Default RE: Fuel Problems 90hp Johnson 1996 V4

Here is what I have discovered thus far:

Compression check OK, equal all cylinders 115-120.

Water/fuel seperator filter was half full when I took it off, poured out fuel and found few pieces of jelly in fuel. Shouldn't the filter have been full of fuel when I took it off?

Checked primer bulb, still not firm but no leaks found, no jelly when I pumped it out.

Disconnected fuel and oil line from inlet inside cowling, found plastic inlet with jelly settled in bottom. I took fuel line off inlet and filter drained fuel and found no jelly chunks inside. I took the fuel filter out it was clean with just a few bits of trash in screen(cleaned and replaced).

Checked spark plugs, did not appear burnt or unusual. ( they have 16.4 hours on them)

Parts I'm replacing today: fuel water seperator filter, new gas line from filter to engine, spark plugs, primer bulb.

I am going to check/blow outfuel line from tank to filter after I replace the above items.

Other suggestions?
