swift13 Posted April 26, 2010 Report Share Posted April 26, 2010 my fuel pump needs be replacing today on the gtp. my question is what is a good one to buy? is there a performance one that can still be used on stock settings? (incase later i decide to do stuff) 98 gp gtp Quote Link to comment Share on other sites More sharing options...
Euro Posted April 26, 2010 Report Share Posted April 26, 2010 Honestly I think the stock pump will do just fine, unless you want to do some 350whp+ stuff. I've heard from a few people that the Walbro's and stuff are a waste unless you're going big. Quote Link to comment Share on other sites More sharing options...

Euro Posted April 28, 2010 Report Share Posted April 28, 2010 Then a GTP pump will be your best bet Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted April 28, 2010 Report Share Posted April 28, 2010 On the other hand, it's not like the price difference is huge. The Walbro 255lph high pressure pumps are usually less than $100 shipped. The OEM pump for my car at least was $80+tax from O'Reillys, so it was just a little bit more for the Walbro, and having a pump with higher flow capacity doesn't hurt. Not to mention the Walbro is significantly quieter than the original fuel pump, at least in my case. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted April 29, 2010 Report Share Posted April 29, 2010 Is that a modular pump on the 98 gtp? can these be replaced seperate of the module? Quote Link to comment Share on other sites More sharing options...
RareGMFan Posted April 29, 2010 Report Share Posted April 29, 2010 On the other hand, it's not like the price difference is huge. The Walbro 255lph high pressure pumps are usually less than $100 shipped. The OEM pump for my car at least was $80+tax from O'Reillys Gen II GTP fuel pumps cost a wee bit more than that. New from GM, it lists for about $480. Even lower end after market stores like Auto Zone and Advanced Auto have them for $250 - $300. I got mine from NAPA at employee price (which I believe is cost). Granted, it actually has Delphi sensors, so I believe it's an actual GM pump under their house brand name, it STILL cost me $150, which is why a lot of guys just swap to a Walbro when the time comes to replace the pump. http://www.autozone.com/autozone/catalog/parts/partsShelf.jsp?categoryDisplayName=Fuel+Delivery&fromType=parts&fromString=search&parentId=49-0¤tPage=1&filterByKeyWord=+%09E3519M&isSearchByPartNumber=true&navValue=14900078&categoryNValue=14999999&fromWhere=&itemId=78-0&displayName=Fuel+Pump&searchText=+%09E3519M However, I think there is a fitment issue with the Walbros in the Gen II GTPs where it doesn't reach far enough down to suck up the gas, so you run out of fuel sooner than you expect/the fuel gauge indicates. I think there's also some other customizations to make it fit in the tank properly, too. I know there's a fix for all this stuff, but my point is it's not just a simple plug n' play.

GnatGoSplat Posted April 29, 2010 Report Share Posted April 29, 2010 Yeah, my Silverado uses those stinking fuel pump modules too. For me, the cost alone would be motivation enough to find a way to custom fit a Walbro. At least the gen 2 pumps can be pulled out without dropping the tank so if there were little issues to be worked out, it wouldn't be quite the headache that it is on the gen 1s.

swift13 Posted April 30, 2010 Author Report Share Posted April 30, 2010 it has to be a gtp pump right it cant be for a gt or se? Quote Link to comment Share on other sites More sharing options...
Addicted to eaton Posted May 1, 2010 Report Share Posted May 1, 2010 Yes, Needs to be a GTP pump, And it can not be a 1997 pump. 98-03 Quote Link to comment Share on other sites More sharing options...
RareGMFan Posted May 1, 2010 Report Share Posted May 1, 2010 Actually, I think it's one part # for '97, then another for '98 - '00, and yet another for '01 - '03. Quote Link to comment Share on other sites More sharing options...
