Pinholes in the Fuel Injector Rails?

Pinholes in the Fuel Injector Rails?
I took the fuel injector rail off my 1984 XJ6 4.2 FI in order to change the hoses. Prior to taking it off there was no evidence of fuel leak. I cleaned it up and when doing so I noticed what appear to be pin holes in the brazing/welding in 4 of the 6 Fuel Injector metal "T" where the Fuel Injector Barbed Connectors are. I got a sewing needle to see if the holes went all the way through and they seem not to. Almost like there was a bubble in the metal when it was welded/brazed or whatever,
My question is has anyone ever noticed this phenomenon? I would have thought that with that number of pinholes (if they really are "holes") I would have had gas all over the engine compartment. I attached pictures of two of the bigger holes. The pin shown does not appear to go all the way through.

Yes, probably nothing to worry about, but ..... I'd order a replacement piece from David at everydayxj.com. Have him be sure to check and make sure the one he sends you looks solid. Or, at the very least I'd have an expert in brazing look at it.
While we are on the subject, I highly recommend that anyone that drives and old car, regardless of make or country of origin carry a fire extinguisher at all times. Experts say that if you think you might have a fire under the hood to not open the hood until you have a fire extinguisher at the ready. I keep mine in a black sleeve with foam rubber so it won't roll around. I keep it in the footwell of the back seat right behind the driver's seat. It's like car insurance, you don't plan on needing it but, if you do need it, you sure better have it.
