    I just recently did a fuel pump replacement in my SVT Contour through a hole in the floor. Ford provided a small access hole, but it's not large enough to remove the pump assembly from the tank, so you have to cut and patch.

    There must be some sort of perverse natural law that causes your fuel pump to fail completely tits-up dead right after the tank is filled, as this is what happened to me.

    I'd have no problem doing a through-the-floor pump replacement in my SHO. Just seal it back up well and it's not going to be a problem.

    I replaced a fuel pump from a tank had been filled to the brim 15 miles prior. Personally, I would consider this safer, as a spark on a full tank results in a small fire directly above the hole; a spark in an empty tank results in KABLOOEY! Remember, it's not the liquid that catches fire, it's the vapor...

    Don't taunt your Fuel Pump... I expect it will grab your attention soon for thinking such things...

    I just replaced a fuel pump in a 94 ATX using this method. It took me all of an hour and a half to complete the entire process. Hell, the hardest part of the whole swap was getting the fuel return hard line separated from the old fuel pump.

    I did the same thing. It is pretty easy. I will not say how I cut the hole - should blown up. But this process IF FOLLOWED is a great easy one man job.

    I wanted to add a word of caution here. Those Dremel wheels ARE big enough to reach the fuel lines in some cases. I think the problem is that every car is different - some have more clearance between the lines and floor than others do. Mine were just a couple millimeters below the floor, and if Hamal hadn't been paying close attention when he made the cut, he could have easily hit one or both of the lines. When I checked them afterward, I could feel a few little nicks, probably from when the wheel grabbed. Bottom line - be careful and pay close attention to what you're doing.


    I also had to quote Mr. Vapah Lock here for the lulz:

    We cut this opening on our crapcan racer and while five of us stood around debating the best way to make a replacement door for the hole, Russ walked over to the parts car and cut a piece out of the floor approximately 1" bigger on each side.

    It fits directly over the hole and is secured by a few self tapping screws. If you have a parts car and this mod, I highly recommend this.

    I just did this a different way and thought I'd share. I drew it out just like you said, but rather than drilling I got a sharp chisel and a hammer and just used that for all the cutting. It took like 5 minutes, and was a lot easier I think

    Opinions please...
    I have been using this rockwell multi tool things that vibrates like all get out and cuts metal, I chopped up an old rusty grill in about an hour into pretty small pieces. .I'm thinking this would be a great tool to do the cutting..there's no sparks you can see the depth you are cutting by how much of the "blade" is above and the shape of it actually. It's the kind of think some people use for sanding stuff too. It just vibrates so hard and fast that it'll cut steel with the correct blade on it..

    Oh yeah, and there's this sonic-shear..I haven't used it but I think it'll cut steel like tin snips.. Do people think this'd be a good tool for the job???
    I may be replacing Babe's pump..I'll know tomorrow.
    Thx,
    T
