Ive gotten the 502 installed and I was about to hook up the fuel pump when I realized that the Holley Red pump that I have has to be gravity fed. The problem is that I have a stock tank on my 66. Will the Holley Red pump pull gas out of the tank to itself or do I have to buy a fuel cell that has a sump on it? Does anyone run a stock fuel tank and a 502? I cant believe I didnt foresee this.
Do I NEED a fuel cell?

I feel your pain fella.... Let me tell you my ordeal. Dads car is a 70 chevelle. We have a nice new reman tank in it. We decide the car NEEDS a Ramjet 502. I priced and compared fuel pumps until I was sick of them. Bought a custom fabricated in tank TPI pump from Rock Valley antique auto parts. It came with a sump to weld underneath, and you weld the TPI part inside the top of the tank. Problem is NOBODY would touch the thing. They said they either would not weld a tank or it would warp, burn through, wouldn't hold up, etc.... SO I called Rock Valley, and ordered a new stainless tank. I sent back the Pump and had it put in the tank. I just got it and its 76 pounds of one beautiful fuel tank. They can fab up what you need for the stock location and everything, but its stainless so its expensive. Jegs or summit sell sumps to weld on the bottom of your fuel tank, but good luck in finding someone to do it. Also, pricing a quality pump and doing an in-tank vs. external pump, I found that for a fuel injected application the rock valley set up was the only way to fly. roughly the same price when all is said and done, no worries, and it LOOKS professional. This may not entirely apply to your carbureted application but I hope it helped you some. You may even want to fuel inject it one day!

How much did that tank run ya saturnstyl ?
I dont want to spend 600 dollars a fuel tank. I dont want to go with a fuel cell either as I have 3 12" kickers back there already. I just wanted to know if the Red pump has to be gravity fed. Or is there any electric pump that doesnt have to be gravity fed? If the Red pump has to be gravity fed and there isnt another pump that I could use, then I will go with a fuel cell. if that turns out to be case, I would like to know what you guys that have them recommend.

Your best option would be suck it up for a new fuel tank and have a sump welded in. I don't blame anyone for not wanting to weld a used tank. I have seen plenty of guys use an electric pump out of a stock tank with good results... but regardless I think you need more pump then you have.

The red pump does not need to be gravity feed. It just need to be mounted low. Take a look, there is a frame piece that the upper control arms mount to. It is just forward of the tank, at least in both my 66 and 67 El Caminos. On my 67, I mounted a flat piece of 12 ga steel (about 3/32" thick) to this member and mounted the pump to this. The pump is about even with the bottom of the tank. The pump only has to lift the fuel the distance from the pickup to the outlet of the tank, and only when the fuel level is below the outlet. Once over this small hump, it is gravity feed by a siphoning effect. Works great for my rather slow bracket car (mid 7's in the 1/8). It's easy to do it this way and if it doesn't work you're out very little time, money, or effort.
As for welding a sump in, my nephew welded his in himself (he's a professional welder). He said it was a nightmare. If you do weld, be sure to use a nitrogen or CO2 purge.
The Captain's right, you may need more pump.

Letsee the tank is 885 bucks but that INCLUDES the $300 for the fuel pump that is installed. It looks sweet too, its recessed from the top so the lines fit up there, and the tank is a little deeper to accomodate the pump. Comes with straps and neck too. Do a web search for rock valley antique auto parts. I haven't gotten to use the tank yet, but so far I can recommend them.
Most radiator shops will do welding on fuel tanks. Atleast I've never had problems having them do them. Just have them weld in a 1/2 NPT bung in the rear of your stock tank. Also why is everyone talking about changing from a red to a blue pump when all that is differant about them is the pressure spring ? I had a Holley Blue on my Car and a Red pump on my engine run stand, blue pump went bad, took the spring from it and put the red pump on my car w/ the blue pumps spring and the pressure was right where it was. Lasted for a few years on the car and is now back on the run stand since I put a BG 280 on the car.

I just had a Competition Engineering sump welded to the bottom of my '70 stock tank at a local radiator shop...$60. Included cleaning the tank.
