I haven't seen anyone in here talking about this product as yet, but for some of our higher HP builds that are coming through lately requiring much more fuel, there's a bigger and better answer if you want to keep things relatively stock looking.

Lethal performance is supplying these Billet - triple pump assembly's now with three Ford GT pumps:



Here's a link for those whom want to get more information:

Fore Precision 05-09 GT/GT500 Triple Pump Fuel Hat [FPW-S197TRIPLEHAT] - $420.00

[07 Grabber GT]

Uh ... just for clarity, what are you calling "Higher HP Builds"? Triple Ford GT Pumps would be about 1,500 HP in my books ... anyone seen one of those?

Wow ... talk about fuel delivery.

[onederful100]

this must be a step up from the GT 500 FP. so must be for applications upwards of 800hp.

Anyone know why you need 2 fuel pump drivers for running more than one pump? Woudn't it be just as effective to run both pumps off one signal so they both run a little slower at cruise and supply both pumps' worth of fuel when needed...at a matched rate? And they only need 2 pump drivers for 3 pumps?? One for the cruise pump and one to drive the 2 high-load pumps? Dunno.

One driver will not carry enough current to run two pumps. You need more than one driver for more than one pump period. As of yet, know one knows how much this setup will support, but it is a step up for those that are maxxing out twin GT or GT500 pumps. Also, for running three pumps they have a driver setup that you can buy that comes with 3 drivers built into one very nicely machined billet piece. You can see it on the website that emay posted a link to.

A smarter efficiency thinker would run these at a far less power rating, of course HP versus required fuel is not a dead on figure as we all know. That said, I would put money into this layout at about the 600-650 range and hardly work the pumps in terms of duty cycle. Not to mention have a safety net in the event one dumps at that power level.

Same reason we run 3 generators each capable of powering a small town in our aircraft...they last a lot longer because each one is working at 33% of the demand, rather than constantly trying to push 80-100% rated output...and yeah, you lose one or two, who cares? Your other ones can pull the slack and still not be near over-tasked.

But that's an option, right? It will run off 2 stock drivers if you don't get that driver? Maybe I read the description wrong on the website, but I could swear that's what it said.

I mean its nice and all ... but redundancy is not necessarily the appropriate thing in car applications. The consequences of a single pump failure in a car is not the samething as in an aircraft ... and if you had to pay the price for a car built to the standards of aviation we wouldn't be able to afford a Mustang.

Anybody seen a factory electric pump fail before ... I bet you heard of them rather then seen them ... statisically speaking its right next to "almost never". You'll have seen a dirty filter burn up a pump long before you would ever a witness a single pump failing in a properly maintained fuel system.

Anywho ... nice set-up if plan on going quicker then 8 seconds down the 1/4.

I've seen 3 factory Ford pumps on S197's (2 - 2005's and and 07) in complete failure, not gummed up, no filter issues, completely fried. It's more common than you think. I seen the FPDM's take a shit as well on a couple others.

For a supercharged car, redundancy is extremely nice, no chance of destroying a motor because of a faulty pump. A daily driver N/A I see your point.

+1 alittle extra security never hurt

Car has GT500 dual pumps (had pump problems twice... one electrical, one pump mechanical failure), 2 single Kenne Bell baps, 60 lb injectors, very large lines and rails, and my tuner (with very conservative timing), is very reluctant to go up on the boost for leaning out (at 20lbs right now). We're looking closely at the triple hat and 83 lb injectors, but not sufficiently convinced that is the way to go. We've tried larger injectors before and that didn't work. With the intense summer heat/humidity, it's our relative racing off-season now until October, so we're not rushing.

Turbo, motor, transmission all 1000+ hp capable...it's the fuel delivery that's the weak link.

[Trick Tuners]

The triple pump setup is for huge hp. No point unless you are 650+ and planning for 1000+ in the future. You can't run 2 gt pumps off of 1 fpdm, it will go into thermal shutdown. The twin pump setup is better for most people unless you BIG plans. I figure if you are going that big a return style system is a better option. You can tune those pumps for high hp, but its a lot of work for a competent tuner, but can be done. An amateur tuner will F' it up for sure. Return style is great because there is no tuning and its purely mechanical so there is NO delay.

Actually i'm currently running 2 GT40 Pumps off the single stock FPDM. Agreed though, a second FPDM is a better way to go. The question is, how do I add it at this point. Wondering if this would work.

Splice wires going to pins 1,2,5,6 on FPDM1 to respective pins on FPDM2
and run wires from pins 3,4 on FPDM to 2nd pump.
Haven't gotten a look at the gt500 wire harness, but i'm assuming it isn't that hard to add the second FPDM.
