Fuel tank setup; experience and opinions please

I wasn't sure where to put this since there isn't exactly a fueling forum.

So as a base, I do not even have a tank so I'm starting from scratch. I'm fueling a 6.0 LS that will be 450 hp range using Holley Terminator X management system and 42 lb/hr injectors.

I ran across the Aeromitve setup which a nice package at a good price and I can get an extra discount on it right now. I haven't read or heard much about this setup and what people think of it.

https://rover.ebay.com/rover/0/0/0?m...2F264554324928

Alternatively I have been talking with Carl at Vaporworx about modifying a stock tank and using his adapter pieces to convert a 2010-2015 Camaro fuel pump to 60 psi mechanical regulation. The advantage to this is a GM fuel pump readily available anywhere; and the elimination of need to run a return line. Not a huge deal in the scheme of things but an added benefit. Pricing this out I could get it done for $50-70 more than the Aeromotive setup.

So, which way would you guys go?

Re: Fuel tank setup; experience and opinions please

The Aeromotive tank requires modifying the trunk pan to install it.

The top of the pump is mounted about the top of the tank. The tank is mount tight to the bottom of the trunk right where the pump is installed.

So trunk pan has to be raised in that area. You could raise and install an access door or panel.

I use the Tanks Inc set up. No trunk mod needed and the Walbro pumps are available at most auto parts stores.

What John said. I used the bevel corner tank from Tanks Inc. I also put in a hatch for convenience.

Re: Fuel tank setup; experience and opinions please

The fifth gen Camaro fuel module is the way to go imho. Reliable and works down to very low fuel levels due to the built in fuel bucket. There’s a reason why GM uses those pumps....

I wouldn’t use an Aeromotive setup if it was given to me. Seriously.....

Re: Fuel tank setup; experience and opinions please

The 5th Gen Pump is great but relatively expensive with the PWM controller etc. Last I added it up was about $2500.

The Tanks uses Walbro pumps which are the OEM pump on lots of cars and trucks. Cost is about $550.

I used this set op on LS2, LS3 and LS7 swaps and have not had any issues whatsoever.

Yes may be an issue if your are trying to run on very low fuel levels in hard turning situations. But who runs their tank down close to empty and is running spirited driving in the turns.

I know of a few Optima Challenge guys that run the Tanks Inc. without issues.

That said I need to get up to speed on PWM control.

Re: Fuel tank setup; experience and opinions please

Thanks for all the responses. Don, I think you've talked me into the 5th gen setup which I was leaning toward anyway. Had a bad experience with Aeromotive? I've never used their stuff so no first hand knowledge.

John I talked with Carl about PWM too. He also sells the controller so it can be done, but its overkill for what I have. If you get his regulator adapter and regulator you can convert it to mechanical control and nix the PWM. That's what I'm thinking of doing. If I'm careful on purchasing components I'll be right around the price of the Tanks kit, and can save the extra in not running the return and corvette fuel filter/regulator. Both are good options but just the way I'm leaning.

Thanks for the feedback. A lot of times it helps just to talk things out.

I too talked to Carl and did exactly what you are doing - couple of pics in my build thread. I bought a factory pump through Summit, already had a brand new factory tank and purchased the insert, retaining ring and regulator from Vaporworx. I think all in I am about $900.00. Wiring is simple and should work well.

Hey Matt, Why aren't you looking at the Spectra? It's the tank I'm running and I love it. I'm running the fuel injection tank even though I have a carb because I wanted the in tank pump. It's performed flawlessly.

Re: Fuel tank setup; experience and opinions please

This is what I am using. It might not be right for you, but it is an example of
one of the options available.

Ricks restomod tank 15091 $384 includes straps, fuel module locking ring and gas cap. No mods to your car. Bolts right up. 18 gallons.
Gas tank fuel level sending unit 10090 $109 Tube style, or you can use the one on the fuel module. Tube style is supposed to be accurate.
Fuel Module AC Delco MU2101 $210 (Camaro ZL1 fuel pump, includes O rings) No need for an external fuel filter.
Vapor Worx PWM controller 443.35

Total: $1146.35 The prices includes shipping to my house.

A bit overkill now, but if you increase the power of the engine, the fuel system is ready needing no future modifications.

The Vapor Worx website is very frustrating. There is a lot of general theory but nothing specific how the controller works. If you talk to Carl about what type of control algorithms are used, he gets very quiet. The instructions are very good that come with the unit. They are not on the website. The quality of the wiring far exceeds my AAW wiring harness.

Those tanks were notorious for starvation issues when cornering etc. You will never see it in a carbureted application like yours. The fuel bowls are like little surge tanks.

I'm not following you Don. "Surge tanks"? First time I've heard about starvation issues with my particular tank. Why would you never see it with a carb? It's a nice tank, baffled, with an internal fuel pump. All it needs for a carb is a regulator with a return. It's been working very well for over a year.

The fuel bowls serve as fuel buffers to carry through periods of fuel pump starvation.

Surge tanks were commonly used in EFI fuel systems to deal with fuel pump starvation during cornering etc.

Spectra may have resolved their issue. My point is a carbureted application is not sufficient to determine if that is the case.

I am not dissing your tank, I am sure it is fine for a carbureted application. I am just not convinced it would be a wise choice for an EFI application based on your application. Data from EFI applications is needed.

The baffles I saw in their tanks looked like little baking pans and really weren’t effective at all. And yes, I had one.

I suspect any fuel starvation issues you may have had were from an early model tank. The baffles are full size in my tank and in any new ones I'm sure. Here's a pic. I'll leave it at that for Matt's thread.

Re: Fuel tank setup; experience and opinions please

A little light reading for those who are interested. It seems Spectra does donuts in the snow to test their tanks.

https://www.camaros.net/forums/56-pr...any-fixes.html

Sorry to be a butthead but once a company burns me with poor engineering I am reluctant to trust them again without real data.
