hi all, new to the boat scene,just got mine last week,87 ps 190 with 690 hrs on it, anyway, the previous owner was having issues with getting trash in the carb so they pulled the pickup hose out and shortened it.
problem is they cut too much off of it. if it gets below 1/2 tank it will run out of gas in the carb for a few seconds,spit and sputter and when the boat sits level a second or so it will pick up and take right off again.

going out to remove the tank as soon as i get this posted and see what i am working with. if its full of crud then out it comes and a complete cleaning with follow suit. but i do not know how long to make the pickup hose once i get all this fixed.

hope you guys can help!!!!


Thanks,
Mark

ok, pulled the pickup hose out and it has not been cut,it still has the crimped on end,a weight with a hole in it i guess. now upon inspecting it there was no crud in the tank that i could see and no crud/buildup on the end of the pick up hose,i then went to the front and started at the carb inlet and took the feed line loose and no gas came out,strange i thought, so i loosened it at the pump and the feed line was empty to the carb,not even a drip. i just took it out the water 2 hours before i started all this......i would think it should have at least a drip or 4,anyway, took the filter off the carb and its clean, took the feed hose from the tank off the pump and free flow was great,surprised me actually, and no gas came out the pump, so i took the pump off the engine and tilted it and got about 1.5-2 oz. of gas out of it. i didnt think this was right so i got a pump and put it on,im gonna let sit about 2 hours and see how much is in the line to the carb. i hope it will be full.:cool:

now, i am into f. injection on the automotive side with aftermarket systems like FAST, big stuff, megasquirt, to name a few, it has been a few years for me with a carb, but im not totally in left field on this by no means,just the marine specifics are getting to me,lol....anyway i hope someone with more marine experience than i can chime in and shed some light on this issue.....:D

Coast guard doesn't permit fuel to stay pressurized in the fuel lines.

Ok,so all gas will drain back through the pump,into the feed line from the tank.....ok,told you i didnt know anything about marine stuff...lol.

When i got it from the guy he said if it gets below 1/2 tank it will stumble when you turn hard,because the pickup was shortened by the previous guy he got it from,but it looks uncut. Should there be a check valve on the pickup tube? I could blow through both ways....

Affirm...there is a check valve atop the tank with a spring loaded BB inside. Earlier this year I took mine off and cleaned it up -- it was full of gunk.

By the way boats must use A1 type fuel hose which is marine rated...

I had mine out this summer - didn't measure length, but I do have a tip for you.

Hold it up next to the tank approximating how long it is, compared to the plastic of the tank.

That should let you know how much to add.

Mine has a spring inside, the spring was full of crud - which is what caused the running issue, otherwise the crap gets caught by the racor 110, the fuel pump filter, or the carb screen. And personally I've never seen it get past the racor 110.

Go back to your pick up, there is a crimp at the top where the rubber goes into the pick up, this isn't regular fuel line, it is more like tygon or silicone, or urethane, not sure which, that spring is important.

Also to me, if you want to improve upon this factory design, you could probably extend the tube towards the bottom by shoving some tube into the weight with holes drilled in it

Yea, i held it up to the tank and it was long enough to go to the bottom and then lay out about 3-4 inches at the bottom of the tank,but i didnt see this check valve.... I remove it again and double check it...

and heres my problem......

and after...

but upon re-assembly i rung off the check vlave in the pickup....:( but i got it out and shortened the spring and put it back in the nipple, not much thread left to work with, re-tapped the pickup to get ot the end that rung off because it would not budge with an easy out, lightly ground the nipple thread to take off some diameter so it would thread in,being pipe thread it was larger next to the hex than at the tip. put some thread sealant on it and screwed it back together.

struck out to the lake and it run like a champ, half a tank and done about 5 30mph hard turns and no sputter at all.

but i had to reset the rear float level in the carb as it was dripping gas out the rear ventures(sp?) while it was running. i think it was doing that when i got it because it cranks much better now than it ever has.

man i am glad i got on the site!!! the knowledge is everywhere :cool:

Glad that helped it.

Here's another view of what I ran into.

http://i45.tinypic.com/iefjao.jpg

The tygon tube has a coil spring in mine to make it stiffer. Mine was ALL kinds of packed with the same sort of stuff yours was, so I separated mine at the crimp by pulling the rubber tube out, and then pulled and cleaned out the spring.

One question on the newer one,is that a return line that is plugged off beside the pickup? If so that would be great for my F.I. conversion later in the winter.....

By the way, how much gas do you guys leave in the carbed boats over the winter?

You may want to reconsider the newer configuration. Jsut cut a small opening to fit in the top of the fuel cell and install. Worked very well on my 93.

.

Heard a lot about the OEM fo these tanks in this thread.......however did not see anyone say who the OEM is!

Need to address my old tank, fuel pickup, and fuel sender issues as well, looks like a nice set-up in picture

Ok I'm hoping 88 PS190 or someone who has removed the fuel pickup can help here. I found the anti-siphon valve full of aluminum shavings, plastic, rubber and whatever else. The problem is getting the pickup out of the tank. In the process the pickup hose also came off, the crimp was pretty loose and the Tygon hose did not have a spring in it as posted earlier in this thread on the 88. It looks like there is a bushing molded in the tank that the pickup screws into, however it just spins now after trying to unscrew it. I tried to use the locknut and get it and the bushing tight together thinking the pickup would break free but it won't. It gets real tight but still won't break loose. I have a new pickup and anti-siphon valve but I'm a little stuck getting this out. Any ideas? What about just threading the new one into the tank?
4 pics below, one from a scope inside the tank, ignore the date on it, it wasn't set.

Is the board stumped? Never thought that could happen. :confused:

Bit stumped. Bushing into the tank spinning is a real issue - if stripped that needs a tank replacement unless you have a way to seal it up.

Back the elbow out of the bushing and withdraw from the tank and it really doesn't matter what sort of tube you have, american skier used to just supply a stiff plastic pick up tube with an angled cut on the end. MC usually has a weighted end but again just a pick up from the bottom of the tank.

The antisiphon valve, if full of weird crud clean it out or replace it - either way.

After that what is the running issue you are chasing?

Thanks 88, it has me stumped and the thought of damaging the tank is what stopped my progress today but I was torquing on it hard when holding the nut with a wrench against the fuel fill inlet and feeling like both the nut and the bushing were squeezing themselves together and pinching the tank hard but the 90 wouldn't free up.
I have the new auto-siphon valve and a new fuel pickup that has a straight rigid pickup tube that will always sit on the bottom of the tank. The valve was nearly identical and found at a local boat shop.
Thinking about calling Inca tomorrow to see if I can get any input from someone that might have been around 30 years ago! Otherwise I'm going to research just threading the new pickup into the tank and plugging the existing 90 degree fitting. Whatever pipe dope MC used has setup like concrete over the years.

Edit:
I was chasing a stumble at/near WOT. Rebuilt the 4160 last summer and the stumble was part of that issue although the Carb certainly needed it since it had never been done. Anyway this year I had an poor idle issue and tore the Carb down again and found the primary float out of adjustment and the needles from last year weren't sealing properly so got that fixed with a new kit and then the high end stumble showed up again. Previously blew out the fuel line from the water/fuel separator back but that anti-siphon valve was so jammed up its amazing it even ran.

Got the aluminum fitting off the tank today. Used some Freeze-off and some firm but gentle torque and eventually it gave up and broke free. Thought for sure the aluminum 90 fitting would break off like the anti-siphon valve did but it hung in there for the full ride. Popped in the new pickup tube and anti-siphon valve and tank is back in the boat and ready for the lake test. I hope nobody has to go through this it was a pain in the @ss!!:mad:
