In tank fuel pump options

Hi all,
I've had my beetle running on subaru for a couple years now and although I have an extremely robust fuel system I'm considering going to an in-tank style pump.

Right now I have a 100gph Carter internally regulated at 5psi feeding a 1.5L surge tank, and a Walrbo 255lph pulls off the bottom of the surge tank. The surge tank has a small 3/16" bleed that tees into the fuel return line so the tank isn't under pressure.

My complaints about my current setup are that the surge tank and both pumps are within 8 inches of the front apron of the car. So a front end collision would result in fuel shooting everywhere. Also, the pumps are loud, the carter hums and the walbro whines. Also, an intake pump would drastically reduce the number of fittings and feet of fuel line, and also help keep the pump cool so it lasts.

I'd like to keep the factory tank so I'm looking at something like this:

Do you think the supplied baffle would be sufficient for hard driving? They suggest to mount the pump to one side of the tank (left or right) with the baffle facing the center, that way turning one direction the sloshing is in your favour and turning the other the sump/baffle is doing the job.

Thoughts? Anyone do it a different way?

Mike
