Anyone know of a write up to use to swap fuel pumps? My fuel pump took a **** on me, needs replacing. Is there any write up I can use to do the job myself? I found this:
http://www.gonicd.com/intankinstall/...mpinstall.html
Is this pretty much the same for all brand fuel pumps?
Also does anyone have any info on this pump from Summit?

That's the write up I used when mine went. It's pretty straight forward, just make sure you are very careful when cutting the trap door so you don't end up cutting right through to the tank. Oh and go with the racetronix kit. It'll make things a LOT easier.

Not trying to cause trouble, but here's a couple:
Don't use fuel injection hose. It is not qualified as fuel submersible. If you choose rubber hose versus the flexhose, use SAE J30R10 hose, which is also available from ape. It is fully qualified fuel submersible, although there have been reports of Ethanol compatibility softening it (even with E10-15, which is what is used up here in Indiana). Also, using the rubber hose may lead to kinking during assembly, so be very careful to avoid this.
If you use the flexhose, the worm clamps will work just fine.
The link to ape is excellent, btw, since they carry all the things you should need for the install.
I strongly suggest using care when removing the retaining ring. Steel upon steel "...use a large flathead screwdriver and hammer and pound the retaining ring off..." can cause sparks. Sparks + fuel vapor = potential explosion. IIRC, I used a large pipe wrench or channel locks, which required no pounding (it's been a while).
Finally, if you care about the bucket integrity, or you tend to run your tank at low levels, you may wish to consider the Racetronix pump, which is a "plug n play" item.
All in all, it is a good writeup, but caution should always be taken.

To the OP - the Racetronix kit includes the wire kit from pump to alternator which makes a great difference in voltage to the pump over stock making the Racrtronix kit the ideal solution if you plan to mod or upgrade your system later. The Racetroxic kit will handle up to about 550 rwhp.
Not sure if the Summit kit will do that unless you install the Casper wiring kit along with the new Summit pump. But if you do that - the total difference in cost between both is very little making the Racetroxic kit the preferred choice.

For the small additional cost of the Racetronix kit over the Summit version I think the OP should go Racetronix instead.

Hmm some good info, I am going to check out a Racetronix kit now!
Also guys another question...do I need a fuel pump and fuel pump only? Or is there more to it?

Their site shows the kit and items included. Link below includes a pic of the kit but from Thunder Racing's site.

It appears that the kit is cheaper now too, compared to when I got one (about 4 years ago). My kit is for a 98. It currently supports an ATI D1SC Procharged 347 making 565 to the wheel on a Mustang dyno with 60 lb Mototron injectors. Fuel pressure is consistent 58 lbs.

The Walbro pump draws ~9 amps, vs. the stock pump's ~5 amps. The stock wiring is marginal for the current draw of the stock pump, and should really be upgraded for the increased current draw of the Walbro. The Racetronix harness is a very well designed and implemented piece.

I got a bit of two sense on this...I bought the fuel pump from summit a few months back and well lets just say it dont hook up like the stock one does! My stock pump had two fuel lines the man one the big hose and then the tiny one that hooked up to the pump and went to the sock. The new pump from summit has a whole where the little hose would hook up but no fitting to hook the hose up to....So my question would be is the lil hose needed or what is need to make this work??

Hey, here is an update, can anyone help me here?
I am looking at Racetronix pump from Thunder Racing. Here is the link, it is the 4th product down $150:
http://www.thunderracing.com/catalog...vid=3&pcid=165
I see right below that one, there is a kit that includes even more (wire harness) and it is $209.
If I pick up just the $150 unit, it says it is pretty much plug and play. I don't think I need the other unit as I do not plan on doing anymore motor work for the time being, also my stock unit held up for a while so I don't see why the other wouldent. Is the wireing harness THAT big of a deal? Thanks for any help, I am just still confused but would like to get this resolved soon. Thank you!
Also does anyone know of any same or similar pumps from different vendors for cheaper than that besides Summit?

It all comes down to the HP you want to support and your motor build (BSFC). ???
