[urq] Better fuel pump needed

Turns out one of the problems I’ve had with my Megasuirt EFI installation and tuning has
been a crappy fuel pump.  It limits flow and the engine was running crappy at 5k and now
is cutting out at lower RPM and even idle too – buzzing is very load.   Now this is the
third or fourth pump I’ve installed in this car.  The first pump was totally seized from
setting when I got the car about 5 years ago.  I purged the lines and flushed the tank
and installed a pre-filter.  I installed an 87.5 Coupe GT/Model 90 pump – higher flow
and pressure.  The first one was defective out of the box.  The second one is now acting
up.  Tank was just flushed and I routinely replace the pre-filters even though they look
clean, so I don’t think any garbage is getting into the pump.  

So I am looking for recommendations for the best pump to use since I no longer have CIS.
I would be nice to have the output fitting mate with the stock fitting, but mainly I
want a reliable high output and pressure pump.  The inlet is already using a larger
hose.  I’m tired of doing jobs 2 and 3 times, so this time I won’t try to skimp on cost,
although the ones I’ve been putting in a Bosch Replacements.

Recommendations?

Ben
