Inlet Manifold Fittings - V8 Carbs

In order to select the correct parts, this section will help to identify the type of carbs fitted to your engine. It is for identification purposes only.

Carb Identification - Stromberg CD175 & SU HIF.
Both makes of carburettor have a silver tag - stamped with an identification number - which is attached to the carb by one of the dashpot retaining screws.
(Note; both rh & lh carbs have the same number but with an r or l suffix as appropriate). However, if the tag is missing, the engine number will help you to identify the carburettors, providing they have not been replaced by a previous owner. (For detailed information & specification of engine numbers, please refer to the V8 ENGINE section).

ROVER SD1
All Rover SD1 3500 saloons from 1976 to 1981 were equipped with a pair of SU HIF6 carburettors with a manual choke. The tag number on these carbs is FZX1316R (right hand carb) or FZX1316L (left hand).
From 1982 until 1985, SD1 3500 carb engines were fitted with Stromberg CD175 carbs, incorporating a FASD (Fully Automatic Starting Device) on the side of the left hand carb.
Easily identified by its blue plastic cover, the FASD is essentially a cold-start enrichment device.
Stromberg carbs have a stubby dashpot, compared to the SU’s taller version.
Finally, from 1985, the SUHIF6 was again fitted to some 3500 models. However, these were not the same carbs as the earlier ones, being considerably more complex in their coldstart enrichment operation. The tag numbers for these carbs are FZX1456R & L.

TR8
Original carb TR8s are fitted with a pair of Stromberg 175CDSET carbs, with an automatic choke.

RANGE ROVER
Two makes of carburettor are fitted to Range Rovers as standard equipment: the Zenith Stromberg CD175 - used exclusively from 1970 to 1986 - and the SU HIF, which was fitted for a short period (alongside the Stromberg) from 1986 until carbs were replaced by fuel injection.
The most obvious visual difference between the two types of carb is the dashpot; Strombergs having a stubby dashpot with the 'Zenith' name cast into it, while the SUs have a much taller dashpot without any markings.
