67 RS w/LQ4 and Tanks Inc fuel system

[armourmark]

Last weekend I finally started moving again on my 67 camaro. I installed the Tanks Inc new tank system. I could not be more pleased with the tank!! I was waiting for a long time to find a tank that would meet my needs and my budget and this one is it. Here is a picture of the tank. It comes completely powder coated and is a very quality piece that is powder coated inside and out. I called Tanks Inc and spoke with Georgia and Jason several times and they are both very knowledgeable and willing to help. Here is the tank:

I am looking at their setup as well. Keep us posted.

Here is a pic I tried to get of the fuel tray inside the tank:

Here is the parts list from Tanks Inc with prices:
TM32A-T 67-68 Tank with F.I. 210.00
GPA-4 GPA Walbro Pump Assembly 220.00
TAN-GML 0-90 Ohm Fuel Sender 35.00
ST56 67-69 Fuel Tank Straps 30.00
CA67-68 67-68 Fuel Filler Neck 30.00
SL24 24" Strap Liners 5.00

The tank pump comes with a nice vent and brass fittings for supply and return. Here is a pic of all the goodies:

[armourmark]

The instructions that come with the fuel pump assembly are very basic but more than adequate. Step 1 is measuring the depth of the tank. Then you follow the instructions and trim the supply and return line to specs. Here is a pic of the tank depth:

[armourmark]

This is what the fuel pump assembly will look like after you trim and attach the lines. You also need to zip tie the pump to the return line and attach the sock. Very basic and simple stuff.

[armourmark]

This is what the fuel sender will look like when trimmed. The instructions with the sender are very detailed and easy to follow:

[armourmark]

All the gaskets come with the fuel pump assembly and sender. The instructions said to use indian shellac gasket sealer, but I choose to go with permatex aviation gasket #3 as it does not dry hard like the shellac. You apply that to both sides of the gaskets and then fasten the pump and sender in the tank. At this point, you will see in the next pic I marked the supply and return side with marker on the brass fittings. I also should mention I marked the positive and negative for the pump and sender before I installed them in the tank. You will also notice the 1/4 npt to 3/8 hose barb on the return side (since there is very little pressure) and the 1/4 npt to -6 AN fitting (summit part #FRA-481606). I also use the permatex on the threads of the npt to AN adapter on the npt threads only (the ones that screw into the brass fitting)

[armourmark]

Here you will see the Wix filter/regulator (summit part #WIX-33737) and the fittings needed to make the connections. The brass is a 5/16 compression to a 3/8 hose barb that I made up at my local hardware store for the return line. The supply is a russell quick connect fuel fitting (RUS-644123) with a straight AN -6 fitting. On the outlet side, it is the Russell fuel rail adapter fitting (RUS-640940) and then a straight -6 AN fitting.

[armourmark]

This is where I put the filter on my frame rail in front of the rear tire.

You will want to connect all of your lines on the ground before you try and put the tank up in place. Be sure to label all the wires so you don't have to trace or guess later.

[armourmark]

I tried to get a picture here of the clearance. This pic is kind of deceiving as there is plenty of room. Not enough to connect or disconnect anything, but definitely not cramping anything.

[armourmark]

This pic shows the way I secured the lines with self tapping screws and used insulated steel hose clamps. I did not take pics of me putting the tank in place but one recommendation I would make is to use spray adhesive and stick the strap liners to the straps with it. This way you are not fighting with the liners trying to bunch up and move around on you.

[armourmark]

This is a shot from under the car looking out the back at the finished product.

[armourmark]

Here is the finished product!! Major upgrade to the factory tank in looks. Works perfect so far and is quiet. The other thing you will need is the filler neck to tank hose and clamps. I reused my clamps, but I went to oreilly and picked up a Gates hose (part #23932). They sell it by the foot and it cost 7.99 for 12inches. You will only need about 4 inches.

What fuel line are you running to the front?

[67Soto]

Great write up! Thanks for the update and pics!

[armourmark]

What fuel line are you running to the front?

I am running -6 line. Fragola Series 8000 Push-Lite Race Hose. I flipped the fuel rail around so the fuel outlet is now on the passenger side and connected with the russell quick connect fuel fitting (RUS-644123) into a 90 degree fragola fitting.

[armourmark]

It was brought to my attention that Tanks Inc does sell the tank to filler neck hose under part #GH-2 for $10. That makes the setup a total one stop shop!!

[armourmark]

They are always developing new products/applications at Tanks Inc. They have recently redesigned their tri-five tank to have a more recessed top like the f-body one.

Nice, ordering mine next week. Thanks for the review.

Im about to buy my fuel lines what size did you use for the return and the feed line to the pump, this is my first time doing any fuel lines so any advice will be much appreciated, FYI im getting my fuel lines made by a guy at the local high performance swapmeet. Did u run a single line stright from the regulater to the fule rails?

I ran -6 AN lines (3/8 line) for the supply and return. The return calls for 5/16 but since it's not really pressure sensitive, it doesn't matter what size on the return. I did run a single line from the regulator to the fuel rail, also -6 AN size. I bought 20 feet of -6 AN line and it is more than enough for the supply and return.

Nice write up.

I know this is an older thread. But I have a question before I purchase one of these tanks. Why do you need 3 lines coming out of the pump? I understand there is a feed and return line, but what is the third line for? Also on the WIX filter/regulator there is one line going in and two lines going out, why two lines going out and where do they go to? Sorry for the questions but I am trying to understand all this before I purchase.

I just purchased the Atomic EFI from MSD and really do not have a place to mount the pump and filter on my 67 camaro. I am looking for options and this is one of them.

Thanks, Erik

The 3rd line is for tank vent. On the Wix filter/reg, the side with 2 lines-the center line is the return line, the one offset to the side is the inlet coming from the fuel pump. The other side goes to the fuel rail.

Here's a picture with the C5 reg/filter. To the right of the filter, the bottom port is the feed line from the pump, the other line is the return line.

It installed. The AN hose is feed line, rubber hose is the return line.

Nice!

However, that hose will eventually fail in service. Not tomorrow, but eventually. You need to use PTFE or rubber hose rated to SAE J30R9 (or even better J30R12). The Fragola hose is neither.

So you do have a return line coming all the way back from the engine correct. The pic is a little deceiving for me at least. It looks like the return line goes from the tank right into the Wix Filter/Regulator?

I am trying to plumb an Atomic EFI kit and might as well just buy the Tanks Inc tank, so I dont have to worry about mounted an external pump and everything. What is the Wix Filter/regulator set up for pressure? I need around 43-45 PSI I guess.

Thoughts on the best way to handle my setup?

Thanks, Erik

[Erik Beckett]

Also, what kind of electrical connections are needed for the sending unit and the pump? Sorry for the dump questions but I am green when it comes to EFI.

Thanks, Erik

[rickpaw]

John,

I saw that thread when researching fuel lines for my swap. Down the road I will update the fuel lines. Shouldn't be too hard or expensive since the majority of the system is hardline. This will get me going for now, since the car has been down for awhile.

Thanks for the heads up.

Depends on where you have the filter/reg. The return line goes from the filter/reg back to the tank. I have mine mounted just in front of the tank, so the line is fairly short. The filter/reg is set up for 58 psi, I think, for LS engine.

For wiring the fuel pump, you need to wire up a relay, using the EFI or an ignition on circuit to trigger the relay, which in turn turns on the pump. The Tanks Inc set up has 2 posts on top of the fuel pump module. One for ground, one for pos. power. The pos/neg wires should be at least 12 gage, 10 preferred.

[Erik Beckett]

Rickpaw, Thanks for the quick responses. I am totally new to this so all the help I can get the better. I have to ask, why is the return line not plumbed up to the fuel rail at the engine? Your saying it goes from the filter/reg to the tank? You have to have a feed line to the front of the engine and a return line coming all the way back correct?

Tahanks, Erik

Someone else can chime in and correct me if I'm wrong, but LSx based engines use a returnless fuel system. I'm running a LS1 fuel rail, and it has one fuel inlet.

If you're running C5 filter/regulator, the return line goes from the filter back to the tank. So if a C5 reg is mounted close to the tank, your return line will be kept fairly short.

[LUV2XLR8]

correct ... the filter/regulator will provide 58lbs of pressure to the rail... and have a feed back to the tank for the regulated fuel. The placement closer to the tank will provide a shorter return line.

UPDATE- I had been meaning to update this awhile ago. I have since changed all fuel lines over to PTFE hose. The hose I originally used, Fragola 8000 push lite race hose, was permeating and leaving a horrific gas smell while sitting. I HIGHLY recommend John Parsons advice above and using PTFE lined hose from the start.
