Thanks for all of the tips, it has given me a lot of ideas about what the problem could be. As for water in the oil, when I bought the splitter, it didn't have a cap on it. I drained the tank and refilled it, but I'm sure I didn't get everything out of the lines, etc. so that makes sense that it could have water still in there. I'll try to get the model number for joetrausch to check out, or maybe it will have the GPM on the pump somewhere. I haven't had time (during the daylight) to look at it lately. I also owe you guys some pictures of this ugly thing /forums/images/graemlins/smile.gif
I was looking online at splitters from TSC and noticed that most of the larger ones had 5-8 gallon resevoirs on them so I'm pretty sure I'm way undersized there. Still trying to find a low cost solution to a bigger tank. I was thinking of a new air compressor tank. I'd probably have to weld some fittings on it though. When you consider the time involved, I might just break down and buy a new resevoir from Northern. I looked at the stuff the other day online. Looks like I could get a new 10 gal tank, filter, and a strainer for a little over $100 plus shipping. Not bad I guess, I'd still have less than $400 in the whole thing. Can't touch a new one for that /forums/images/graemlins/smile.gif
