Correct me if I'm wrong. It seems that in all of the independent tests cited on the forums, biodiesel mixed with regular diesel gives the largest improvement in HFRR scores. Also the tests cited don't use 2 stroke oil at the 1 oz/gallon ratio. Biodiesel gives the best improvement and I think would be the least expensive additive.

Thanks for the replays. I know the leak is at the vacuum pump/power steering shaft seal is.

I followed the instructions to the letter and watched the video 2-3 times. I even had the video going and would pause and follow each step. I'm very OCD about doing things right. I even called Pete Gould and talked with him about questions I had. By the way he's a really great, friendly guy who's extremely helpful. I haven't talked to him about the leaks yet.

I have now replaced the seals in my vacuum pump twice and its still leaking. I got the kit from Gould Gear. The coupler drive gear has been replaced on the vacuum pump side and I bought a rebuilt PS pump which also has a new coupler drive. In theory that means there's a new surface for the seal to mount against. It shouldn't be leaking. I'm pissed and its driving me crazy. Any suggestions?
