Stanadyne fuel treatment/lubricant

[Garagefull]

Last year I inherited an old IDI of another brand.it had been sitting in long-term storage for nearly 4 years. In that time I've put approximately 4000 miles on it. The injection pump was cranky from day one. Hard Smokey starts, poor acceleration etc. A local diesel tech suggested the stanadyne fuel treatment. I finally found a bottle locally last night at a local tractor supply store. This product truly does work.Within 15 miles I noticed the engine running much quieter, hard starts are gone, and certainly increased performance. The other half of that bottle is going in the 300 today. Just thought I would pass it along.
