Weber Pressure Rating

[burr_2000 1]

Hey guys need some advice. i am running twin weber 40 DCOES on a 1.4 106 xsi. Does anyone know the recomended fuel pressure needed. Been reading through some different forums and weber themselves. Some people say 2 PSI is right and some people recommend at least 4 PSI. I need to buy a fuel pump so dont want to buy something thats over the top.

I think if you run them too high they start to froth and leak.
