Hi there,

I am sure there is a good site out there somewhere that can illustrate what I am looking to do. I have searched all over the internet and haven't come up with exactly what I am looking for. When I did the LS1 swap on my 76 Trans Am I used a Vetteworks adapter to put in my stock tank. I am hoping to either use that company again as I see they have an adapter for the 5th gen pump, but want to see how others have installed them. Does anyone have a build with pictures??

Thanks,
Ryan

Here is a thread with more info:

This was made by JCG Customs using Vaporworx parts, but unfortunately they decided not to make more of them.

Hi Clint,

Thanks for the quick reply. I probably should have said it in my first post, but I am hoping to do more of a budget swap, and weld a ring/adapter to my stock tank using a 5th gen pump. That is exactly the concept that I was thinking though. I was hoping that someone had a step by step putting one on their stock tank.

Have you gone to http://www.vaporworx.com and looked at retroworx kit tab (on left)? I know Ricks is selling a first gen style steel (stamped) tank that is ready to go. I went for the bling and got the stainless version of the vaporworx tank. I would contact Carl Casanova (owner of Vaporware) and see if he could help you out. He is a great guy and very helpful.

Do you have a particular reason you're wanting a 5th module?

The reason I want to use the 5th gen module is they are known to fit my application. I want to stick with a stock GM module for the ease of service and function. I used a 99-02 F-body fuel pump when I did my 76 Trans Am and it worked flawlessly. I want that same type of reliability. If there is another vehicle or pump that works the same I am open to the ideas.

This is my write-up I did for my 76 Trans Am fuel pump install.

Any help? I see the 5th gen pump uses a voltage regulator, does anyone know a way around this? Can it be converted to a venturi type assembly such as the 99-02 LS1 pumps?

If you're wanting to use a fifth gen pump you're gong to need a pwm unit like a vaporworx to control it. You can pick up a ricks retomod tank for about 375 which is already setup for it.

I'm still researching but is the pwm absolutely necessary? Looks like on this site they are saying it's not necessary. Look at post 6

The 5th-gen LS3 fuel module can be converted to a mechanical 60psi constant pressure output when a VaporWorx fuel pressure regulator adapter is used with a 4th-gen pressure regulator. These components replace the OEM safety valve that is in the 5th gen module.

Also available from VaporWorx are the proper Delphi sealed connector, components, and wiring to be able to make it a clean installation.

When done in the above manner the system is a single line to the fuel rail set up. No not truly returnless, as that can only be done with pulse width modulation control, it's about as close as can be using the traditional style set up.

Due to the high power requirements of the ZL1 and CTS-V fuel modules, pulse width modulation control systems are highly recommended. VaporWorks has stand-alone pulse width modulation controllers for this purpose that can work in either constant or manifold referenced pressure modes.

It is not recommended to use the 5th gen fuel modules in a traditional return type system. If a traditional return type system is used the return must go back into the module reservoir. Under some circumstances the module reservoir will run dry if used in a traditional return system where the return line does not go back to the module reservoir.

Feel free to ask any questions or contact me at carlc@vaporworx.com

Man. You gotta love answers that detailed and definitive. Way to go Carl

I did my own install with a connector and regulator adapter from Carl plus the help of a machinist friend and a welder buddy. I also added internal corner pickups to the tank, and used the por15 fuel tank coating to ensure no missed pinholes or corrosion issues where the welding was done. The 5th gen module works awesome in these tanks.

Thanks ROMB-951 for the pictures of your conversion. I'm about to bite the bullet on this setup to get rid of the problems I've had with my 66 GTO Spectre tank setup.

Thanks for posting the pictures ROMB-951. Between your pictures and Carl's technical answers, this is exactly the information that I have been looking for. Once I get all the parts together, I will be doing my own swap and will put together a full write-up for it all. Thanks LS1tech!

I guess I just don't get it. You said you want OEM reliability, but then you're modifying the OEM part and controlling it in a way it wasn't designed for which may or may not affect all that.

IMO if you're going to use a 5th gen module and want OEM reliability, you should leave it alone and control it with PWM. If you don't care about all that, just get one of the tanks inc efi tanks which are like $400 with a pump included.

Then again, I'm far from an expert.

Blue89Bird,

I am not looking to re-engineer what GM has done. The only modification that is being done to the fuel pump assembly is converting the pump to run constant rather than the PWM. This modification has been extensively researched by Vaporworx, so I trust the source.

I just picked up the fuel pump assembly from a wrecked 2011 SS Camaro and looking forward to starting the mods for my fuel tank.

robm,

Please don't take it the wrong way, but the only part that your fuel filter is filtering is the rubber hose and external fittings. The fuel module already has an OE-quality filter element. It is the only one in the 5th-gen.

If PTFE flex lines are used are used with stainless hardline (or just a run of PTFE hose) no other filters are needed. Just flush the line before final connection to the rail.

What depth is required to use a stock 4thgen Fbody pump in a tank?

ryeguy2006a

iTrader: (27)

I can't remember exactly, but off the top of my head I believe it was something like 9" compressed and 11" fully expanded.
