Default Trap Door

What did you guys use to cut a trap door for a fuel pump install? I don't want to risk using a cutoff wheel. I'm afraid I might blow myself up lol.

Thanks for the reply...thats what I wanted to use ideally, but I dont have an air compressor. I took the risk and used a dremmel wheel. It worked fine, and I'm alive to tell about it....no explosions. I stuffed a wet rag over the fuel lines, to catch all the sparks I was making.

I used a dremel. It'll work fine just becarful to keep it as close to the surface as possible. Also, use some RTV to seal up your trap door.

Also remember 98's are different and you cut in a different location than 99+ F-bodies. On the 98, you cut the same size hole, just right at the front-most portion (about an inch back from the curve).

Great catch. I completly forgot to mention that. Hopefully nobody with a 98 started cutting yet.

So the 98's are the same just 1 inch back from the front of the hump? How big was the acutal whole b/c you need some room to screw or rivet the plate back on right?

Yes the 98s are pretty much opposite of the 99+. I believe mine was about 6x8". Basicly I cut between the two indented rails leaving a 1/2" lip to screw to. I guesed on the length and pretty much nailed it first time.

For a 98: Go to- http://www.worldisround.com/articles/12533/index.html
Just change the top and side measurements to 1" and leave the bottom one the same. That made a perfect hole for my 98.
