EFI Tank

[WildJones]

I'm thinking about getting one of their stock replacement tanks and internal pumps for my carbureted car.  A great alternative to an externally mounted fuel pump and just have to regulate and install a return line.

The best solution to vapor lock for low pressure applications.

Msbaugh,

I bought my setup with that exact intention in mind. I may go with an EFI setup now or down the road, but at least I know the fuel system is prepped ahead of time.

Also, FWIW for those trying to save a few $$$ Summit carries their products and I think I saved something like $40 buying from Summit vs the listed Tanks Inc prices.

Yes, I agree. Buy from Summit Racing.
I called Tanks Inc. and explained that I was going to be placing a fairly large order and asked if that could at least match the Summit pricing.......I was told no, go figure?

[ff6849]

The same thing happen to me buying from another vender, they wouldn't match the Summit price. the vendor told me that Summit negotiates that in their deal with the vendors.

Same here, I got a better price on my Vintage Air system from Summit, YO said the there was a long delivery time, (months) Summit shipped it in a week.

It pays to shop around.  I've seen the Phantom setup on Amazon for a few hundred dollars less than what Summit was asking for it.

I'd like to know more about this.  I would like to eventually do a Gen 3,swap.
Do you need to get a low volume pump for the old engines, then upgrade for EFI?

Just run a regulator that can reduce pressure to around 7psi. You could also get an in tank pump that doesn't pump at high psi, but then you'll need to buy another pump and regulator when you switch to EFI. Keep in mind different EFI systems run different pressures to the injectors. I'm not sure what psi Gen 3 Hemis need. 58? 43? Idk.

My dad has a Mallory pump mounted on the frame rail in his 69 Dart. When he switches the ignition you can hear the pump, both in car and outside. It sounds cool, but I don't want to hear the buzz/whine while driving around so I'm trying out the in tank setup this time around. I've read lots of great things about Tanks Inc so I took a chance. I needed a new tank anyways and the price was close enough.

That's what I'm doing - running carb at first and then switching to FI.  Using an Aeromotive "universal" regulator, part #13301.  Comes w/ two springs - one for carb pressure (3-20 psi) and another for FI pressure (20-65 psi)

I'm in the middle of an EFI swap now. I'm running Megasquirt 3, I'm already running the MS3X on ignition. My distributor is gone and it runs on 8 coils.

I'm moving to the fuel side now and my thoughts in doing this is one step at a time. I got the ignition working so now I just have to run fuel. I am going to convert the fuel SYSTEM before swapping to efi as well. That being said I'm using the Tanks Inc tank, pump, sending unit. I just ordered the parts so its not installed yet.

Aeromotive makes a regulator that works with EFI and Carb (#13301). So like Shawge Ill plumb the entire fuel system for EFI but keep the carb on until i'm ready to add the TB, injectors and fuel rails. It also allows me to spend money bits at time instead of all at once.

IMO The Tanks Inc is the way to go. Walboro pumps are great pumps and a widely used in the tuner/modern car world. I considered the Aeromotive pump but I think the tanks inc route is a much better option because you aren't hacking into anything. You can still keep your old tank or sell it or whatever.

As has been mentioned previously, yes run fuel to rails first so motor always has full delivery availability from the pump.  Regulator after rails then regulates pressure using the remaining unused fuel. 

I currently have an external Walbro pump setup with a return line. I also have rails mounted but they are temporarily plugged so I can run the carb. Here is a pic showing the feed line up front and the regulator on back end. I will say since this return style setup was put on the carb its startup has been much easier. Bowls are always filled when pump switches on.


When EFI is finalized the feed line will Y split to the front of rails and then the regulated return out the back.

One question for those who have experimented with these walbro, in-tank pumps on there 440 big blocks.  Which model did you order? 

I see they have 3 basic in-tank options (all of these flow rates are at 0-10 pounds of regulated pressure):
-In-tank GPA-02   ---> 54 gal/hour
-In-tank GPA-04   ---> 82 gal/hour
-In-tank GPA-06   ---> 105 gal/hour   

Comparing to similar flow rates with mechanical race pumps it sounds like the GPA-06 would be the ideal pump for a hopped up 440

I'm going with this setup as well. I will start with the existing carb but after everything is back up and working properly I have a F.A.S.T. EFI unit I will put in.
Let know how everything works out.

Cheers!

I think this is what YellowThumper has for the fuel line routing and is what I plan on following. 

The carburetor routing differs from the Tanks version with the regulator being after vs. before the carb.

You are exactly right, this is the best way to route it as fuel is always moving and the carburetor isn't dead-headed.

There is one problem with this though, you're return line is what governs the feed line pressure. If you have any of the high psi/flow pumps I mentioned in my previous post and need to get feed line pressure under 10 psi for the carb you will have problems.  The only way to ensure that the regulator can keep pressure low is to install a huge diameter return line.  This means -08 or 1/2" tube at a minimum.  I just had a long conversation both with tanks inc. and aeromotive techs discussing this.

The only issue I then see from this is that you'll have a tremendous amount of fuel constantly dumping back into the tank from the return line. My thoughts are that this could cause some serious aeration and can pressurize your tank if you don't have a  really good vent.

I was asked about how specifically my fuel feed setup is.
Here was my response and also a better pic of regulator mounting. Please note this is a hybrid setup until final EFI conversion.

It's setup is s bit unconventional because there is mostly 2 systems there. Regulator is mounted directually to the back end of my fuel rail.
But...
Because I am still using the carburetor I plugged the ID of the connecting fitting. Basically the rail is just a mount.
The current carbed setup is. Initial feed line comes up from rear of carb. T's to secondary float, continues and T's to primaries, continues on and loops under manifold runners (Air gap) and back to regulator. Then from reg it returns to tank.

EFI setup the feed line will "Y" from under runners and connect to both fronts of the rails. Currently plugged fitting will be opened by the regulator and the 2nd rail return will also be connected to regulator. Post regulated return line to the tank will remain the same as it is now.

Hope this helps.
