Due to its design, this manifold offers up to 10 BHP over other 4 barrel manifold options at high mid-range, with
increased torque over a wide RPM range, especially from idle to mid-range.
It also offers excellent throttle response.
Due to its height, it may not offer sufficient under bonnet clearance where space is tight.
Select the correct air cleaner to ensure sufficient under bonnet clearance when suitable.
A spacer may also be required to allow clearance for the pancake filter and carb throttle linkages.
A thermostat housing, air cleaner and carb levelling plate (for 4x4 and certain other applications), are all
available separately (supplied if purchasing conversion kit).
Suitable for Holley & Edelbrock carbs.

Suitable for standard road use carburettor cars.
This fuel pump has solid-state control which allows the fuel pressure to be controlled via pulse-width modulation of the pump voltage.
This increases the life of the pump, allows a smaller and lighter device to be used, and reduces electrical load.
It doesn't have electrical contacts, bearings or diaphragms.
The pump is self priming meaning that fuel is supplied as soon as the ignition is turned on, so the engine will start faster at colder temps.
For best results mount the pump close to the fuel tank and below the liquid level.
12v Negative Earth.
1/8 NPTF thread.
It has a fuel height lift capacity of approx 100mm compared to the Facet Red Top (RB7259) which has a lift of 200mm - meaning that generally a 'cube' will need to be mounted near the fuel tank but a Red Top can be mounted in the bulkhead area.
The fuel flow rate is 2.0 litres/min as opposed to 2.9 litres/min for the Red Top.

This is a Malpassi Filter King units and it can be adjusted via the domed nut on the top.
It not only saves fuel by controlling the fuel pressure but also collects the fuel contamination without destroying the vehicles performance and reliability.
On tuned, competition or trial cars it smooths out the surging in the fuel so that the fuelpressure is more consistent improving the driveability and performance.

Note: The improved composite inlet manifold gasket was first introduced on engines from 1992 approx. onwards, but is often used as a sensible upgrade on earlier engines originally fitted with the tin item.  The composite gasket type end seals ERR7283 may in fact be used with either a tin or composite manifold gasket, but whichever the case they must be used with their matching ERR7282 clamps.
