[T2] What electric fuel pump?

[Squid]

Hi, I have 1.8L with twin Del 34s, and an aux electric Mr Gasket #42S fuel pump.It does not supply enough fuel pressure to get fuel past 'flow metering' valve, and then to carbs.  It works as it is supposed to..just not enough flow..so..is there someone else on this list who runs Del 34s, and what fuel pump or system they use?  Thanks
