The Chrysler arm of DaimlerChrysler said that it had recalled 464,315 of its 2001 and 2002 PT Cruisers to install a secondary seal to a fuel pump.

It follows the discovery of a fuel leak following a government crash test.

Chrysler said it knew of no incidents of, or complaints about, the fuel leak problem but was recalling the cars to reduce the possibility of a leak in a severe collision.

About a quarter of the same vehicles will also be recalled for a separate safety issue involving the fuel supply line.

Chrysler said the fuel line could rub against the air conditioning service port, which could result in a fuel leak.

Chrysler said it would attach a clip to the fuel line to prevent contact.

DaimlerChrysler shares were down 19 cents at $43.31 on the New York Stock Exchange in early afternoon trading.
