thanks. i'm running that pump at the moment with the matching carbs with no problems but will soon be swapping to weber'd pinto which i
think may well need more pressure than 1.5psi

If it helps Mr Haynes says that the fuel cut off pressure for the pump is 1.6 to 2.3 psi.

cheers 
going from bike carbed 1700 x-flow to 2.1 pinto on 48's. i was presuming/knowing they'd be needing a facet & reg really but was just
wondering if i'd get away with the current one as would save some more aggro!!!

I have heard that webber 48's can be too much for a pinto.

48's for a race Pinto, no need for road or the odd track day, 45's will be fine, 40's will work.

It's the choke sizes that are important
