pumps do not put out pressure or a specific pressure, they flow fuel.
regulators set the pressure.
there are many stock application pumps that will do the job.
for a stock-ish engine you do not need a high flow pump like 255lph
for a 2bbl tb efi setup a stock type pump for something like a camaro/mustang/vortec truck would be more than adequate.
I prefer to use stock type parts vs. aftermarket, readily available @ parts stores, lifetime warranty, etc. if needed.
Walbro and similar are fine, but more expensive, and generally no warranty.
