Help please.. Fuel Pump mounting location, using a fuel cell

I am in the process of installing a fuel cell in the trunk of my 65'... From the factory it had a drop in style tank... Anyways I made a floor for the trunk in place of the old fuel tank... Now the question is were should I mount the fuel pump with a cell... I was thinking of running the fuel pump in the trunk.. Thought it would be a clean install... Then I thought it may not be that safe having high pressure fuel in the trunk... What is your guys thought on this??? Here is a pic of what I wanted to do...


I could cut a cutout for the sump and run the pump under the car... But the pump I am running is huge... It is the Magnaflow Quickstar 300 w/filter... The pump is very large and placement would be tricky....



Do you guys think it would be safe to run the pump inside the trunk or not... This is a street/strip vehicle.... Mostly drivin on the street though... I am also making a firewall between the trunk and the passanger compartment also... Sorry for the dumb question... Just want to play is safe and do it right the first time....

I feel that you would have a real serious safety issue if you don't isolate the fuel tank and pump from the passenger/driver area of the car with adequate thickness of some sort of metal (aluminum or steel). I doubt if you would pass any kind of tech at an NHRA or IHRA track even for street classes without this barrier metal.

Safety should be your primary concern.....

You could buy a fuel cell that bolts into the stock gas tank location. It's a pretty trick install and I would then run the pump underneath somewhere close to the tank.

HI
I'm with juststrocken. It would be scarry [img]/phpBB/images/smiles/icon_eek.gif[/img] to have the fuel cell rupture or the fuel line rupture INSIDE THE CAR [img]/phpBB/images/smiles/icon_mad.gif[/img] I would mount cell and pump out side the car.

I don't see a problem with this type of arrangement, see it all the time. It must be isolated from the drivers compartment though as well as the top of the cell can not be higher than the top of the tires.

I agree with QM, The trunk mounted pumps are used in many many race and street cars.

Here is one set up on a local car I like.

What I did in the 67 was to build a 1" square tube frame to mount the cell. I bought an aluminium cell with the mounting tabs on it. I sunk that in the trunk level with the bottom of the bumper. The pump attaches to the side and all lines except the return are under the car. The top of the pump intrudes into the trunk a little bit. I also used .040 aluminium to seal off the trunk area and to build a new floor around the cell. Mines just about even with the trunk lip. Passed tech, so it must be good enough. You must also vent the cell to the outside. Most use a 360 loop of hose from the tip over valve, exiting the trunk floor. Your arrangement will work fine, but the NHRA/IHRA guidelines need to be followed to the letter or tech will run you off. And be sure to ground the ring of the filler cap. My wife was freaking about the cell and the battery both being in the trunk. I explained that it's not any different from the stock items expect that the aluminium was thicker than the old tank steel skin and the aluminium had more give should I get slammed or back into the wall. I also have an impact switch from an EFI car back there (wired to the pump feed) along with the required rear power shutoff.

Dyno Tom and qtrmiler....[img]/phpBB/images/smiles/icon_tdown.gif[/img]...[img]/phpBB/images/smiles/icon_lame.gif[/img]....I tend to disagree with both of you....just because idiots put them there with no isolation.......sure as heck doesn't make it safe....so...i don't understand why you two are wanting to continue promoting an unsafe situation....[img]/phpBB/images/smiles/icon_mad.gif[/img]....since neither of you stressed, as Kelly did, the need for them to be isolated form the driver's compartment...(and yes QM, I saw you state mildly the isolation part)...

Yes, you have to isolate the trunk area with a metal block off plate.

This mounting method is the way all 25.1 C cars run them.

I don't think the NHRA would tech a car to run 7.50s with a unsafe fuel pump mount.

The pump that Billy runs is a huge pump that would be very hard to find a spot under the car for.
