fuel leak

[chessie 6.5]

Finally got the engine back together and running after down 4 years....looong story; anyway, the fuel injection pump is dripping fuel off what appears to be the head of a small bolt on bottom about 1 inch to rear of mounting flange of pump. Looks to have, maybe a 8mm head. I'm familiar with the old 6.2 pumps after repairing so many, but this one is unknown to me. Is there a drain hole to allow a bad shaft seal to leak out to avoid the fuel getting into the crankcase like the old style pumps. Any other ideas? I don't see any leaking elsewhere; used an inspection mirror to check. Thanks

There is a weephole dead center under in the mounting flange.The housing has a seal in it on either side of that hole.prob the origin of the drip.
The bolt head you mention there furter back holds the internal tranferpump in place.there is no washer or 0 ring on this bolt,if it worked loose it'll leak too.(unlikely)

thanks; sounds like the front and seals may be the same as the 6.2's used.
