It’s a 1970 with the tank as part of the floor. I’ve talked to more people and Hotrod shops then anyone should ever have to do. My opinion is fuel cell or modifying a 70 Mustang tank or cutting my trunk. I’m going with a newer efi carb and running the fuel cell with everything new sounds the best option for me. I’ve even had my original tank looked at and was turned away from the radiator shop with them telling me to use a fuel cell. I had a restoration shop for 7 years and was the main fabrication technician
I understand the 70 tank situation. my comment was for...73rustymav I'm thinking he has a 73. you have a pic of your tank?
The radiator shop that I went to said that there’s too much rust inside the tank to recondition it. He turned me to a flat bottom fuel cell but I’m actually waiting because I want to get all the plumbing done first. I’m still in the process of undercoating the rear of the car. I might have to draw something up and have it fabricated. For the filler neck tube. I’ve been having problems with the vent system. I’m thinking about running a purge canister but my fuel knowledge is from the 90’s Purge flow valve, sensor, and canister. Pulls vacuum though the valve and sensor and the fuel vent hooks to the canister. I appreciate your feedback and It dose help troubleshoot the issues I’m coming across Hope your day is treating you good I’m dealing with the big fire up in Redding ca so it’s too smoky outside to work on the car
Hey 71gold yhe 73 was wreaked and became parts for my early 70 but you are right anout the 71 and up being easyrer to get tanks for
Unfortunately it has a big dent and the inside is rusted out. The vent system was broken way back in 2002 when the car was my daily driver. I had hopes of using the stock tank but after I took it in for repairs I was told it was to badly rusted on the inside
This is what I’m going to do with my maverick. Except for the 302 labels will be grabber labels Bigger tires in the rear and different rims I also have a early black grill with out the extra parking lights. The parking lighting on my 70 are below the bumper
I removed the tank from my 77 Comet. I replaced it with a 24 gal Nascar fuel cell (Summit Racing) mounted in the trunk over the rear axle. I cut the rusted out floor from the trunk and covered it with a piece of flat aluminum plate sealed with floor tar sealant. I also installed an aluminum bulkhead in the front of the trunk behind the fuel cell. I thus I increased the weight over the rearend and increased the fuel capacity.
I’m thinking about building a steel box that would drop in like the original tank to replace the gap in the floor. The fuel cell I was looking at is a 22 gallon 24x24 10”deep. How did you run your filler neck tube ? Or are you just popping the trunk to gas up. What did you end up doing for your vent system
I just pop the trunk open to fill it. I have a vent hose that runs down into a hole that's on the inner side of the rear fender pocket. Both it and the fuel line have a ball valve on top of the tank to shut them off while the car stays parked in my shop (for weeks sometimes) The tank is wedged against the firewall I installed behind the rear seat. using a piece of 2x2" aluminum angle bolted to the floor plate. There's not enough room around the tank for it to move while driving. You'd have to be in a violent rollover wreck for the tank to come out. I've run an in bed tank in a V8 Ranger where I used the old return line routed back to the aircleaner as the tank vent. I just didn't feel like running a new line for this with the Comet. With this system any tank fumes accumulate in the air cleaner and are sucked into the carb when you crank the starter. It both richens the mixture (in theory) and vents the tank. I removed the old tank filler cap and pipe assembly and plated over the hole with another piece of aluminum. I made a mistake on the volume, it's a 22 gal, Summit part number 290114 Fits between the wheel tubs and has 8 inches or so clearance under the rear package tray.
