Both Petcock Screens are torn, any suggestions?

93 VN750
I had a leak from the petcock so I removed it. I found that both the screens were ripped. Any ideas how to fix this?

The leak was just a bad gasket. No Problem..

Best thing to do is get a petcock repair kit off of eBay. Probably not a bad idea to replace everything in there anyway.

You could probably buy a new single line, non vacuum petcock for less than the repair kit. I believe the petcock off a 97 Yamaha Trailway works... it's somewhere in the forums. I'd be curious to see if a petcock from a new bike would be more resistant to the ethanol that kills ours. The new rubbers are supposed to tolerate it.

If it ain't broke... well I'm sure I can find something that is

I wasn't able to find a rebuild kit with screens. It's good to know you can find them.

I ended up buying a used pc from an older year. Actually has the 'pri' positon. It was in decent shape so I didn't need to rebuild it... this season anyway

If you can't find the screens you can try searching the forums for petcock and you'll find the post with the one from a Yamaha that is pretty cheap. Although it will work, knifemaker said that it really wasn't a good replacement because of the way the outlet was positioned. It is a single outlet and so it would have to be tee'd, and if you ride aggressively I don't know if the feed will keep up. You might find the engine starves at high speed.

Thanks for the replys everyone. What I was hoping for are ideas on where I could get the screen material and then wrap the 2 posts with it. I'm talking about possibly buying something and then tearing it apart to get the screen material.
Of course I've read posts about putting an inline filter in, but I just feel that their must be a better way.

I tried replacing screen on my original pc with varulious materials and trust me man... it is so not worth it.

Single line petcocks have been reported to feed plenty of fuel. It's only a single port (and then the reserve port, which is usually closed) from the tank to the two taps. The port is smaller than either tap. Installing a single line petcock just makes the T visible. It also does make a bit more spaghetti, but it certainly works.

I should have a spare tap somewhere with a good screen, but as I recall they are press fit plastic pieces... and probably quite brittle after years of sitting in gasoline. Probably better off putting good guts in a tap with a good screen.

You could also try soldering a fine brass mesh over the torn section of screen. I resoldered part of my oil screen because it was separating at the seam, but there was also no plastic there. If you have the old style tap with the straight pipe and a small screen at the top, you might also be able to fit a brass filter element over the top of it.

Filters are nice, but a steel tank will drop rust which eats away at the seals in the tap. If you want to do away with the screen, consider coating the inside of the tank.

If it ain't broke... well I'm sure I can find something that is

Wish I had thought of that, but then again, I made a gorilla move of ripping the screens off thinking I could surely get replacement screen .

NOT!

I went to Kroger's (food store) and got a re-usable micro sceen coffee filter. Uh ... yea, I still have twitches from that attempt.

Then, I installed two of those nice glass fuel filters. They were a bit#$ to get in. Didn't work. I kept starving for fuel. Vapor locks and such.

I ended up paying additional stupid tax, and buying a nice new replacement.

Works like a charm, and a later ear shave will have plenty of fuel delivery.

Thanks everyone for your input. I'm not in a hurry to ride so think I'll keep looking around. Maybe do some searches on SS mesh and see if that leads anywhere.
