I think those hoses might go to the evaporator canisters on the california model to route fumes through the carbon in the canisters. I don't think you need to worry about hooking them back up. Just follow them and if they go to two black soda can looking canisters that's prob what it is.

I believe that's part of the evap system, I don't think you need it. Put it aside and keep going.

86' 1200. Got new carbs and was putting them on when I got stumped by whatever this is. What is it, is it important, and how does it go back on?
I took it off my old carbs but I can't remember for the life of me how it went together. It's an 86' Cali

86' 1200. I just got new carbs and I noticed they don't have a spot for 2 hoses that were on my old carbs. Can I run with the hoses not connected to anything?

Got it ... thanks!

Ok that makes sense. So then he's got a trip to the plumbing isle to make his own reducer.

Well I checked my FJ today and I have the same RPM fuel line from tank fuel valve to stock fuel filter to fuel pump to golan 10 micron filter to my carbs. No reducer anywhere. My tank is a 1990 tank so not sure if that makes a difference? I do remember having some difficulty putting the fuel line on in one area, possibly the first fuel filter? but I think I just put some grease on the nipple and used some muscle to get it on.

I agree with Pat spend the money on the fuel filter from RPM so you don't have to worry about it and just enjoy your ride. If you buy a cheap one you'll be regretting "saving" that $150 when you're stuck 50 miles from home late in the afternoon.

"Yamalube Ringfree PLUS fuel additive" is the best IMO I use it with every tankful
