The fuel pump had to be back ordered, so it took longer than anticipated. The tank itself was manufactured in Canada. It was imported through a company in Vermont, and sold by Mancini in Michigan. It looks like a very nice quality OEM piece. The cutting and welding for the fuel pump looks very neat, and precise. It is not painted, so I will have to prime and paint it before installing it. The weather is getting better here, and I am through some of the extra tasks and activities I had taken on, so I will get to this within a month or so. I had said I would e-mail a photo of the tank to Pierre, which I will so some time in the next three or four days.

Sounds interesting. I may have to get one for ripping out my stock tank with my metal spaghetti of lines and surge tanks.

Sam - I'll post them for you when I get them if you'd like.

I'll send some photos to both you guys.Maybe can get to this on Sunday. I have a question about how to plumb the vent. This particualr tank has four vent tubes coming out the side of the tank at the upper left rear. My plan is to route this to a charcole canister in the front. Does anyone know which one of these outlets is prefered? The two rear ones look like 3/8" and the two front ones look like 5/16". Why were there four in the original set up. This tank is for a "72 and later.

The 4 vent tank was for the california only 70-71 setup. Next to the fill pipe in the trunk there was an almost vertical tube about a foot long and probably same diameter as the fill tube. This tube, dubbed the vapor separator, had 5 lines coming out of it - one for each vent, and one to the filtering contraption on the valve cover. Inside the tube, the 4 vent lines were all shorter then the line going to the valve cover, so if any liquid fuel sloshed into it the vapors would rise and be sucked out. At least thats how I remember it working.

It used the crank case to store the gas tank vapors and then the pcv sucked them into the engine.

Interms of your application - I'm not sure what the difference is amongst the vents - last time I remember looking in the fsm each one went to a corner of the tank but I didn't think there was any other difference.

you got pics of the baffled inside? did you baffle the inside?

The fuel pump sits inside a sump which sits down inside the tank. There are no baffles other than the walls of the sump. Rick's Hot Rods claims this is the way OEM tanks are made now. The return line empties into the sump which then overflows into the tank. I assume , but don;t know, for certain, that there are some openings into the tank from the sump. There must be some way for the sump to fill from the tank supply. Someone else on this forum has one of Rick's tanks in their Dart, and is quite happy with it. I haven't taken the pump out to look at it. It is assembled with stainless torques screws. The sump and pump are stainless as well. I don't know if the gasket is cemented in, in which case I would be ripping the gasket apart to disassemble everything and inspect its construction. I guess I might do that for the benefit of members who are curious about the construction, and just try to be sensative to how things are coming apart.

I still have intentions of having a short section of fuel filler tube welded into the tank, and then connecting this to the fuel filler with a section of rubber hose. If I do that, I would more than likely remove the pump to protect it from the heat of the welding. An earlier post has someone saying this is the way the vans were made, and that this rubber connecting hose can be purchased from NAPA. It seems like this would control the seal better, and make assembly easier as well, since you have to insert the fuel filler pipe down through the hole in the tunck floor while the tank is kind of half way in place. I always thought that was pretty akward, and treated the gasket at the tank filler opening pretty roughly. Maybe this is an unecessary concern and bother.

I'm remembering a '72 parts car I had some time back. It had this style gas tank in it, as well as a small collector tank up in the trunk. I do not remember how it was plumbed, but there was a spider web of rubber gas line hose associated with it. I am wondering what keeps the vent line from becoming a siphon and draining the tank into the charcole canister when the tank is full? Is there a chamber at the top that the fuel does not get into directly? It is interesting how many things in car I just take for granted, and have never thought about how they work, even after years of participation on this forum.

Sam, there was no charcoal canister for the 70-71 california setup. It used the crankcase as the storage, not a canister.

I believe the vents were baffled. That, combined with the vapor separator prevented any liquid gas getting sucked through to the crankcase.

Can you give us an idea of how much the tank set you back?

(I'm almost afraid to ask, 'cause I'd REALLY like one someday... )

Total cost was $695. If you supply the tank, that cuts the cost down to $495. They can do the same thing to an old tank. I could have sent them an old tank I have, I just wanted a new one.

Does anyone know how these four vent pipes should be plumbed? Can I just put them all into a manifold and route it to the front. I would think a charcoal canister would work, even though the original didn;t have one. I am routing the current vent hose into the intake tube.

WOW. Thanks for the info — that's WAY cheaper than I was expecting!

Here they are. Sam I hope you don't mind I took some artistic liberty to crop/resize so they are more forum friendly





Sam, any way I can bother you to take the sump out and take pix of the sump itself and how it mounts in the tank? Or maybe you can take the pic through the original sending unit hole or fill tube hole?

As for the vents - I'm not sure how well baffled they are on the inside - If your going to build a manifold you will have to put it pretty high up to avoid splashing any liquid gas into them on turns. Let me check my fsm and see, I thought I recall some descriptions/pictures of that system in it.

>Can you give us an idea of how much the tank set you back?<

The all-stainless steel tank Rick' Hot Rods fabricated for my '63 Dart cost $1200.00.

It's much heavier than the stock tank. At the time I ordered mine, they did not offer the modified stock tank.

Mighty pretty, though, either way.
