[Mgs] SU Fuel Pump Question

Personally, I would stick with the SU fuel pump, repaired or replaced.
It may be quite a bit more expensive but they tend to be very reliable,
lasting through decades of service. Internal parts are readily available
and cheap allowing for them to be rebuilt rather than replaced (although
I opted to replace my last one). And they are quiet and turn off when
the lines reach pressure (float bowls are full).

I had the cube one on one B - it was noisy and pumped continuously even
when the floats cut off the flow. It lasted just a few years, to be
replaced by a SU. Plus you have to make sure it's a low pressure model
or install an additional pressure regulator to keep pressure below 4
(psi?). If cost is the major factor, the cube model may be good but in
the long term (10+ years), I think the SU would end up cheaper.

>From your description, it is not clear if the pump is installed on the
car
or not; and if so, if the fuel line is connected to the carburetor.

Thanks for the response.  Let me clarify:  The car sat for a year or so
and
once I drove it a few miles, the pump stopped.  I drained the gas tank
and saw
rust particles.  I took the pump off and on the bench without a fuel
feed the
pump clicks once.  Does the pump need primed for it to pump fuel?  I did
clean
the points.

My question is: Given the reliability and relative expense of an after
market
fuel pump, and the collective experience of the MG list experts:
Should I just install a NAPA fuel pump?

Thanks again,
