Fuel tank construction

Thanks Traven.

I spent months engineering and testing the systems in 2009-10 before ever announcing their availability. There are parts out there that have recently come out that look AMAZINGLY like my recessed fuel tray that was built in 2009. Ditto with some other components. There are also some real engineering concerns in some of the other designs that are not addressed or even questioned by most users.

The information shared on http://www.vaporworx.com I believe is necessary in order to help understand the advantages and complexities of the modern fuel module and EFI requirements. There are $millons spent in GM R&D to make these things work. A Gen5 fuel module new is about $220. Yes it's double what a Walbro 255 is, but the overall capability of the GM fuel module is outstanding. It's really in a different universe. It also makes fabrication easier and fuel delivery better. Replacement parts are as close as your dealer. So the initial outlay of cash may be higher, but the overall cost in time and money makes it about even in the end but with a much more capable fuel delivery system.

There is another pwm system out there similar to mine. I've tested it as well. Let's just say that the results from the lab testing were such that there was no way I would put it in my car for further testing. I know what they had to do to make theirs compatible with a very wide variety of pumps. When one does that capability must be sacrificed, and the sacrifices made, IMO, make them incompatible with what our needs are. I took the other approach by narrowly focusing on the modules that work in our cars and then designed the control systems to make them work properly.

For used Gen5 pumps go to camaro5.com. I've bought three from there to use as test mules and they have been just fine. Usually they can be had for about $85 shipped.
