* Harbor distillates dip on high inventories * Fire at PBF plant had little impact on output- sources * Gulf Coast ULSD pares Monday gain * Chicago distillates rebound following sell-off NEW YORK, March 20 (Reuters) - Distillates traded lower in the New York Harbor on Tuesday due to growing supplies of heating oil, ultra-low sulfur diesel (ULSD) and jet fuel. Sources said a fire at PBF's Delaware city refinery did not affect output which further weighed on the market. Prompt and any-March heating oil were pegged at 2.50/2.00 cents per gallon under the April heating oil futures contract on the New York Mercantile Exchange (NYMEX), down 0.75 cent on the day. Prompt and any-March ULSD were talked at 7.50/8.00 cents over, down a quarter cent from eight-month highs. Prompt and any-March jet fuel were called 4.75/5.25 cents over, down 0.75 cent. Sources said the Friday fire which hit a desulfurization unit at PBF Energy's 182,000 barrels-per-day (bpd) Delaware City, Delaware, refinery took out one of the unit's trains but had little effect on operations. The warmer-than-normal winter heating season has led to growing stocks of distillate fuels in the region, which put pressure on cash markets, traders said. Harbor gasoline trade ratcheted up as buyers filled end-of-season winter-grade demand before April trade rolls around next month, traders said. Prompt F4 RBOB was talked at 18.25/17.75 cents under the April RBOB futures contract on the New York Mercantile Exchange, up a cent a gallon, while prompt M4 conventional gasoline was called 15.25/14.75 cents under, up 2.00 cents. On the Gulf Coast, ULSD differentials slipped a penny per gallon to 5.00 cents over April heating oil futures on the NYMEX. The slip pared a late-day gain of the same amount on Monday's news that Valero Energy Corp would shut its 235,000 barrel-per-day (bpd) refinery in Aruba by the end of March because of poor margins. Gulf jet fuel climbed half a cent per gallon to 2.50 cents over April heating oil futures on Tuesday as its latest five-day lifting cycle scheduled to move on the Colonial Pipeline. Conventional summer-grade M2 gasoline differentials also gained half a cent per gallon with deals seen at 15.50 and 15.25 cents under April RBOB futures on the NYMEX as traders focused on a new five-day lifting cycle. In the Midwest, Chicago ultra-low sulfur diesel rose 1.50 cents a gallon to 17.00/15.00 cents under futures, rebounding from its 7.50-cents dip on Monday that was triggered by a sell off at major trading houses. Group Three ULSD held to its Monday gains at 2.25/2.75 cents over April futures.
