Any idea what sort of power levels the stock fuel pump can support , anywhere near the 450hp mark :?:

If not, what sort of fuel pump should I be after, and where can I get one from :?: :?:

btw, I am running 30lb injectors, pretty sure they'll be up to the task :!:

The stock fuel pump will have hemeriods trying to keep up with the 30lb/hr injectors and big revs. Aftermarket pumps that bolt straight up are available from Holley, BBK and Walbro in 155, 190 and 255lp/hr - and Ford Racing as a 190lt/hr.

My pump gave up at only 180rwkw, some have got upto 230-240rwkw out of theirs but as MrLandau said, the stock pump will have a lot of troubles keeping up with the 30lb injectors. I got myself a Walbro intank 255l/hr pump which is apparently good for 600hp.

I take it that a Walbro is what you are using to support your 330kW.
Is the fitting of this pump very tricky or pretty straight forward ?

Also, I found a place in SA that sells these for $195. Is this a good deal, or is there somewhere else that can out do that price (btw, I am in sydney although I guess postage from anywhere is not that expensive) ?

$195 is a pretty damn good price, just make sure it's rated near 255lb/h.. Fitting is relatively easy, just fiddly.

Yeah I have the Walbro GSS342 which is the highest spec intank pump they do, but any of the 255l/hr pumps (GSS340/341/342) are excellent units. Fitting is easy and will take about an hour. $195 is a good price, most outlets sell for $250-$400.

I've been meaning to upgrade mine for a while, as i'm running 24lb/hr with a reasonably high pressure reg. I'm sure going to something a wee bit bigger than 88L/hr will be worthwhile.

I think they can consider one of units on ebay as good as sold.

:idea: BTW, Candalini is a good example of what the penalty should be for belting a Falcon :lol: Fords bite back :twisted:

Would we all consider that a good price? :D

Would it be overkill for my ~200RWKW 6cyl?

Do you know what the difference is between the 340, 341 & 342 ?
Just curious as I cant find much info on these.
