Default Square body S10 fuel pump

I haven't posted anything for quite a while. Could use some constructive input.
91 S10
Daily driver
Modded LQ4
4L60E
3.:42 rear gear
Stock 20 gallon tank
Holley Terminator X Max

The fuel pump decided it was done playing, took its ball and went home.
I need to make a decision for a replacement using OE sending unit.
I used an Aeromotive Stealth 340 in the GTO.
What is the current conventional wisdom these days?

IMO, on something like that, unless you have plans on changing the setup dramatically, I'd just shove a 340 in it.

A common walbro 190/255 is plenty for that combo. 340's have a hit n miss track record, but if you luck out on a good one then it'll be fine

Be sure to buy some real submersible hose and proper EFI clamps. Can't tell you how many good suppliers still put the improper hose and simple worm clamps with good pumps

i agree walbro 255 would do it, be careful theres alota fake parts out now including walbro pumps/spark plugs/etc..... so get one from a known good source not amazon..... side note have you thought about making a nice air box on that drv side to get that air filter off the rad.
