Lol well shit, I owe you one lol, what way would you do it racer?
I think most pwc guys do hook it up to the return line IIRC. Those primers can leak air sometimes around the shaft (in the sled world), not good to introduce air into the system. What I think would be trick is to put a small line inside the fuel baffle with a sintered filter (like the weighted ones on a string trimmer) on it and use some type of hose barb to connect to the outside of the baffle. That way you're not compromising any fuel delivery. But Braley would know best. Several ways to skin a cat.............

If you put it in any line, make sure it's at a 'low' spot in the line. Mines in the return line above the baffle and there's never any fuel in it to draw into the primer. Doh.

Put it on the reserve line. Any other line and you won't get any fuel. I put it in the return line in both my skis at first and never could get fuel.....unless it had been ran. Which defeats the purpose of a primer. Moved it to the reserve line and it works perfect. I've even run the ski on reserve with it t'ed in there and it runs fine.
It's all been covered above but I'll just recap. The primer draws fuel in the angled barb and spits it out through the straight barb. You can put a finger over those fittings to confirm. It will only draw in one and only spit air out of one while you hold it in your hand to test.
Those primers are crap now and can't be trusted. The old ones would last five years at least, now they spit gas at me while I'm pumping them in the first year sometimes. WFO noticed this a couple years ago and I saw it myself soon after. It might be ethanol but I think another Chinese company just got the contract that has lesser quality control. The racers have moved to these button primers http://www.ebay.com/itm/PRIMER-KIT-...ash=item2362e5139f:g:qVEAAOSwB4NWv8yY&vxp=mtr I've installed my first one in my black XPL and it works pretty good.
Since we know the traditional primer will fail you want to keep it off your supply line. If you run on the ON channel and only use the RES for emergencies then the RES is a good place. Otherwise I do it like 1 of 500 said (originally taught this by Crockett on pwctoday may he RIP) I loop the return line and put my T in the bottom of the loop. That way there is always a few squirts worth of fuel there and there is zero risk of loosing an engine from the primer drawing in air. I tried a low spot in the return line at first on the Zebra ski and like Suke I was never able to get any fuel pumping when the ski had been sitting (when you need it most haha).

Yep matt hooked me up
You need a 8mm nut on that top starter bolt.
But I see pump blocks under that fuel rail now! Lets do a quick test. When your engine will spin over from battery power run a 1/4" hose from the impulse fitting on the case to a T that connects to both fuel rail fittings. Then T the line to the lower carb fittings. It can go to the tank or just a little jar of fuel. See if it draws the fuel in as the engine spins over.

Matt there are pump blocks under the fuel rail. I can do that test when I get to the point of putting power to the ski. Do you think I really need the extra fuel pump? I have not put the rear eBox and yet because I'm waiting on the exhaust tip
If those pumps have diaphragms in there they will pump. I never looked inside so I'm not sure. I'm happy to send a used pump if needed but I found the new one here for a pretty good price.... http://www.ebay.com/itm/Mikuni-Fuel...ash=item35f5ec083b:g:jz4AAOSweuxWTqLd&vxp=mtr and I could pitch in.
No don't buy it. It sounds like you already have a pump for each carb. Just T the two fittings and connect it to the pulse fitting on the case without kinks and with as little hose as possible.
Your two lower fittings will be connected with a T and connect to the fuel filter/water separator. Your two upper fittings will be connected to a T with that #65 main jet screwed in the single end. From there it goes to the RET barb on the fuel baffle.

These are the only clamps I use.
I use strong zip ties. Just make sure they are tight and they will be fine. I get in there with a pair of needle nose and get every last click before I snip the tails off.
