The FBI is investigating the possibility that union boss Jimmy Hoffa’s body is buried in a former landfill in Jersey City under the Pulaski Skyway, a report said.

The search was sparked after a tip passed down from a worker who said he buried Hoffa in a steel drum just outside the former PJP Landfill, now Skyway Park, the New York Times said.

An FBI spokesperson confirmed to The Post that agents had conducted a “site survey” under the Skyway last month after obtaining a search warrant, but wouldn’t say if the search had anything to do with Hoffa, the mob-connected Teamsters leader whose July 30, 1975, disappearance has become the stuff of legend.

“On October 25th & 26th, FBI personnel from the Newark and Detroit field offices completed the survey and that data is currently being analyzed,” Special Agent Mara Schneider said in a statement. “Because the affidavit in support of the search warrant was sealed by the court, we are unable to provide any additional information.”

The site and tip was the focus of a “Fox Nation” report earlier this year, with radar experts in the special saying they had confirmed steel drums at the site where Hoffa had ended up.

Journalist Dan Moldea, who has written extensively about Hoffa, passed the tip on to the FBI, according to the Times. This latest tip originated from PJP worker Paul Cappola Sr., who later told his son that he was pointed to a specific spot to bury the body by landfill co-owner Phil Moscato.

Cappola told his son in 2008 that he grew nervous about someone having potentially seen where Moscato pointed, so Cappola picked a different area of the dump, the Times said. He used an excavator to bury the drum and several other drums eight feet or more under the ground, covered with stones, dirt and “something detectable” under the surface, the Times said.

Cappola’s son, Frank, died last year and passed the tip to Moldea, the Times said. Moldea discussed the report on Twitter Thursday.

“For me, this has been a long 46-year journey,” he wrote. “I have full confidence in what the FBI is doing. I don’t want to say anything that will jeopardize their investigation. Once resolved — win, lose, or draw — I will have much more to say.”

Hoffa’s disappearance outside the Machus Red Fox Restaurant in Bloomfield Township, Michigan, has led investigators on searches all over the country. Earlier this year, a former mob lawyer claimed he’d helped bury Hoffa’s remains at a Georgia golf course.

The 2019 film “The Irishman” depicted Frank Sheeran killing Hoffa in Michigan, with his body later incinerated in a scenario that many experts believe is unlikely. Authorities have been pointed to New Jersey before, though, the Times noted, and Sheeran was supposedly meeting New Jersey mob boss Anthony “Tony Pro” Provenzano and another Mafia leader on the day he disappeared.
