This setup now has fuel pumps in both "saddles" - with the main pump shown above. Pyrotect added flanges to the upper half and we added bolts to connect the upper and lower sections of the steel can. In May of 2020 (yes it took that long) this was returned to us converted - they cut the steel tank in half and now it is the "can" for the internal fuel cell bladder. In July 2019 we removed, cleaned, and boxed up this steel 2010 tank and sent it to Pyrotect Fuel Cells for conversion into an FIA fuel cell with ballistic bladder and internal surge tank. The STEEL saddle tank in earlier S197 (2005-2010) Mustangs is the same size and shape but it CAN be converted into a fuel cell and used in the stock location with minimal changes.
But it cannot be converted into a fuel cell. This design "crashes" well in crash tests. Most modern cars use an OEM plastic "saddle" style fuel tank, and the 2011-14 Mustangs use one like this. It fuel starves on long left hand turns, which I experienced when driving it at MSR Cresson also. On this 2010 Mustang GT "Spec Iron" car we were tasked with moving it up to NASA American Iron and ST2 classes. This example is more elaborate and expensive. We did this work on his car in Feb 2018 and Jamie ran this car soon after at MSR Cresson in MArch 2018 - with no more fuel starve issues.Įxample 2 - FIA Fuel Cell with Internal Surge Tank Any "overflow" of fuel in the surge tank returns to the stock fuel tank. The pump inside the surge tank is always covered in fuel and it feeds the engine. The way this works is the stock lift pump feeds fuel to the surge tank, which stays full. Again - we wanted to keep this as close to OEM as possible. Many "race car" fuel systems will utilize a feed and return line from the engine bay, with the regulator at the fuel rail of the engine. Like the OEM system, this feed line "dead heads" to the fuel rail on the engine, as it is regulated at the surge tank. The 3rd line is the high pressure feed line from the surge tank heading to the engine bay.
#Radium fuel system series#
These two lines (lift pump feed and overflow return) go from the tank (shown above) to a series of bulkhead fittings in the trunk floor. There is a return "overflow" line from the surge tank that dumps excess fuel back into the OEM fuel tank. The stock in-tank pump acts as a lift pump to feed the surge tank.
We then converted the stock fuel pump drop in module to use AN -6 braided lines and Fragola fittings. We started by unclipping the OEM plastic fuel lines and dropping the tank. We tried to minimize the modifications to this fairly stock drivetrain and fuel system. We kept the stock fuel pump in the stock fuel tank. On his car, which uses the OEM computer and wiring, we installed this Radium Engineering remote surge tank with an internal pump and built in fuel pressure regulator. It runs 315/30/18 Hoosiers at all four corners + has real aero, and would fuel starve under 1/2 tank in long left hand turns. We performed this solution on Jamie Beck's 2013 Mustang GT, which was prepped for NASA ST2 and ST3 competition.
#Radium fuel system update#
We will update this when we do the same to our current 2015 GT S550 Mustang build (which will use an external surge tank). We ran this car in a class where we needed ballast to make weight (we ran NASA TT3 class at 3802 pounds - to be able to get a bonus for higher weight in this power-to-weight class), so it wasn't an issue - unless we forgot to refuel for a session.īoth examples of the "fix" below are from different S197 race cars we built for customers.
#Radium fuel system full#
On our 2011 GT we just ran with the tank full for every Time Trial session, and we ran fairly short sessions. If you are timid (slow), or use really crappy tires, it might never happen to you. This won't happen on "every" left hand turn, and not to every driver. With big Hoosiers and/or aero grip added, it can happen on long turns at even 3/4 tank. We fought this on both our S197 and S550 road race cars, and with good 200TW tires fuel starvation happens at 1/2 tank or less. There are two solutions we have used to "fix" the common fuel starve issue on the S197 Mustang, which occurs on long left hand turns on a road course as grip levels go up.
