Model A gas tank

I've decided against using the original tank. I think it will be in the way of the firewall recess and the room can be better used for something else. gonna try to fit a tank behind the seat in the rumble area.

 

Smilin Jack. I cut down a late 60's early 70 Ford F100 tank, sectioned about a foot out of the middle and installed it behind the seat in my '29 roadster. Still has room in rumble seat certainly for smaller passengers.
For what it's worth, I'm very pleased with it and the location. I also moved the filler to the center.

 

Thanks for the info Billy!

 

It's just a good tank and I hate to cut it out. Don't hate to enough not to do it though. LOL

 

You can trade a good one to somebody who wants one for their leaky one .

 

I'm asking, didn't they make a model that had a cover over the tank.When the day is over only you can make that call, mine has been there for 80+ years and no one has died yet. dissensions dissensions

 

I also cut out the stock tank to make room for guages and a glove box. I got a small tank back behind the rear seat of my 30 tudor, my first thoughts were safety with the tank over my lap an all , but i bet it's not much better than a tank in the rear. I do have a steel panel between the tank area and the interier of the car.

In the end, I like the look of my new dash (39 ford) and glove box.

 

I'm going with a skinny fuel cell behind the seat on mine. Not so much worried about the gas in front of my chest as the rivets for the dropdown and choke rod bracket loosening and leaking. I'm using the tank to house some electronics and wiring.

 

Safety wasn't a concern for me at all. I just need some room for the recess and room for guages and other things behind the dash. If we have a wreck in one of these things, we have trouble anyway. LOL

 

I have been thinking about this too. If the tank is as wide as possible from side to side, and stands behind the seat, it could hold a lot of gas and still take up maybe only 6" of the floor and your rumble seat passengers can be happy. You could also mount that tank 4" above the floor for a toe space.
Its not hard to figure the gallons but I am 300 miles away from my A and cant do it for you. I would like to know.

 

Looks like you've already made up your mind but I thought I'd add my 2 cents since I'm the only guy responding that's using an A tank.
There really is no problem using a good Model A tank. I've been driving this car for years with one. Absolutely no fuel smell at all. I replaced the old shut-off valve with a good quality stainless ball valve and I shut it off when not driving. Reason being, the tank is above the carbs and there is always a little push on the fuel due to gravity. It's not enough to seat the needles in the carbs and they weep a little otherwise.
As far as fuel gauge goes, I turned down a SW sending unit mounting plate to fit in the original gauge opening. This cuts off all the holes around the edge. Then I bent the cork float stem 90 degrees to reach the bottom of the tank...works like a charm.
Counter to what's been posted here, there's still enough room to use a 32 style dash in front of the tank with lots of guages. All my wiring is routed behind the kick panels and under the seat. the fuse panel and the dry cell battery are behind the seat. ..leaves alot of room for trunk storage.
It's hard to tell from the pics but the firewall is recessed 4". The recess is all below the tank.

I am also running the stock gas tank in my '29 Tudor. My motor is a '79 Buick V6. I do not have the fuel pump hooked up; gravity feed only. I did 1600 miles in one week last summer, no problems. This included going over the Duffy Lake Pass into the BC interior. I also use the stock gas gauge. Wayne.

 

Flthd31, that car is soooooo fine!

 

It took a little finagling but I used the original tank in my 29 coupe (running a flathead), even kept the stock fuel gage and ammeter. I made a new face plate for the instrument cluster, replaced the stock speedo with a Smiths dual mechanical temperature/oil pressure gage, mounted a Smiths tach and speedo on the column and hung a Veglia Borletti clock and Smiths vacuum gage from the old choke mount (The instrument cluster and and tach/speedo pix are early photoshops but the final product looks just like them). IMHO, still the safest place for the tank in these cars and the cool factor was worth the effort.

I tried to convince myself the gravity feed would be fine for a flathead but there just isn't enough head with the stock tank to even keep up with the 2 psi Holley 94 supply requirement and the flow demand at highway speed. Ended up putting a stock mechanical pump back on the engine.

 

Flthd31, I like what you have there!

 

Save your tank and resell it. Buy another that perhaps has already had the tank portion removed or leaks.

Here are some shots of my F100 modified to go behind the seat. There is room underneath for passengers toes. I built a frame work out of sq. tubing.

 

I have been working around the same problem. Stock tank was already cut out so I filled the dash hole with a gauge cluster and put the electrical system back there.

Found this tank and got it today, should work great as it's 18 gallons and I'm going to build an enclosure for it. Need the room for a rear seat of some kind for the grand kids when they come over.
