ERA Fiel Tank Mods for EFI
I am researching putting an eight stack EFI on my ERA 289. Has anybody had experience modifying the stock ERA 289 tank for return lines, vent, in-tank fuel pump, etc. for an EFI system.
Thanks! Kim |
The FIA tank sits above the rear suspension, the 427 tank is behind it. They share no parts and are a completely different design.
The tap on the FIA tank is on the center/bottom. It's difficult to put a return line in any place but proximately close to that one. The other alternative is to install a separate tank somewhere that takes a feed from the main tank and runs two lines to the front: feed and return. There's some room behind the left rear wheel that might be OK for a custom tank. |
Thanks for the clarifications, Bob. I'll edit my original post to keep the 427 crowd away. Would it be possible to install a return line on the top of the tank and use a rigid tube to get the return fuel to exit low in the tank? I've heard it's not advisable to have the return fuel enter the tank above the fuel level.

Copy that...thanks Bob! Is there a schematic of the tank construction so I can see where the interior baffles are placed?

Can another tank be ordered to accommodate the in tank fuel pump and return line? I know there has to be other FIA 289 owners that are running EFI, what did they do? Are there any other options for in the tank fuel pumps and EFI?
|
We can probably modify the tank for an in-tank pump but I'd like to have the pump to confirm. If it can't share nicely with the sender, we might have to start from the beginning. What in-tank pump do you want to use?
|
Thanks Bob, can you send me the schematic so I can share with the pump manufacturer to find a good fit?
Thanks, Craig |

Take a look at Holley's new EFI in tank pump. It is designed to replace your current pickup and does not require a return line. It also has a hydramat to prevent fuel starvation.

Thanks Chicagowil! I also came across this from FiTech. For those who might need to use a secondary tank. Holds 1/2 gallon of gas. The Force Fuel connects to a stock mechanical or electric fuel pump then supplies the EFI system with high pressure through the use of an internal 340-LPH pump.

Bob, How can we figure out if a standard tank can be modified or if we have to look at other options? Will these fuel pumps work? One is returnless and the other is a return style. Please advise.

Both of those are about 1.25" tall, so will require a well installed into the top of the tank. The one we use on the 427 tank might work. If not we can fabricate a custom dish.
Still, I'd recommend an external surge tank instead. It's a lot simpler, especially if you ever have to service the pump. |
Great, thanks Bob!!
|
Bob, Where is the best place for the surge tank? Behind the left rear wheel or somewhere else? What size space is available behind the left rear wheel and if a surge tank is secured there, can a return line be run from the primary fuel tank to wherever the surge tank is located?

Look at what spare space you have within a rear wheel well, as example.
I have seen many cars modified in this way, and even high horsepower EFI cars. Your current tank needs to supply the surge tank with a low pressure pump, typically a Holley electric pump meant for carburetion. https://www.enginebasics.com/Advance...ge%20Tank.html Fuel surge tank example: https://www.ebay.com/itm/Universal-F...YAAOSwEeFVBCEE |
On an FIA car there is a compartment for the battery behind the right rear wheel. I imagine it would simply be replicated for the most part on the left side - should be room for that tank and pump if you can imagine it to be the approximate size of a car battery.
