What's needed to drop a walbro 450 into the stock fuel bucket?
I'd like to upgrade my stock pump with a walbro 450 to work in combination with the magnafuel 4303. Can I just drop the walbro 450 into the stock bucket with a little cutting and the racetronix fuel pump harness. Any wiring to be aware of that isn't plug and play? I'd love to see some pics or hear some experiences. Also, are people using a particular source for the pumps?

This looks like some good info:
We do not include a filter sock or wiring with our F90000267 pump b/c not everybody requires the same hardware. We have adjusted our price to reflect this. Customers can use our FPWK-017W harness kit to install the F90000267 pump but they will have to change one end of the in-tank harness (which is Teflon 14 Ga.) which has a standard Walbro-style GSS connector to the Delphi RCS-057 listed in our web store. We recommend the FFS-250G filter sock, FFT-150 fuel tube, OCLMP12.3 and OCLMP13.3 clamps for installation.
A few IMPORTANT notes worth mentioning here:
1. The factory return system / regulator can NOT handle the fuel volume of the F90000267 and F90000262 pumps so a rail-mounted regulator with -6 Teflon return line will be required. Running the system without this will cause a major pressure rise and premature pump failure.
2. This F90000267 and F90000262 pumps will not support the factory jet-pump system incorporated into the fuel module so holes will have to be made in the module. Disabling this system means that the bucket will not fill above tank level and b/c there is no baffling in the tank an adequate level of fuel will be require to prevent the pump from running dry esp under agressive driving which causes the fuel to slosh around in the tank.

I just put one in my car. Unfortunately I didn't take any pictures. As long as you don't mind putting holes in your stock can it's not a problem. The pre filter is different but it's not an issue. I drilled a lot of 1in holes in the can and removed the majority of the bottom.

Also the only wiring involved is I cut the connector off the 450 and soldered it to the leads for the factory in tank connector. This is where I bought mine. http://m.ebay.com/itm/170945680470?nav=SEARCH

The 450 is designed for e85 and should support ~700hp. The stock pump with a boost a pump might support 550-600hp on e85 if the pump lived. E85 killed my brand new z06 pump in a few hundred miles. My external magnafuel does most of the work, so I just want an e85 friendly pump that will drop in and also flowa decent amount.

That link didn't show up on my phone, sounds like what you cut and soldered I could use that racetronix quick connect for. Glad to hear it drops in pretty easy, any fuel pickup issues with the modified bucket?

Couldn't have been just e85 that caused the problem. Lots of people use e85 in z06 cars with no issues.
Hell my 120k mile z06 pump takes e85 just fine..
If you got a magna fuel I would just use a stock pump. Not worth the possible captivating trouble to deal with holes in a factory bucket. Especially in an e85 street car. Because I would think you run around empty or close to it on a regular basis.

The wiring I was referring to is the actual power and ground wires in the tank. The 450 will come with a connector already on it that will have to be cut and soldered to the factory in tank wiring. I also use a racetronix harness for the exterior wiring. I use the 450 in tank as a primary pump and a 4303 y'd into the same feed off a hobbs. Also I've had no issues, just be conscientious of the fuel level to prevent any over heating/ cavitation of the pump.

racetronix is kind of hard to get a response from.... I'm trying to understand if I need the harness they listed, or if that's for an older f-body or something...
I'm picturing the C6 harness below running the direct wire from the alternator to the top fuel pump assembly plug outside the tank.
C56 Fuel Pump Wiring Harness - FPWH-008 - $59.99
Then I'd leave the connector on the Walbro pump so it would attach to this new one:
Fuel Pump - 430L/Hr, E85 Turbine HP - F90000267 - $139.99
Connector Set, Fuel Pump / Hobbs Switch - RCS-057 - $2.50
Then I'll cut the wires off my existing fuel pump and that new connector will attach there inside the bucket and the original plug will still connect to the top of the internal fuel assembly?:
Does that seem right? I like the idea of using that connector vs. soldering wires together in the pump assembly.

I have one in my car, I don't think there is a lot involved in the install as mentioned earlier. I never took pictures even though I saw one being done just few weeks ago on my buddy's vette. I will next time.
and yes some stock pumps works fine and some don't. I went through 3 factory pumps. I think one was within few days!!! I forgot how long exactly but I posted about it so you should be able to find it. It would be stupid to go through all the trouble of doing a pump swap only to put a stock one back in it (I did it three times, and wish I just did the E85 pump the first time, what awaste of time and money!!)

After doing some research and talking with the guys over at Advanced Modern Performance, the stock pump will fit but again, has to be modified and I'm not sure you can get away without soldoering. I'm personally about to do a full fuel system with a triple walbro 255 inline along with new lines/hoses rated for E85 so I dont have any issues with E85. I just bought ID2000 injectors which is more than enough to support the fuel I need, maybe overkill but you never know what I might do in the future so better to do it right the first time than to go back and redo it. Alot more cost efficient IMHO...
Now one thing Iam worried about is once my car is tuned for E85 which is very available here in Texas everywhere, but once the temps drop and they go as low as E70 (Some people say that Texas stays E85 year round and others say they have seen it go as low as E70) how is that going to affect the tune? especially if its tuned for E85....
