Wallbro GSS342
Hey guys, I recently purchased a couple of parts from an org member including a Wallbro GSS342. I'm currently in the process of building the 3.0L, with compression ratio at 9:1, I'll have the heads port & polish with better valves & spring, new cams, injectors, headers, a Vortech V2 & what ever is required to properly tune this beast. So does this Wallbro is the best choice for this set-up.
Thanks & have a good one.

Walbro is the most commonly used high flow fuel pump, but they have a little bit of a reputatoin for premature failure. They are a good pump and are relatively inexpensive. If you wanted something better you could go with the Bosch inline pump

With the kind of money I'll be puttin in this project, I'd rather not have to replace the fuel pump once everything is done. Do you know of any online shop that I can order ?
Thanks I really appreciate your input.

The Wizard is spot on the money: DO NOT get below 1/8 tank at all to be safest. These pumps are high velocity spinners and at that rate, if it's sipping for gasoline along with air pockets, it'll decapitate the pump prematurely. GSS342 is a direct fit, and I doubt hardwiring a direct power source is the remedy. I'm leaning towards air pockets in the pumps doing the magic at that velocity.

The reason some recommend to hardwire the pump is because some 4th gen models have the fuel pump control module, this keeps the pump running under a lower voltage than 12v, its rpm and load dependent i believe. so if the engine has certain load or at certain rpm the control module will raise the voltage of the pump. If you disconnect the drop resistor that connects to this module and ground the pump directly to the chassis (drop resistor provides a controlled ground to the pump which changes the voltage) this will allow for the pump to run at 12v or w/e the car's voltage is when on, 13something.
I am pretty sure this control module crap was only in 97's
I say you go with walbro.

EDIT: The difference is in their inlet and outlet styles:
