This post is just to document that I've finally officially started. I'm not going to give a blow by blow because this may take me a little while since I'm not as great a mechanic as most of you guys are. Instead, when I'm done I'll make another thread or continue this one if anyone is interested. But for today, the tank was easy. I had to do a little wrestling with the rear factory lines but I got them out intact without too much trouble. I have the front lines mostly loose but I'm not sure if I can get those out in one piece, I may have to cut one or both of them.

I'm just using the Tanks inc door. I did a search and didn't find anything else.

I use the tanks access doors. I've never really researched others because I just put one in the cart when I'm ordering tanks inc stuff so I'm not sure what else may or may not be out there.

I will say I always get the biggest one tanks offers. And I wish it was even bigger.

Reason being is it's nice if you can build the setup in such a way that if you ever need to remove the pump you can unhook the lines and everything else from the access door and pull it all out, and never need to crawl under the car for anything. I always try to think I'm in a road side repair situation when I build this stuff so I can make the repair as easy as possible.

Ive.had to pull a pump out after the fact and have to say the access door is sweet. Doesn't even matter if it's a full tank of gas. Pull it out and swap it is a very easy 30 minute ordeal.

And I used to be the guy that hates cutting floors since I source all my cars from the rust free region of the country but in this case I make an exception. I can easily weld it back up and refinish it like it was never there if I desired.

I've looked at the Quarter-Max ones before, they have several options:

https://quartermax.com/shop-all-depa...doors-latches/

I did find others that were intended to be used on campers/trailers, but most didn't have a seal.

I'm sure there's more out there, but I gave up the search after deciding I didn't want to cut a hole in the trunk floor.

What is your process for locating the cut out? My plan was to make a template out of cardboard and lay it in the trunk. I'm just not sure how close I can get it to where the tank will actually sit.. If I didn't have the transverse muffler, I could mock up the tank then drill a small locating hole to mark the rear of the tank. but I won't have access for that. I guess I could use the template to get a general location then use a hole saw to get an exact location.

I did get the largest one which seems adequate, but tight. I guess you could get two smaller ones and put them next to each other.

Edit: I found this one: https://allstarperformance.com/acces...14in-all18542/

I typically pre fit the tank and mark it from the bottom, drill some pilot holes and use that to make a template from the top.

Thank you and everyone else for the information. I'm at this point and this is perfect timing for me to install a door.
