Did a quick project today that I thought I would share. This is nothing new but it's been something I've been wanting to do for a while. The thought of dropping my 31 gallon gas tank in the middle of nowhere, in the dirt, on my back to change a fuel pump was not appealing. I know a lot of newer vehicles have "trap doors" from the factory but for us with older rigs or modernized ones like me this may be helpful. I found this idea from another forum after searching the net, it's real simple and cheap.
I bought a plumbing inspection door from Home Depot for $35, it's made of nice heavy steel and comes in several different sizes, this one is a 12"x12"

Next I made a semi educated guess where the center for the sending unit would be and drilled a hole, then I used a flashlight to actually find the center and drilled another hole.

Once it was centered I traced out the opening and cut it out.

Then a quick test fit.
