Not at all! It fits snug up against the tank so no part of the fuel system hangs below the frame rail, therefore nothing to get knocked off if you hit a speed bump or have an off-road adventure. So, if you manage to knock it off, you'll have bigger concerns because you've already torn the frame rails out of your car! :)
Here's an excellent thread with pics on the PI Board about plumbing from the bottom of the tank, and other folks solutions with a quality high-flow banjo bolt, and or elbows.

And I'll a pic of my setup valve tonight.
Cheers!

With this Valve, it looks like it would stick out of the tank pretty far? Would you be afraid of hitting a Bump and knocking the valve off? Just Curious?

Hi Corey,
I'm not running EFI yet, but may someday in the future. Anyway, I put
a Groco 90-degree fuel valve on the bottom of my gas tank in place of
the drain plug. The 1/2" NPT thread on the Groco valve will thread
into the metric drain opening on the tank and seals with quality pipe
dope and a generic O-ring from O'reilly Auto Parts.
Benefits of the Groco valve are...
1. It doesn't restrict fuel flow like a Banjo fitting - it never ceases
to amaze me when I see high horsepower engines with 1/2" fuel lines
connected to a restrictive banjo fitting that likely has a 1/4" (or
less) internal diameter at best!
2. You can close the valve if you ever need to remove your
engine, change your fuel pump, or just replace the fuel line - no
futzing around with clamps or vice grips to try and stem the flow of
fuel from the tank if you ever need to perform one of these tasks.
AND, it serves as a great anti-theft device as well. If someone
manages to hotwire the car, they won't get more than a few yards down
the street before it'll run out of gas.
Here are a couple of links to the valve - I have the stainless version.
I imagine brass would be just fine too.

Anyway, if/when I add EFI to my car I will use the original pickup
location on top of the tank to plumb the return line.
Cheers!
