20-0967-03 PIK PLUMBING, GALLARDO LP VEHICLE COMPATIBILITY08-13 Lamborghini Gallardo LP550-2 (all trims)08-13 Lamborghini Gallardo LP560-4 (all trims)08-13 Lamborghini Gallardo LP570-4 (all trims)NOTE: Not compatible with the Audi R8 or Lamborghini Huracan. This kit permits an independant port injection fuel system. PTFE hoses, -AN adapter fittings, 1: 1 pressure regulator, pressure gauge, and a fuel filter (stainless -03 or microglass -05) are all provided. These components mount to the LH side of the engine using OEM threaded bosses on the frame rail. No drilling or permanent modifications are required. The Radium Engineering fuel hanger surge tank is recommended to feed this system. The regulator features the first tool-less pressure adjustment. A jam nut and set screw are no longer required. With a simple turn of the knob, pressure will be increased or decreased.  To aid in adjusting pressure, there are incremental detents that provide haptic feedback to the user. Every detent permits 1psi (+/-0.5psi) of adjustment depending on current fuel pressure. Furthermore, RA-series regulators feature a 360 degree swiveling vacuum reference port that is double O-ring sealed. This is the first in the industry. It permits the installer to quickly point the vacuum fitting in any direction with no tools required. There are 4 interchangeable 10-32 threaded vacuum port fittings provided to cover all scenarios. 1. Barbed Fitting: A black zinc-plated 3/16" (5mm) barb machined from high strength steel that is compatible with the following vacuum hoses: 5/32" (4mm), 3/16" (5mm), and 7/32" (6mm).2. 3AN Male Fitting: A black zinc-plated adapter machined from high strength steel that is compatible with 3AN hose ends.3. Push-To-Connect: A nickel-plated brass fitting with Buna-N O-rings that is compatible with hard plastic 1/4" OD tubing.4. Vacuum Plug: A black oxide stainless steel screw that is used to maintain a constant (non dynamic) fuel pressure. To keep fuel pressure the same as the OEM fuel system, this plug should be used. This kit is suitable with all gasoline types including unleaded, leaded, oxygenated, and pre-mixes. Furthermore, they are compatible with alcohol blends of fuel including methanol, ethanol, and E85.
