Help with triple outlet pump installation
I'm installing a triple outlet pump on my 94 SLT 750 and want to make sure I get it right.
Attached is a photo of my carbs backplate, does this seem right and do I need restrictors with this setup?

I just did this to my 94 sl750 works great but yes the fuel restrictor is in the return line if they are the orig. fuel lines it should be in their. Get rid of the old fuel line if you still have them in the ski replace them all while you have everything apart. Lowes has fuel line for about 80cent a foot 1/4 inch made by watts. Everything looks good in the picture on mine I only ran one return line no tee's but thats me two less chances for a leak. I also mounted the pump in the same as orig. and had no problems. The fuel rest. is a little brass piece that is shoved in the end of the return line so when you pull the lines off look inside and put it back the same way one side has a big hole other a small hole small goes towards the tank. Good luck man.

I bought 15' of fuel line and plan on doing the entire ski including the pickups. Should all fuel lines going from the pump to the carb inlets be all the same length or does it not matter?

In the pic you have it backwards.. The return is on the top and fuel in is on the bottom.

Fuel return restrictor must be in place in the main return line to the tank (after all the carb outlets), as that is what creates the back pressure that maintains fuel pressure in the fuel system. Without the restrictor, the fuel would just flow right back to the tank through the return line, without enough pressure to properly feed the carbs.

Could this of been the problem with my ski not going past 4K RPM? The previous owner had plugged the carbs backwards?

When I bought mine the prev. owner piped the carb. backwards it ran but like you said only about 4k and then it would start to bog. I'm pretty sure beerdart help me with that prob. with the same picture thanks. Now it runs like a champ wait untill you feel the diff. when its done right its like a new ski
