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

Thanks
one of many that will work. I get the one for the 87 Buick GrandNational from Racetronix.com
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?
Racetronix - G7 Fuel Pump Kit - Kit Configuration Page=
Comes with the GSS340m pump
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.
Ahhh crap. I didnt know that was a problem when buyin these.Quote:

sorry man, i dont get on too much anymore. ive been trying to finiah up the truck plus build my 6.2. ive been helping a few buddies w LT installs, Stalls, next is a Roush TVS1900 on an 09 5.3 an spec'ed SC cam. then gears in the CC. plus working 5-7 days a week is a killer.
if your interested pm your info. i cant ship it until monday unless my buddy does it for me.
At the rate you were goin, I thought u were gonna have the WT done by now. I was really excited to see it done. Now it looks like I may have mine done before you since I am starting my swap this weekend. I'll have all day sat and sun then during the week i should have some time to finish it up since it's spring break and I don't have school. Problem is, my cam is not here yet, tune is not here yet, converter is not here yet, and a few other random parts aren't here yet but should be in by the middle of next week.
Yes but Jack or any other Walbro dealers offer any kind of warranty.Quote:

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!
Thats the first bad thing Ive heard about Walbro pumps.Quote:
