breva 1100 oil pressure sensor

[Neil]

Hello,
         If you've ever replaced the oil pressure sensor, what tool did you use to tighten it? I've found nothing so far that fits. It's a 15/16" (24mm)  wrench, but any wrench with that opening is designed for much higher torques. I'm considering making something out of flat scrap. I reall;y don't want to drop the engine  TIA.

Hello,
         If you've ever replaced the oil pressure sensor, what tool did you use to tighten it? I've found nothing so far that fits.

Some say if you remove the left exhaust header that you can get in to the sensor. My hands are too fat for that.

Generally involves removing the tank and air box and it's super easy to get to with a socket and ratchet. If it's cool where you are, a blow dryer on the rubber boots that connect the air box to the throttle bodies can make them more pliable. It's a bit of a game of twister and Jenga combined to try and get the air box in and out but it's really not that hard if you take your time.

It's also a great time to change your air filter and fuel filter especially if it's the half plastic half metal type.

Perhaps the most difficult part is getting the fuel line off the barb on the fuel tank.

For whatever reason I've not had much trouble with it but many do. Here's what I do.

1. Grab the fuel line just behind the connector firmly and push and pull back and forth on the barb to loosen it up a bit.
2. With your middle ring and pinky finger squeeze the fuel line behind the connector ring as tight as you can and push it towards the fuel barb.
3. While pressing it forward as described above, use your thumb and index finger to squeeze the ring and pull it towards your other fingers in other words down and away from the fuel barb.
4. With the fuel ring pulled down speaking moving the fuel line back and forth It should come loose on the first or second tug.

That's at least my unsolicited advice for how I get The fuel line off without much drama or problems. In fact I didn't know it was a problem until I started reading about it.

All that sounds pretty damn right.

You might want to double check the size of the sender. If it's a Guzzi one not automotive aftermarket, IIRR it's 21mm, at least for most models.

Quite true.  I went thru a few sizes and settled on one from NAPA forabt $16.00 that had a 22mm head to reach in an tighten after the tanks and airbox was removed but not the alternator.

        Success, to a point. I was able to get a wrench in and tighten it down, now it's a case of remembering where all the hoses go. I should have written in the opening post, that I removed the gas tank and airbox and the left side exhaust header. I was able to use channel-locks to loosen the old sensor. The reason for replacement was that it was leaking oil. The new one is the same diameter across the flats as the old one, which was a BMW part that the local dealer installed after not being able to source a factory replacement , back in 2014. 
        What part were you able to substitute for the sensor? I tried all the auto part chains, NAPA and one of the others listed a part but couldn't order it through their normal distribution process. Supposedly, it's the same sensor for a  1980's BMW car.

I replace them with the nail head ones & make a jumper wire, it's the most reliable

           There's a tube sticking down from the left rear corner of the air box. Is this the aperture for the drain hose? I think the hose may have dry-rotted and fallen off. I don't remember taking a hose off that area of the box.  There was a short rubber collar on it when I went to start the re-installation process.

Yes.
