Ford Motor Co. will recall the first 1,475,000 cars and light trucks it built in North America in the 1978 model year to correct an emission defect, the company confirmed yesterday.

A valve in the emissions control system might become disengaged and release gasoline fumes into the air, the company said.

Donald A. Jensen, director of automotive emissions and fuel economy, confirmed a report by the bimonthly trade publication. Ward's Engine Update. He said owners would be notified of the recall later this month.

Other recent recalls involve extension cord adapters sold with electric hedge trimmers, women's sweat shirts, and grape jelly.

Ford spokesman Chuck Gumushian said the California Air Resources Board first noticed the fumes problem last November. Ford investigated and made assembly line changes in mid-February, he said.

Gumushian said it tool until now to track down which plants installed the defective valve.

The spokesman said the recall was voluntary, but Ford had notified the U.S. Envioronmental Protection Agency of its plans.

Gumushian sais the recall covers all 1978-model cars and light trucks built in the U.S. before the February change was made.

It was Ford's 21st recall campaign of 1978, bringing the total number of Ford vehicles recalled this year to about 5.5 million, Ward's said. Gumushian said he didn't know whether that figure was accurate.

Ford estimated that only 200,000 of the nearly 1.5 million cars would have the problem, but the company was unable to pinpoint which assembly plants installed the defective valves and decided to recall all the models Gumushian said.

The Consumer Product Satety Commission announced the recall of extension cord adapters sold with Black and Deck electric hedge trimmers yesterday.

The agency said about 1,000 out of more than 200,000 such adapters marketed this spring and summer may have exposed brass electrical contacts which could pose a shock hazard.

"Consumers should immediately stop using the adapters and closely examine them for any metal showing through the outside surface. Adapters showing metal should be returned for free replacement to any Black and Decker service center, or a Black and Decker in the Yellow pages," the agency said.

It added that the adapters "are orange and can be identified by the number '86-210' molded on the outside surface. The adapters are supplied as standard equipment with hedge trimmers along with instructions for attaching the adapter to an extension cord."

The company is conducting the recall voluntarily and is sending recall instructions to all consumers who mailed in registration cards packed with the hedge trimmers.

The commission also announced the recall of 30,000 women's sweat shirts which may not meet federal flammability rules.

Involved are long-sleeved, 100-percent-napped cotton shirts which can be identified by the number RN34104 and the words "Made in Hong Kong" on the label. The hand tags which came whit the garments carried the style numbers 502, 506, 507, 509, 619, 620, 621, 623 and 624.

The recall is being conducted by Huk-A-Poo Sportswear Inc. of New York.

"Consumers who have purchased these garments can return them to the place of purchase for payment or credit," the CPSC said.

The Food and Drug Administration announced the recall of 180,000 individual servings of McDonald's Grape Jelly that pack a wallop.

The one-half-ounce cups accidentally were made "with a hot peper-like substance used in taco sauce," the agency said.

The grape jelly, in 450 cases with the date JUN 6 78 stamped on the outside, was distributed to the hamburger chain's outlets in Texas, Oklahoma, Arkansas and New Mexico.

They were made by Han-Dee Pak West of Dallas, which also makes taco sauce. McDonald's began the recall on June 26, thed FDA said.

The agency also said the mishap was not likely to harm anybody.
