Thread: Boat blower for trunk ??

Tweet

I am doing a Graffiti coupe and I will have to run a fuel tank / cell in the trunk. Seeing I have never run a tank in the trunk, I have a question. Should I run a vent blower like they run on boats for inside the trunk to expell vapor ?? I'm a touch allergic to fire... makes me blister....

I'm running a tank in the trunk, too, and I'm working on a bulkhead that will seal off the trunk from the passenger area, glassed in on all sides which is probably overkill. The tank has a vent/rollover check valve, and that vent line will be run out through the floor, flush on the outside. As long as I don't dribble fuel when filling I'm not concerned with flammable fumes. Many older pickup trucks had the fuel tank right behind the seat, with the filler on the side of the cab.

Just what I was looking for.... Thanks !!

I don't think there are any pics of the fuel system of the 32 in my gallery---but the owner didn't want the fuel tank in std location so he could see the IRS---I said no prob they make tanks for the trunk--he said in some pretty specific terms about not wanting the fuel inside the car

I built 2 stainless 8 gallon tanks that fit forward of the rear end assy and short of the trans crossmember one on each side of the driveshaft filled by a LeMans cap on top of rt rear quarter with cross tubes between tanks for transfer and fill/venting

I'll try to find some pics in the build photos and post them

I did the same thing as Roger when I built my deuce. Overkill or not, it makes me feel safe.

Not to hijack the thread, but what material did you use for your bulkhead behind the tank?

Hey, Pintos had 'em and they were safe.. Okay, I'm kidding. I too had a cell in my trunk. Removed the 8 gallon and am in the process of having a custom 14 gallon tank made to fit over the tubbed wheel wells to give me some trunk space. I am however going to run the filler tube to the outside as I hate having to wait for the actuator to open the trunk for a fillup..

I like to use .090 aluminum for a fire resistant bulkhead, then seal the edges with seam sealer or structural adhesive....

OK, a question. Why worry with a fire resistant bulkhead be in a glass bodied car? It seems to me that a 1/2" plywood panel sealed as noted should be equal to or better than the fiberglass it is connected to.

Yeah, probably so, Rog.... Fiberglass goes up quick!!!! A quality tank vented to the exterior is by design quite safe... Big thing with me is just not having to tolerate any gas fumes in the car, gives me a headache even if it never would start on fire....remember the stinky old pickups with the tank behind the seats????
