some body please help
some body's got to know i've been searching my *** of all i seem to find is 03 and under can't find any 2004 people installing pumps

Walbro GSS340 intank. Do a search there is a bunch of info on it. I just installed one. 03 and 04 installs are pretty mcuh the same, cept you have to move the regulator of the way before you can pull the pump out of the module or somthing. Try to find a gss340 install kit, comes will everything you need (plastic hose, fuel pump sleeve, filter, ect) I was able to get it for 120 bux. Install took me about 2 hours once i figured everything out since the directions was for an 04 (i used magnacharger's directions)

where did you get your intank set up nate.

I got it from magnacharger, but they won't sell it anymore.
STS has the same kit, but they charge 170 for it.
I'm sure there has to be another place out there that sells the same kit.

I got the inline Walbro pump. The kit is from Magnacharger and I replaced the filter all in one quick swoop- couldn't be easier. This pump should support well over 500rwhp and it comes with all OE fittings and proper U-bend and pre-wired harness... i think that you'd max those injectors before you max this pump out anyways, so they are a good match.

I have just heard some slower starting issues and just the idea that you can't ever run your tank near 1/4 since you have to cut out the bottom of the stock fuel sump and rig up some wires inside the tank to get the walbro In-tank to work... did i mention removing the bed or pulling the gas tank to get at the module?... just something to think about, cuz one pump isn't superior to the other in my opinion(they are both walbro 255 lph pumps)

btw, some people don't like the fact that you can hear the in-line pumps and they are too loud, but the pump really isn't loud at all and you would never be able to hear it over the exhaust... plus with forced induction, it gives me a little piece of mind that the pump is working everytime I prime the engine before startup.

the only problem i see with in line pump is that my regulator is in the tank so how would you regulate a inline pump??

You could not do an inline on an 04
