Good points all, but I think the bottom line is whether it works in this specific case. I have fallen victim to buying cheap Chinese parts that turned out to be worthless. I have also bought non-OEM/OE parts that were a fraction of the cost that worked just as good as the expensive stuff. Sometimes the cheap option works and sometimes it doesn't, and the pricey parts are worth the extra money.
So, let us know how well your project works. Certainly is great info if it does work well, but no shame in trying and failing if it turns out not to work so well. That's what these forums are for - share the knowledge.

Well, this one's a little more than $30, but it's also billed as a direct replacement http://www.rockauto.com/en/moreinfo....357185&jsn=343 Sure beats $458 at Pellican...

You have to add it to your cart to see the price - it's $152...

I went out today for a fairly spirited drive on the interstate, with high rpms and heavy throttle (all well within limits: no reason to abuse the machine just to try to prove something) for a period of time just to see if I could create a fuel starvation at high flow issue. Happy to report all is well so far. Fuel flow was a concern of mine, but is not an issue-yet. Much shorter crank times to get it started too.
Ahsai in #13 has the PN.

The limiting factor may be the specification of the injectors not the flow rate of the 'hack' fuel pump ??
If the flow rate is good enough for a 996 ,it should be O.K. for the 986 also.
Good find and even better test results.Thanks for sharing.

After only a superficial look at your pics My only concern is the use of gear type hose clamps. I know you can buy the proper crimp on style clamps from an Evinrude dealer . They can be crimped with end cutting pliers.

I'm not necessarily sure thats the best way to do this.

Lots of cars run the best right before they lunch a piston due to a lean a/f condition.

You can measure the flow rate by disconnecting the fuel line and running it into a buck for a specified time period. Use whatever calculations to get to your lbs/hr or Lph, and compare to stock.

This could be a good idea.

However one could argue that for a primarily street daily driven vehicle, the injectors aren't going to be anywhere near their max duty cycle most of the time so it's rarely going to utilize the full flow. Otoh, if the fuel delivery rates vary enough where you do end up racing or getting on the throttle to redline, you may not be producing full power.

Now all this could be negligible in a real situation but this is RL so there's gonna always be the obsessive over analysis cautious doom and gloom thought process here.

good suggestion, and I'll do that. As for the concern re the worm gear clamps, I safety wired them in place such that they can't back off, or if they do fail somehow, they'll remain in place, rather than rattling around in the fuel tank, like the gas can filler shutoff valve that I found in there.

It is exactly the one I put in last week. Fired right up and the fit was OEMish enough to me at fraction of cost.
Reason I replaced the OEM Valeo one was that some sort of check valve inside the old one was not doing it's job properly draining fuel back into tank once the pump was not turning causing loooonng hot restarts.

Oh, and this will should help you with your flow rate test (per Porsche manual); 850cm3 per 30 seconds

Good to know. Love this site because it's such a wealth of shared knowledge. I learn something new everyday it seems. The Porsche tax is very apparently a thing, based on this.
