassi regulator so it doesnt restrict the average flow, just smoothes out the peaks and troughs and this stopped the carb overflow issues.
 
I am not familiar with the exact V8 set up with the return, is that taking too much fuel back to the tank, is there a restrictor somewhere ?
 
I seen to recall the restrictor is incorporated in the end fitting of the return pipe.
Not splitting hairs - it's at the tank end of the return pipe and the 'ole is quite small and easily blocked.
 
Yes there is a restrictor on the return pipe and its only 6mm to boot on the return.

The fuel needs to deliver only enough to supply the pseudo reservoir that supplies the float chambers without there being enough pressure to open the needle valve.
