fuel filter question

[johnson89]

I have a 1989 90 johnson,been sitting for the past 6 years...put gas in it an it started up but the water pump was not working,so tore it down an got it replaced an working good now, but motor was not running very well an got worse the more I tried too run it.So I pulled both carb.s an they were a mess inside, 3 cans of carb cleaner later,an they looked good.I took apart the fuel fiter an clean it an replace all gas hoses from fuel filter forward.Got everything back together an it fired right up,I let it run idle about 10 min.s then shut it off.Well about an hour later tried to recrank it an it started acking like it did before I clean it.Well today I tore it back apart an the carb. are full of trash again(little black specks).This has to be coming from the oil line so going too rip out all the oil line.Is there anything I need too watch for about hooking of the VRO unit back up...I plan on putting pleany of oil in the gas untill I know for sure it is pumping oil again.Also can I put another fuel filter right after the fuel pump,that way both the gas an oil are filter.(pic 1) Pic 2 what is the little clear tube on the oil line...thanks for any help

Re: fuel filter question

If it is indeed a VRO unit, I would suggest upgrading it to an OMS type pump. More reliable than the VRO or VRO2 pumps. If you don't want to or can't upgrade then the overall opinion here is to pre-mix the fuel and disconnect the oil portion of the VRO pump.
There is no lack of oil warning with the VRO's so it could easily cause you some major headaches and bucks.
With the pump sitting for 6 years I would want it replaced anyway. My boat sat for 10 years and the ifrst 2 things I did was replace the impeller and replace the fuel/oil pump. Mine is the OMS style.
You may also want to flush out the fuel tank.

Re: fuel filter question

The little clear plastic tube is there so you can confirm there is oil (not air) getting to the oil side of the pump.

When you replace the oil lines, make sure you get as much air as possible out of the line (ie. line full of oil) before reattaching to pump.
