Fuel pump choices?

Scamp,
Trust me the Carter is THE best for what you want. Absolute nonsense from Rat Bastid.
Firstly, all the gph numbers quoted from pump mfrs are free flow, so they ALL produce a little less when you add lines, filter, regulator, etc.
Secondly, search the web & see how many failures of the above mentioned electric pumps you can find. I know of one & am not convinced it was the pump's fault, as details were vague; if you run the pump without fuel long enough, of course it will fail. I know of a 4594 that was on a daily driver for 19 yrs [ yes, 19!!!! ]. It was replaced; not because it failed, because the owner thought it had earned it's 'retirement'. I have the 4600 on my car, been on 17 yrs, driven weekly. A previous car I owned had the 4594, had been on over 10 yrs when I sold it. It had, for awhile, been driven daily for work.
Thirdly, you can buy a pump like the Edel, looks nice with the billet plate/housing, but it will not anything better or more reliably than the Carter, but it WILL lighten your wallet.
