i'm considering buying another 93(d250,auto,3. 54 lsd, ccab). the truck is really clean 2nd owner with 229,000 miles. what worries me is a fuel leak at the injection pump- it leaks (good drip) right at the front by the gear housing. there is a line(metal) coming from what appears to be a solenoid visable on lh lower pump going up between the pump and gear housing and entering a banjo style bolt on top(not very visable). appears to be the line leaking. how hard is this to get and change. it probably won't stop me from buying but i'd like an idea of what i'm in for
