I'd say the Walbro is the 'gold standard', but there are plenty of others out there. If you could get into your header tank, or have room for an additional small 'sump', you could try this type:
(Not saying to use a $12 pump; just this style of pump.)
I considered this style for my in-tank pumps, but they must be mounted vertically, and would have interfered with the float of the fuel level sender.
Variations on this are in almost all new cars, but in the gas tank. That one is ~1.5 inches diameter & ~4.5 inches tall. Supposed to draw around 4 amps, so likely to be lower flow than any of the gerotor pumps. Walbro makes one that's about the same size, for typically around US $80-$90. They're turbine pumps, so the bottom must be in fuel to prime. No easy way to attach an input, except the purpose-made filter sock.
There are complete after-market assemblies (single pump, filter sock, surge housing, 40-240 ohm fuel level sender, and cover plate with both fuel & electrical connections, for around US $30-$50.
