a lot of guys use the SVT Focus pump, dont know who makes it though. Could also look into an 03 Cobra pump, but Im not sure if they worl with the GT tank.
 
The 2000 gt has a returnless fuel system, so you need a variable voltage fuel pump. The ones you listed will work, but not for very long since the constantly changing voltage will eventually wear them out. Your best options are limited to OEM pumps which are all very good.
SVT fucus pump.
Aviator pump.
Ford GT pump.
Cobra dual pumps and tank.

The first three are fairly inexpensive. Check out the "ford parts" forum on Modular Depot for the best prices.
 
I have the Aviator pump. The install was a lot easier than I imagined. I'm running an 8# pulley. Managed 362hp 393tq and never ran out of fuel or showed signs of it on the dyno a couple weeks ago. From my research the Aviator should be good up to 430hp with the factory basket.
 
I run the Focus pump, works great! If you're going to be going over 430-450rwhp, look into Cobra tank w/ pumps. The cobra tank is baffled and has dual pumps, should support 550hp or so - then when you upgrade the pumps/lines it can handle even more. :nice:

the 255 is fine but there are twon types of them. a standard and a high pressure/flow. get the higher pressure/flow one.
Is this where we all jump down your throat now, call you stupid and remind you that a '99-up GT's uses a returnless fuel system and your standard return 255lph pump won't properly?

Gotta watch that Karma, smart guy. ;)
 
does it works good with one focus pump?or put two of them? the vortech pump sais that is for specialy 99-2004 mustang maybe is made for that car because os the voltage diferences..
how many LPH is the focus pump?

what year the cobra comes with dual pump?

wich one of the 3 has more LPH?

2003-2004

The aviator probably it's 271lph. The problem is with the stock mustang gt tank and fuel bucket it is to restrictive to allow the pump to pump to its maximum. So after 425+ or so it starts starving for fuel. 2003-04 Cobras use baffles to keep the pumps submerged at all times. With a Boost a pump the cobra setup is good to over 600 hp. Even more with other changes like fuel rails etc.
 
focus pump and aviator pump are direct fits. there's a certain aviator pump though you're supposed to get I'm not sure the part number but someone knows on here. Also, I didn't drill any holes in my basket and I didn't show in drop in fuel on the dyno and I had 6 runs.

I had the aviator just make sure its for the 2004
 
The Focus pump is good to about 400-430 RWHP. Add a BAP and more.

Ford GT FPs are a good choice they flow way more than the Focus pumps, BUT, if you run one you need to run an additional FPDM to get that flow rate. If you run a single FPDM as stock, then they flow less than a Focus FP.

In a 2v car your best choice is 03 Cobra tank and pumps - the 2v tank's fuel can tends to get sucked dry.

As mentioned returnless FPs must be repalced with returnless style FPs. Walbro style FPs are Gyrator pumps, Ford FPs are turbine style pumps. With a gyrator FP you cannot control the flow by varying the voltage well enough to be acceptable. Walbro style FPs in a retunrless vehicle will result in drievability not being optimal and ealy pump failure. Keep in mind a Walbro style pump meant for a return syle fuel system, the pump is operating at only one (or sometimes two) speeds. The superchager manufacturers whoo include Walbro FPs in their kits do so for one reason - they are cheap and they need to keep the kit costs low.

i have an aviator pump in my stock GT basket and dynoed at 433 whp, and actually my tuner had to lean it way out because the pump worked that well. i would say and he told my the aviator pump is good to 475 or so rwhp, now with a BAP it would be good to 550.

Its not that the aviator is not a good pump. It's that the gt fuel bucket that the pump sits in can be sucked dry by the pump at higher hp levels. I had the aviator fuel pump.
