What's this census on one of these gems? Is the walbro-knock off I keep hearing about? Seems legit.

Perhaps not this model, but this brand. I have it saved on my cell phone / ebay app, but cannot pull up the same on a desk top computer.

Re: Is the walbro-knock off I keep hearing about?

Most are junk & fail in a short period of time.

Also a 340lph is overkill for applications under 550rwhp & they draw a ton of current that can overload the factory wiring/connectors in the fuel module.

The connector in a 3rd gen tank is rated for 13A & most 340's draw 17A or more.
Fuel & melted wiring are not a good combination.

For as much grief you go through to swap a pump in one of these cars, I would only use a proven quality pump.

Thanks Lonnie. I hear that! I looked up at Rock Auto and seems like I could get a GMC Syclone/Typhoon Fuel pump for about the same $30.00. Plus its upgrade and the same plugs/wires as the OEM F body.

I'll pass on the ebay gig.

Hi there.
Is it possible to get the product number at Rockauto and also what regulator i should use on my ls3 swap in my Iroc z28.
The regulator should be possible to adjust from the tuning program.
Thanks Hans
