high speed death

[wdkingery]

Just delete that white box under the car by the rear passenger seat. I think there is 2 lines, one in an one out. Cut and splice and then throw that white box in the ditch.

That caused me to laugh out loud in class and gather attention to myself.

Thank you for the info.

Anything on a water separator? a 1986 6.9L IDI will also leak (air) at the water separator, and i haven't figured out a water separatin solution for that thing either

Get a filter with a water drain from a MK1 like R.O.R. sez.  Negates the other water separator; you can even use your old filter base just fine.  The racor is great as well, especially for getting fine particles out of waste fuel mixes.

Is water separation a big problem with those running WMO mixes?  I know that diesel has gotten good enough that a big separator really isn't needed anymore, but mixes are always the wild card.

Well I don't think I've had a problem with water, but it's inevitable that I will, because people almost always allow water to get in the oil before I get my hands on it. And I have processes for dealing with the water (mostly including leaving the water in the bottom of the  container and working from the top down) but I'd still like to have a backup.

So I had my lil pump (that I did not throw in the ditch) SLOWLY draining my tank, and I got under the vehicle to stare at the water separator while I was waiting..  I figured hell let me just open it to see what it does.. Well the whole separator was sucked up tight, and returned to the correct shape when the knob was turned! Damn thing was under hella vacuum! My poor injection pump! I guess I'm kinda glad I had the lift pump to take the brunt of it.

Reckon I damaged the ip? Would be a shame that a restriction wiped my pump out before my wmo cocktail managed to.

I guess it's still possible that the clog was in the tank, and the water separator was just the thing to show the symptoms of vacuum. But I cut the damned thing loose, and I'm fixin to splice the lines back together and find out. Or maybe ill drop the tank.. Can't really do much from inside the car through that little peep hole.

i would delete the mk2 water separator AND filter..

i would UPGRADE to a mk1 filter/separator, and a racor if you can afford it.. they are about $100 for a base and element..

ive got no dedicated water separator on my car, just the built in separators in the mk1, and racor filters.. my Racor has a clear bowl on the bottom.. makes it easy to check for water..

you say the water separator also has a filter on it, or you refer to the filter up near the IP?

no, im saying i would get rid of the water separator (under car)

and i would also get rid of the STOCK MK2 FUEL FILTER AS WELL

and replace it with a mk1 fuel filter.. they have the water separator, and filter all in the same package..

and you can do everything you need to, thru the access cover in the car..

golf is easy.. Jetta you have to climb in the trunk...

It seems the fuel lines prevented me from lifting the sending unit out of the tank at all. I was hoping to scoot the sock off the bottom of the pickup tube (assuming it has one)

[fatmobile]

There's a check valve in the line in front of the seperator that should be removed too.
I think it's all 5/16"/8mm stuff.
 Your fuel filter in the engine bay probably has a water seperator on it.

I use 95 % acetone (not one of wive) in a range of 0.2-.5%,It BOND water and oil so no way your IP will ever see JUST water,and you get some clean.

Nah, picking up litter makes the local civics groups feel important!

i so wanted to say that, but i didn't actually litter..

got any advice on a water separator? i'd like to have one.

i didn't see how your info shows how to delete the separator, but i'm sure i'll see it when i get home

x10 on this. 
I went with a big Racor turbine filter off a boat. 

I also deleted that pesky separator, mine was badly leaking.

[wdkingery]

ugh.. well i figured it out, finally.

it would have been HELPFUL if the fuel pickup could have been removed inside the vehicle, without dropping the tank.

the clean spot i made after it had been removed.
what is the point of this thing when i have a fuel filter just feet away?!!? i could understand in a gasser application where your pump is before the main fuel filter but .. geez.

and my tank had the shinies in it. not a bunch, but it was certainly sparkly in there.

idk what kept you from removing the sending/pickup unit, but it is 100% possible without dropping the tank.. you cut the stupid band clamps, slide the lines off, and remove the sending/pickup unit..

[wdkingery]

yeah i thought about that, but then i had the delusion that i would be dumping the tank and cleaning it out ..

what do you mean by the shinies?  When you say not a bunch, and sparkly, I take that to mean metal flakes in the waste oil, is that what you are saying?  Or are you saying it is clean.

What is the makeup of the blockage on the screen, is it hard grit?  Looks like VO polymerization, but coated with oil to me.  Is it soft?  

[wdkingery]

i'm glad you asked, as i'm worried about it.

it was metal flakes, and it's NOT from my waste oil. i filter down to a micron.

i had decided it's either from the pump i bought a year ago, or the pump before that.

I don't use any VO, only WMO.

It was like.. mud essentially. brown, plantlike material. was soft not hard.

it is the sparklies i am worried about, although that tank gave the appearance it had never been down in 27+ years, so i guess it would be safe to say it had 27+ years to accumulate the shinies.
