I should get my injectors back from eatont9999 this week. He said they were the dirtiest injectors he'd ever seen!
He pop tested them before disassembly and apparently they all leaked under pressure and the spray pattern was more like a garden hose...
In the mean time I replaced both fuel filters. There seems to be an awful lot of rust in my in-line filter. (photo attached) Is that pretty much par for the course on a 40 year old car, or is this indicative of issues in my fuel tank?
