Hi all. I am getting a car ready for a demolition derby. Usually I run
something older with a chevy 350, but due to time constraints I am
stripping out a 89 mercury Grand Marquis with a 5.0. It runs and drives,
so it won't take long to get ready. Anyway, I am having trouble figuring
out the easiest way to do the fuel system. Normally, with a mechanical
pump on the motor, no problem. Fasten down an outboard 6 gallon tank,
run a fuel line to it, and all's set.  But on this car, I need to  keep
the stock electric pump in the tank in use. Does this pump have to be
mounted inside a tank, or can I mount it externally out in the open? I
was looking at it today, I could take the pump off the sending unit,
take the sock/filter off, mount the pump on the floorboard, and run a
line from where the sock was to my small tank. Would this work? I see
three choices to make this car run....First, do as I just described and
mount the pump externally on the floor. Second, if the pump must be
inside a tank, I could cut a hole in the top of my small tank, and mount
the complete stock sending unit with pump in the tank...a lot of work,
and i'd still have to modify the unit because it originally mounted on
the side of the stock tank so I would have to do some
cutting/welding/bending to get the angles right inside the little tank.
Third, if the pump has to be inside a tank...I'm assuming it would be to
cool/lube the pump... could I mount the pump in a seperate gallon-sized
jug of water, and then run my line to my small tank? This way I wouldn't
have to modify my small tank, I would just have an extra small tank of
water mounted next to the fuel tank. Any ideas or comments are greatly
appreciated!!  Earl
