3803964 Injector | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta injector for Stage 1 and Tier 1 engines, weighing 0.204 kg and listed for three applications across the TD and TAD series. The reman catalogue carries this number in its injector table against TAD420VE, with TD420VE taking 3803955 - so the engine designation and the emissions stage are the deciding details. 3803968 at 0.206 kg and 3803955 at 0.206 kg are within two grams of it, so weight is no help. Supplied on exchange: core deposit 3806964 is charged alongside it and refunded once the old injector is returned.
