billofdurham » The only filter Volvo put on that model was in the fuel tank on the fuel gauge sender unit. This filter had to be cleaned or renewed every 6,000 miles as part of the service. Although fairly easy to do it was usually neglected – ‘can’t see it, don’t do it syndrome’.
On my 240 there was an in-line plastic filter between the pump and the carb but this was put on by a garage to keep the carb free of sediment.
If the filter is partially blocked it could be the cause of your problem but also check:
- the piston/needle in the carb is not sticking;
- check the oil level in the carb dashpot is not too low;
- check the free play of the damper piston on its rod.

In the luggage compartment lift the carpet and you will see an inspection plate in the floor. Remove the plate to see the top of the sender unit. Disconnect the earth (ground) wire and the lead from the sender unit terminal. The sender unit is held in place by a locking ring which can be taken out with a special tool or by using a piece of hard plastic and a hammer. The plastic is to prevent sparks. Place it in one of the cut-outs in the ring and gently tap it until the ring comes loose. Lift the sender unit out of the tank. It is possible to make the tool if you want to.
The filter is on the very end of the unit. When replacing the sender you need a new gasket.

The Volvo 240 was made from 1983 to 1993. For the 1983 model year, the rear emblem for all 240 models just said 240, when it had previously indicated 242, 244, 245. It was described as being part of a new designation strategy, but most people still referred to their cars as 244s or 245s.
