Filtering your 2T oil #1
Quick one.
I have searched the forum for the posts regarding this little subject.
Who was it who put a filter in the line of their two stroke oil line?
What size and type of filter did they use?
I have been cleaning my 2T oil tank out after it was blasted/painted. Pain in the arse ,but got it to the point where there's virtually no crap coming out .
Err one and a half days of patience, pouring white spirit in,shake it up,empty it out into a clean white tub ,so i can see the particles.
Been filtering the spirits out with a diesel fuel filter so clean stuff goes back in. Clean the tub ,repeat ,on and on.
So,don't want to take the chance of running the oil in through the pump .
Not my choice to blast it but...
Thanks Dave.

Search for posts by GFrench and/or DEET... I think DEET has the filters and Greg installed one on the Black Widow after a problem?

Here you go Dave!

I raised the same question a while back and MarkT pointed me this way.

All the best.

You probably know this already Dave, but just in case you didn't, there is likely to be a metal gauze type filter inside your oil tank, just before the exit point. Difficult, if not impossible, to see from the outside, so flush your tank from that point as well.

Sorry if I'm teaching granny to suck eggs!!

Hi Alan.
Well if there was one there or is one there,it's U/S or the grit is so fine it's passing it. I would think the larger bits that came out would have been stopped though and clogged it. I cleaned it out first when it came back when there was no sight glass in and got loads of crap out. I could wipe it out with a rag there was that much in the recesses.I expect,it's grit that's stuck into the metal in certain places. Going to spend another few hours on it till it runs clean as the filters are going to be there as a back up.
Thank's anyway Alan.

Not a bad idea Frank and it has crossed my mind but i thought better of it due to the fresh paint on it.
So back to the white spirit,in,out,filter,rinse and repeat.

Filtering your 2T oil #9
I just wanted to mention that the concern I'd have is restricting the inlet to the pump so probably not a paper or porous bronze fuel filter but one with a simple strainer screen... or one specifically designed for two stroke oil filtering.

The visu-filter shown in the other thread is the screen type... sometimes hard to find so just wanted to mention that the "screen type" is preferred. You could always fill the tank with a measured amount of two stroke oil and time how long it takes to drain by gravity with and without your chosen filter installed if using something different.

Yamaha two stroke boat engines used filters in the two stroke oil tank lines... that might be another source for a filter?

I thought I covered EVERY safeguard in finishing my DT2 now this comes up. At first I second guessed myself, then realized I cleaned the oil tank very well, new lines, rebuilt pump, calibrated, and bleed. Started it up and everything seems to be working fine. Now, after rethinking my rethinking, I'm okay with it without a filter. I think a filter could become restricted over time and I'll forget to change it. You'd have to have a fairly rusted tank to have concerns with crap in the system. If everything is clean, no worries.
