@dmta As far as the line order goes: The large line from the petcock goes to the fuel filter, the other side of the filter connects to the left side inlet of the fuel pump. The right side (large) connector on the fuel pump connects to the carbs at the center inlet. One small line connects the left inlet on the engine block to the petcock and the other small line connects the right (toward center) inlet to the small inlet on the fuel pump. (The two small lines provide the pnumatic operation)
@g36cLover No problem, I just didn't want anyone that's never opened one up before to get confused and think they fixed a fuel pump when it's a different part. I can see how it would get mixed up though as the inside diaphragms look almost the same.
@dmta Here's how to check if your petcock is ok. Put the fuel switch to the "on" position, take the bigger of the two lines off of the petcock, take the smaller line off of the engine block, but leave it on the petcock. Fuel should not flow, if it does, your petcock is broken. If not, gently apply some suction on the small line, fuel should flow from the big line's socket on the petcock, but none should come out of the smal line. If any one of these conditions are not true, the petcock is bad.
Uh, I hate to break it to ya, but that's not a fuel pump on the backside of that petcock that you refer to. That's simply the vacuum controlled valve. The fuel pump is further down the line, behind the fuel filter. It is a pulse operated pump and is bolted to a bracket connected to the frame of the SECA II.
This video was very helpful! I have 1996 Suzuki GSXR 1100 and I have a petcock repair kit. Is it necessary to use silicon when replacing or does that just apply for your particular motorcycle?
why would you not remove the fuel diverter before you put the unit in the carb cleaner? there may be some trash behind it and will hamper the life of the rebuild, there is a new one in the kit? Im confused
I just bought a yamaha xj, and my petcock is leaking from the front. Can I replace the front gasket without taking off the rear section? I'm too lazy to remove the entire valve.
Thanks! this was great; I'm currently rebuilding my 1992 Seca II Petcock for the first time.
One of the best instructional bike vids on yt! Tks!

@holiwoodpa1 Silicon is not necessary, I use it to keep everything soft while I assemble.
@draco751 Yeah... that assumption was from another bike I did years ago, I discovered it was just a valve after I put it back on.

What's the goop in the yellow can? Can't read the label or quite understand the audio when you mention it.
Since all three cans are somewhat yellow, from left to right:
Chem-Dip, Silicone Spray, Carburetor Cleaner
@@cameronford6645 It was the silicone spray! Thank you.
