91 300D with 100,000 miles. Leaking fuel from the top of the injection pump....appears to be coming out at the base of at least one of the knurled nuts.

I'll have my indie deal with this. Should I just go ahead and replace all five or is this one of those things where it's wise to save some money and only replace the ones that are leaking?

Thanks.

Think it's probably false economy just to replace 1- you might as well do all 5 while you're in there and it's apart- and it may not only be one leaking plus another one might spring a leak a few days later... parts cost will be low, as it's just crush washers and o-rings, the labour will be the main expense if you're not doing it yourself.
