I second that. Two poorly designed custom "upgraded fuel systems" cost me two engine rebuilds when the engines detonated during races.

Thanks guys. I can't relay enough how many of the aftermarket fuel systems out there are fundamentally flawed by design, and create nothing but potential problems. The fact is, it costs many thousands of dollars and a lot of work to properly design a fuel system that is safe in all instances. Virtually nobody goes through the hassle, as it is a very difficult process to both sell, and market in any fashion. The "simple" routes are often taken because they are easy to market, and the results can be quite dangerous for your engine in the long run. A fuel system without an active
dual-stage surge canister will have unreliable fueling, and a standard return style fuel system on a Viper is begging for 150* fuel temperatures, vapor lock, and fuel boiling in the tank making fueling again unreliable at lower levels. Contrary to popular practice, you cant just replace the OEM pump with an aftermarket pump or two [ignoring the fuel line size issue as well] and still retain surge canister function, as all aftermarket drop-in pumps are single stage, not dual. Also on the same topic, you cant drop pumps in without a surge canister at all, and expect reliable fueling. Just because you may not have a frequent total loss of pressure, does not mean you aren't pumping air through your injectors on a regular basis at lower levels. The Viper, particularly the SRT, has a relatively flat and wide fuel tank--- just about the worst combinatoin for a surge-less pump system.
All that being said, there is absolutely nothing wrong with the OEM fuel system provided it has adequate flow for your application... and I have yet to see any N/A car make more power than the OE fuel system can handle with the correct injectors for the application. It is one thing to put in a "standard" fuel system that has some negatives because you absolutely need the flow, and are not willing to shell out big bucks for a complete revision... but to put one in when you don't actually need it is literally paying extra money to gain a list of problems.
