Which Walbro for OBS swap?

[flattopwill]

Is the Walbro GSS340 the right pump for a direct swap in a '91 silverado tank?

Maybe racetronix appends the M in their numbering system or they just keep using it because people want to see the M on the PN. At least with Racetronix you're guaranteed to get a genuine Walbro pump and not a Chinese knock off.

... a Chinese knock off.

Ahhh crap. I didnt know that was a problem when buyin these.

Yes but Jack or any other Walbro dealers offer any kind of warranty.

Years ago when Walbro's were failing left and right,Jack was quick to tell people they had installed it wrong.

I bought a pump from Jack that was bad out of the box and I was told "sorry,no warranty" after I got the "you installed it wrong" BS.

Please dont take this as a stab at Jack@Racetronix.His wiring upgrades are second to none and IMO,he is the best in the business when it comes to innovative wiring solutions.He just sells crappy fuel pumps with no warranty.

I went with the higher flowing Denso fuel pump that was original equipment on the JDM and USDM 93-97 Supra twin turbo's and havent looked back.I actually had to turn the fuel pressure down as it was up 5psi at idle vs the Walbro!!

You guys can waste your money on a new Walbro every other year,lets hope you get lucky and it fails just cruising around,not at WOT torching pistons and head gaskets.Totally not worth blowing up for the few xtra $$$ the Denso costs vs the Walbro.

The Denso pump is also a much better solution than the old Bosch pumps people use.The Denso has been proven to flow more than any Bosch or Walbro pump.I want to say the Denso is rated at 285lph vs Walbro 255.I have also seen flow charts of the Denso at over 300lph when the intank wiring was upgraded to 12 gauge.

Go Denso and never worry about intank fuel problems again,EVER!

Im takin your advice on the Racetronix kit except minus the hotwire kit. I think I can manage without it.

[flattopwill]

Great. Thanks. I just couldnt figure out which Walbro will go in without any modifications or trouble.
I noticed the pump used in the Racetronix kit is labeled "GSS340M" but google says that pump has been discontinued?

[keniff]

120 shipped cheaper than racetronix 198 shipped
BNIB its the same one in my LSx swap an Redheartbeat is telling you to buy.
