Velocity stack, 40mm
Improves air entry into the carburettor and will give a small increase in power. The gain depends on the state of tune of the engine. This stack is suitable for 40mm Dellorto and Weber carbs. Price is for one (1) stack.
Velocity stack, 44 to 45mm
As above but for Weber 44 IDFs or Dellorto 45 DRLAs. Price is for one (1) stack.
Facet fuel pump kit
Solid state electrical pump provides sufficient fuel for normally aspirated engines up to 160bhp. This kit comes complete with pump inlet and outlet fittings (including filter) and two rubber shock absorbing mounts which help reduce noise.
Competition fuel pump (kit)
Supplies 6.0 to 7.25 psi pressure, 35 gallons per hour. Suitable for engines producing up to 200bhp. Comes as a boxed kit - includes: pump, inlet and outlet fittings, filter and rubber shock absorbing mounts. Must be mounted near and below fuel tank. You must also run a fuel pressure regulator to reduce pressure to approx 3psi at the carbs. See below.
Fuel pressure regulator
The needles and seats in your Weber or Dellorto carbs are not designed to cope with more than 4psi fuel pressure, so when using a high output fuel pump, you'll need one of these to reduce pressure to the desired level. Adjustable between 1.5psi and 5psi.
Fuel line tee piece - 5mm steel
If your twin carb kit doesn't feature a twin fuel inlet on one of the carbs, you'll need a tee piece. On engines making 150bhp plus, it's also advisable to run a tee piece. Otherwise you're relying on one float bowl filling up before fuel will be sent to the other carb.
Fuel line tee piece - 7mm steel
As above but or 7mm hose.
