I've been using just that...the Purolator dead head
regulators. ...round, one big dial.
...got 'em on my Midget, MGBGT and even my Spitfire
(which has a mechanical pump.)
J.C. Whitney has them at a good price. I usually
buy them 2,3 at a time.

ignore the casting numbers. They are not direct LBS
settings. Use a gauge to set it.
With a pressure gauge on the carb side of the pump
I've seen the standard elec MG pump put out 1.5lbs
and as much as 6 lbs. It all depends on the
condition of one spring inside the pump.
Before setting the regulators (on most SU's I've
found 2lbs (3lbs max) works best almost across
...at least in my experience.)
I like to check the min/max pressure the pump is putting out
and then set it at a max of about 2.5 lbs. steady reading.

One post said 2.5 to 3 PSI and Paul says 1.5 to 4 PSI. I used my
Crapsman pressure and vacuum gauge and the fuel pump puts out about
3.75 PSI. Is that in range or a bit too high? If the gauge is off by
10% the range could be from 3.375 to 4.125 PSI. What do yah think?
If the pressure is to high who makes a good small pressure regulator. I
remember the ones when I was a kid, they were made by Purolator and
they were big and had a dial to set the pressure. Anyone found
anything better for a Spridget?
Maybe some junk getting past the fuel filter and causing the floats to
stick?
