Which Fuel pump when fitting WEBER 40's to Spitfire 1500

[Benlm77]

Just upgrading to Weber 40's on a fast road car and not sure which fuel pump to go for cylinder or cube, can anyone advise what the difference is (apart from the shape) and the pros\cons to either.

 

Thanks in advance

Weber do not need much pressure, 2psi should be fine. Just as long as the pump can flow enough. 

On a 1500 I would expect the std pump to be fine.

 

If you want a leccy pump, the cube facets are cheaper, for a reason. The red top pumps are superior. And remember to fit as low as possible in the boot, they are not meant to suck. And remember you may well need a pressure regulator as these pumps can put out too high a pressure for the webers.

 

Alternatives would be Huco, possibly facet posiflow, or a pump off a carb'd bike. All will be more than enough for the 100-110bhp I am guessing you are expecting.
