Ok so I've still got fuel problems. '94 zx600 carb and I'm flooding out. When I moved the gas tank down, I had to add a fuel pump. Have rebuilt the carbs and set the floats. If I let the pump run continually it floods the carbs. Here's the fuel pump http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Electric-Fuel-Pumps-Univ-Mr--Gasket_5400317-P_N3339K_P%7CGRP2030P____#fragment-3 It doesn't say psi but I'm thinking the packing said 5psi. So was going to pump to a smaller higher tank and gravity feed carbs overflow back to big tank. But I thought of an easier way if you guys think it would work. On the output side (pressure)of fuel pump install a T on line, one to carb and the other back to a T intalled in tank where the outlet is. There is only 1 thread bung on tank and that was the problem with using 2nd tank, having tank welded with 2nd bung. I think this might work and for the $5 worth of parts will try it before doing the 2nd tank thing.

Hey Carl, a few other guys I've seen do the second tank and it works, but I say try your other idea sonds OK ya got nothing to loose, well maybe keep a fire extinguisher handy :o and see how it goes!! As you say it's gotta be better then doing the second tank... ;D
-
Buy a ten dollar fuel pump regulator. The little round silver ones that you can set the pressure down to one psi.
-
Fast, thats twice what the other way would cost. Cant piss away money on this buggy hobby ya know. LMAO LMAO Might try that too.
-
We all know Fast likes to spend money ;D ;D ;D
-
Free to a good home. You pay the post man.
-
the carbs for my last engine (gsxf 600 suzuki katana) couldnt handle more than 2.8 psi is what the manual said.. anything above that would push the needles open....
but someone made a retro fit spring assist for the needle and float assembly, for switching to a fuel pump setup, vs the gravitry feed..
-
Yup you need to be @1.5 psi. or less...you could switch over to sled neddles and seats...since they are already calibrated to handle feul pump pressures ;D

Dang Fast, you must got a warehouse full of stuff. Man sure can collect a bunch of extra stuff from trial and error buggy buildin. I'll be in touch if I "think" I need it. You da man.
Fast, ever hear back from rack snuggy man? rofl rofl rofl

Ya you tend to collect a ton of sh$% when you have been doing buggy's as lone as I have. LMAO LMAO You have no idea the crap I have in two shops five VW vans and a big barn. I can't find sh$% I want some times. Know I have it but where. rofl rofl rofl drowning
Mite start a bidding site like fleebay here just for my crap. 8) 8)

Well against my "man" judgement, I decided to do this right the 1st time. Head hurts from beating against the wall doing sh!t the long hard way. Picked up fuel reg made by same fokes at pump, one end will thread into pump or can use barb fittings anywhere inline. Adjust from 1 to 5 psi in 1/2 increments. Its chrome too, so bling!!!
-
Damn it Carl I wanted to see the pics of ya do'n the other one to see how you were gonna do it. ;D
-
i'll see if I can whip up a little drawing for you then. ;D I do believe the other way will work.
-
Cool can ya doit in crayon so I'll understand.. rofl Seriously though I wouldn't mind having a look at what ya had in mind! If ya don't mind. ;D
-
Just for Reidy: ;D ;D ;D
-
And for everyone else. No leaks. ;D You can see where the gas washed the K N filter oil onto the prefilters.
-
was this motor gravity fed factory? if not get a stock fuel pump or off of another model and let the ecu control it like the 900 ninja. one of my old rails. the damn pump had points in it and had to be cleaned every 2 years.
