Perkins 6-3544 fuel leak

I have noticed a fuel leak at the top of the injector pump. It is where the fuel tubing (the one that goes to one of the injectors) attaches to the pump. It seems very tight already so am afraid to try to tighten it further. It has a fairly regular drip.. Any suggestions? Any one with similar problems.. Is it a compression fitting or something special?. Thanks cliff

If your sure that’s where it’s leaking , loosen the nut and make sure the line seats properly and doesn’t have a crack . I just replaced my Injection pump and two of the lines didn’t seat just right . I had to tweak the lines a little to make them nest just right . They need to nest in their pocket before tightening the nut .

Try loosening it a little to let any debris that may be stuck in there escape, then re-tighten. If you do that while it's running, put a rag over the joint cause there will be some pressure.
Those pines have what Perkins calls an "olive" formed into the line. Basically a compression fitting.

It could also be cracked in which case you'll need a new line.

Hope the first thing solves it.

Edit
Sorry "Pack Mule" didn't see your reply while I was writing mine.

When you sung down the fitting use a flare wrench. You avoid any rounding of the fitting nut.

Will call trans Atlantic and order a new fuel line for that cylinder. I tried loosening it and tighten again with the same outcome. Slow drip...when I tighten it down the wrench sort of stops..not a nice compression if you know what I mean..Ian afraid that I will break something if I do it tighter. Thanks for your help..

+1 on the flare wrench. Typically $11 for a set of three.
