EFI Fuel Tank

[lalessi1]

I got the EFI tank and I LOVE IT! It is larger than the stock tank and the pump flange is an SAE standard. It will accept the Tanks Inc. GPA series of pumps and it has a baffle built in around the pump pickup. The sending unit flange does not use the '57 retaining ring (which I  don't like) but it will accept many different sending units including a universal one (10-73 ohms) that can be adjusted to fit the tank. Also the filler tube has the correct depth on the cap lock so the cap I will have a tight seal unlike the Auto City tank I now have. There is a vent line connection on the tank in the stock location and another vent is on the pump outlet as well. The tank comes with the straps and a drain connection. All in all it is PERFECT and it addresses several issues I have with my existing  tank.

That's a good-looking tank, lynn! Great price too. First time I've seen pics of the drake tank with EFI setup............wish they were available many years ago. Strange your auto city's filler neck is not correct for the cap, First I've heard of that issue. The sending unit flange should be easier to deal with also. I had to piece together a unit to get the '57 style flange on a new unit.
Larger??? that's a surprise!

I ordered an efi tank as well.   I've been dealing with heat on the fuel issue(fuel boiling at the pump & in the carb bowl) on hot Texas days with the external fuel pump as well.   An in-tank pump should be huge advantage once I get the fuel pressure worked out to my F-Code teapot carb.  I've already plumed a return line and have an Aeromotive boost referencing regulator so it should something I can quickly dial in.
   
I'm a little concerned with the fuel sender issue, so keep us updated on what you end up using.

Is the tank plated or painted?   I ordered a couple wagon tanks last fall and they showed up with just metallic silver paint instead of the plating they normally have.  I really prefer the plating.

[hiball3985]

Good question. What were the original tanks plated with?

What I am curious about is the proximity of the fuel pump to the sending unit. The Tanks Inc pump has a fairly large baffle/box, and I seem to remember a non-symmetrical hole pattern at the flange to ensure the pump is located in a front-to-back location.
The tanks Inc sending unit I used had a bolt-on flange rather than the twist-lock type. That bolt-on flange is what I removed, but maybe what is wanted for the Drake gas tank. The Tanks Inc sending unit is really well made, and available in many of the common OHMS ranges.
As mentioned before, attention will have to be made in regards to the floor brace at the back of the tank location, and I would recommend making some fittings that have the metal tubing run to the backside of the tank, and then down 3" or so for the flex lines to hook up to. Metal tubing is going to require a lot less clearance space than the rubber fuel line.

I installed the sending unit yesterday. The design is an universal one that comes in different ohm ranges. It is adjustable for depth and orientation. The flange is asymmetrical and only fits in one position but the sender can rotate. The float faces the rear of the tank and clears the baffle (barely). I checked the ohms with the float at the bottom of the tank it was 72.8 at the top it was 8. The sender is very well made and easily adjusted. The only mistake I made was the instructions have the top of the float set at 1/8" below the sending unit flange. I neglected to note that that flange is about 3/4" below the top of the tank. The distance to the top of the tank (not the sender flange) should be used to set the depth of the pivot point....

The tank is painted with some some kind of coating on the inside?

I ordered the GPA-4 pump today. Rich I already noted your advice out the fuel lines and I am waiting to see how the pump sits to make a plumbing arrangement.

I finally got the fuel pump in from Summit. Fed Ex took 10 days to deliver it! I bought a GPA-4 pump made by Tanks Inc., believing it would match the flange in the tank. Long story short it was too small to bolt in. I looked to see what I could find that would work but I couldn't seem to find a universal design with the same flange fitment. After a little thought I decided to make my own using the flange block off plate that came with the tank. I ordered two 90 degree bulkhead fittings, two AN to hose barb adapters, a fuel cell electrical bulkhead for the pump wires and an Aeromotive 11540 fuel pump. Summit will refund the cost of the GPA pump and the difference is about 75 bucks but I get a 340 lph pump instead of the 255 lph Tanks (Walbro) pump. I will take a few pics of what I am using when I get all of the parts assembled. I am moving ahead towards the fuel injection purchase. I am now leaning towards the The Holley Terminator X Stealth 4150 system. It uses a throttle body that looks like a 4150 carburetor but the ECU mounts separately along with the pressure regulator unlike the Sniper system.

I noticed that Drake has a Universal Fuel Pick-Up HR-9003  Which has the pickup tube, return line and wires included.   It looks like an in-tank type pump could be mounted to this and used in their tank.  I ordered one to check on FI 57/58 Tank I bought from them.  I'm planning to use  a high volume mustang style pump with their pick up assembly.   I'm going to use this pump with my carb for now with an aeromotive bypass style boost referenced regulator.   I currently have two fuel lines(one return) running to the front of the car now.   
I'll update when I get the pump mounted and figured out.

I'd be curious what pressure you run from the electric to your carb. I am going to run a 406 tri-power on my 390.

[lalessi1]

Pat, I did see that but I didn't notice the flange. I should have called them to make sure that flange will fit their pump. Odd they didn't show a pic or mention the fit in the description. I think what I am doing will work with a lower profile than the one they are selling. Waiting again on FED EX for the pump.

Hugh, I have a Mr Gasket pump that is supposed to have a "high pressure" spring in it, unknown pressure output (I borrowed it from a friend). I have a low pressure return style Holley regulator that is operating at 7 psi on the carburetor now. The issue with the pump mounted outside the tank now is that it will not pickup  fuel consistently with 5-7 gallons in the tank under even modest acceleration. The EFI tank has a box style baffle around the in tank pick up, to solve that problem. For the fuel injection I am going to need 58.5 psi so I will need a different regulator. I am planning on using an Aeromotive 13138 regulator with an adjustment range of 40-70 psi. Here is a pic of the baffle in the tank.

[mustang6984]

Thanks...I will remember that.

Well I finally received the fuel pump, fittings, and other parts and I spent the better part of a day putting the stuff together. I ordered a Tanks Inc. GPA repair kit and I modeled my pump assembly after theirs using the block off plate that came with the tank. I am very pleased with the results (assuming it works). The pump I used is an Aeromotive 11540. Here are pics of the assembly.

I finally got around to installing my EFI tank. The tank was at least an inch taller than the stock tank and slightly more square on the bottom, so rather than space the tank down I cut a hole in the trunk floor and notched out the forward floor support to run the lines. I used a 1/2" aluminum channel riveted to the floor to space the cover up for line clearance. I can now replace the pump without dropping the tank. Holley delivery on the system I am buying is 1/21/22 right now, but I am getting closer. I also reinstalled the mechanical pump so I can drive the car in the meantime. It is running really great in the 70's weather we are having now.

[mustang6984]

Clean install...looks really good!   

[RICH MUISE]

Notching the floor support, or drilling big clearance holes, is what I should have done. Good job. Now that you're going to have an electric pump, you may want to install an impact shut off valve. They're easy to find in a junk yard.....5 bucks
