Hi guys I am thinking on buying a kunkle valve for my setup does does any of you uses them on your systems? what are the good or the bad on them, are they worth it?

Also how hard is it to install? I saw them on Larry's site and other companies but I think Im going with the REP website since I need some oil and grease for my blower here is the link

I have a kunkle valve on my El Diablo. I also have a Hydramaster Salsa that just didn't seem to have that "great" vacuum I wanted..so we installed a kunkle valve and now have that great vacuum. Installation was pretty easy and kunkle valve was under $200 if I remember correctly.

I had a Kunkle Valve on my Fox 8500, and ended up switching back to oem. Reason being that performance was inconsistent. Sometimes would get stuck open and would not close. I had to lubricate that thing every day to prevent sticking. Also, I didn't like when it cracked open at 15", lift would drop to 12" and stay there until I stopped cleaning. What I would prefer is to have vacuum relief valve that would hold a constant 15" lift and not drop below that.

What's the deal with Bayco Valves? Anyone tried those?

I believe that wd-40 causes them to gather sticky residue from the oil in it.
I have had better luck with mine if I shoot a little carb and choke cleaner in it once a week.
Mine does not give me too much trouble and does a very good job of regulating vac.

So to install the kunkle valve do I need to buy anything extra? and just drill the hole in the tank and done or it there any special instructions that I need to follow?
