fuel pump

["Scott Hutchinson" <shutchin@netjets.com>]

I modified the 260 a bit.
 
Roller cam, f4b etc.
 
Runs beautifully but sometimes it seems like the stock fuel pump might not be 
keeping up.
 
Any one else have this problem?
 
Solutions?
 
I notice that the factory fitted the twin barrel SU pump when they went to the 
four barrel carb,  anyone know the model number?  
 
Thanks
Scott
