Quick fuel pick up question.

[Samjo]

1990 SP.

It's been sitting for a couple of years.

Long story short......I wasn't getting fuel to the carb, so I started back tracking towards the tank. Filter was clean. I pulled the pick up assembly off, to check and make sure the screens at the bottom of the tubes were ok, and low and behold...both tubes were gone!

Ethanol got 'em I reckon. Both only had about an inch of hose on the nipples, and the rest has crumbled down into the tank. I got some more hose, (And installed a clear inline fuel filter so I can see if it picks up any of the crumbled hose), but here's my question.

I'm guessing that the pick up tube going down into the tank, is longer on the reserve side, and shorter on the primary side, so it will run out on the primary side first. I don't have any old tubes to look at, and I didn't see in the manual any lengths stated. It shows one longer than the other, but not by how much.

So....how much shorter should the primary side be, than the reserve side?

Question number 2........am I asking for trouble if I don't get some new pick up screens on the bottom of the pick up tubes, or will the fact that I installed an extra filter be good enough. Logic tells me I'll be ok without them, unless it trys to suck up a piece of that old hose that is large enough to block the intake of the 5/16" hose.

about an inch or two. The bigger the difference... the longer your reserve tank will be.

I am (slowly) into a cleanup project and rather than being redundant, please check my thread in the 2-stroke pwc section "89 SP (5802) in Escondido"; my last entry has a bit about similar findings plus some extra goo. I would highly recommend pulling out the gas and oil tanks and cleaning them out, especially when you almost certainly know there is some junk in there (ie: screen filters). It is much easier to size the length of the in-tank fuel line when you are not standing on your head so to speak.

Also I have found over many years that I prefer to be doing things like cleaning out fuel systems while I have 2 feet on the ground rather than bobbing around on the water. Maybe I am just getting old and non-adventurous.

I will post some pictures on the above thread of my in-tank work with aviation wire-wrapping rather than hose clamps when I get out to the shop with my camera.

After fishing the screen filter out of the goo at the bottom of the fuel tank, I found that it was completely clogged. After sitting in a little acetone in a jar for a while and being swished around it cleaned up very nicely. The check valve works good and it sounds like all metal parts so I do not think the acetone hurt anything. The screen looks good now and air flow thru the filter is good so I will put the filter back on the end of the reserve pickup.
