440cc/min.

You don't have to upgrade your fuel pressure reg., some do and some don't. On my fwd, I left in the stock st-165 fuel reg. Works fine.

What you can do about a fuel filter, find a nice 10-micron one that has an -AN inlet, and then get the two -AN to stock 3/8th fuel line adapter, just screw it all together, I am willing to do this for you and just send it to you, all you'd have to do is screw in the inlet and oulet where the stock one was. The stock fuel setup should be okay for 300hp, I'd go for 6-AN lines if you want up to 600hp worth of fuel, but the Walbro 255 won't support much over 500hp so far, as I have seen. Feel free to ask any other questions as well.
