I was in a hurry :rolleyes:. I have an intank fuel filter with a -12an (3/4"ID) barbed hose attachment. I was using a -10an (5/8"ID) bulkhead fitting ontop the tank and 10an fuel hose as the suction/pickup. Needed a way to connect the two different sizes for my fuel pickup... cheap. Was already tapped out on all the fittings, hose and fuel system components. . plus wanted a new number for Scheid's event that upcoming weekend. So I heated up the 12an hose, muscled it over the 10an hose, clamped it together, called it good :rolleyes:. Well this lasted long enough for Scheid's event and after about 100 miles on the tank the two hoses came apart and I sucked air:mad:. Now to do the job over again and mostly right this time around. I say mostly right because the right way would be to use an outside the tank inline or spin-on filter before the Aeromotive electric pump. Since I already have money invested in this intank filter, and no room for a spin-on and didn't want to spend $100+ for a -12an inline filter, I choose to reuse the intank filter.



The first pic shows the ~3" fuel suction pickup hose I had after the two size hoses came apart. This turned my 30 gallon fuel tank into a 5 gallon tank :-laf :(. I now have this 10an bulkhead capped. 2nd pic shows the intank filter, two pushlok fittings used, length of 12an Aeroquip hose, and a 90* elbow. I know the hose clamps aren't needed for these type of fittings, but I wasn't gonna fool around with something coming loose again inside the tank. 3rd pic is the 12an bulkhead inside the tank. 4th pic is the suction/pickup assembly inside the tank. The filter sits about an inch above the bottom of the tank. It should pretty much be self cleaning as it spins on itself. 5th pic is of the new hose from the bulkhead at the bottom of the tank to the electric pump. 12an all the way to the inlet of the A-1000. The A-1000 uses 10an inlet and outlet fittings. For the inlet I've used a 10an to 12an o-ringed sealed fitting. Got everything locally for much cheaper than the expensive Aeroquip fittings out of the gasser trash catalogs. I know these are heavier, but I'm not building a racer. It maybe just my mind, but I think the A-1000 is quieter now. It's designed to be a pusher not a puller, so it's not working as hard now. I would recommend plumbing it this way. Although many have used this pump as a puller, sucking the fuel from the top of the tank with no issues.



For the -12an bulkhead, it says to use a 1 1/16" drill for the hole. I went and bought a 1" spade wood boring bit to use. This was perfect as I could finger thread the bulkhead into the tank after drilling the hole. Make sure you use the correct type of sealing washer with your bulkhead, and be sure to place the washer on the OUTSIDE of the tank. If you place it on the inside of the tank, fuel can leak past the threads of the bulkhead. The correct type of washer has a metal OD and rubber ID. Only bad thing about working with these bigger fittings, is you'll need some big tools :-laf. No leaks for far!
 
I see he has a filter. Any water might be a problem but other than that, I think it's ok. The only thing I would throw a red flag at is the fact remaining; the large fuel lines are only as effective as the inlet port of the injection pump it's self right? I only mention this due to my years in the oil field where I had to build hydraulic systems and had to keep the fittings a particular size espessially the SUCTION side.



Outside that it looks like he has been busy. I hope it gains him something for all that work.

I would be more concerned with the way that fitting hangs down so low.



As long as it doesn't catch on the dyno, it's fine for Bill's truck! :-laf Hey Bill, you wanna come four wheeling with me sometime??



Glad to see you posted your work for us to see. I suspect that it will work fine for your application. I just hope that it doesn't leak fuel for you. I also hope you don't run over a dog or deer. You might have problems getting home with no fuel to the pump.

I'd be worried about somebody with some cans cutting the hose and taking 20 gallons of fuel! :{ Or a porcupine chewing on the hose! :-laf
