Anyone seen black "goo" build up on their injectors from E85?

[QUOTE="MalcolmV8, post: 15205309, member: 8854"] Walbro. It's been a while but I think it's F90000267. It's rated 450 lph and is E85 compatible. it's commonly referred to as the 465 or 455 pumps depending who you ask. Update: I had the injectors flow bench tested and cleaned. The shop said they were a little dirty but not bad. True it had that black stuff on it and was kind of nasty looking but the flow was still pretty good. I then put them in an ultra sonic cleaner to completely and thoroughly clean them out as well. The car now idles almost 1 A/F point richer in open loop so the injectors are definitely moving a little more fuel than before. However it did not cure the original problem that prompted me to remove them. So while they were dirty it was not causing me any real issues. Based on this I'd think simply tossing a bottle of injector cleaner in two to three times a year should be plenty to keep them clean. [/QUOTE]
