885 Fuel Line

Post by dwighted » Fri Jun 28, 2019 5:29 pm

Guys,

I've been working on our 885.

Got the tank cleaned out at a very good radiator shop here in Iowa.

Now working my way down to fuel pump and filters.

The reason for all this is that I've let fuel set in the tank too long and have black goo in the lines.

From what I can read it is due to algae.

I've got the line down to the fuel pump off, the pump off and both filters off.

I have new pump, new filters, but where am I going to find a new line from the tank to the pump. The line is a hard plastic, might not be original.

The line just slide off of the tank outlet tube, but the connection to the pump looks like the line was pressed into the threaded nut.

I don't see a way to get the line and nut separated and I don't want to mess up something if I can't get a replacement for or fix it myself.

Also, what will dessolve that black goo?

Normally a good blow through with high pressure air is sufficient. A cellulose paint thinners type solvent may be beneficial or brake component cleaner.

DB2D,

Thank you for the info.

I've got the nut to the fuel pump all cleaned up. I used some brake cleaner and a wire brush.

I've got some new fuel line that came from a hydraulic hose place.

I've got to find a 5/16 compression sleeve and I'll have that little part back in good shape.

Next is the fuel line from the pump up to the filter input. That line seems to be steel so should be easy enough to get clean.

The compression sleeves are called ‘olives’and are readily available.

DB2D,

Got new "olives" today at the home store in the plumbing section.

The sediment bowl is all cleaned up. It is the short bowl and the pumps we get here in the states has the long bowl, but no big deal, R & R.

Again thanks for all the help.

The sediment you have got is virtually certainly not algae but rust coming from either your storage tank or the tractor tank.
Make sure your storage tank has a slope from front to back. There should be tap there, or plug to drain off water and sediment.
You will always get water in your storage tank from condensation and this causes rusting in steel tanks
you may also get gunge coming from waxing of summer fuel which has got too cold in winter time.
Waxes are added to fuel since they are lubricious and cheaper but need to be kept above 5 degree C or they will cloud and block filters.
Fuel tanks are always best kept inside a warm building to prevent condensation and waxing. Once fuel has got cloudy it may need heating to to clear it.
it was common in the UK to add up to 10% kerosene to fuel in winter time to prevent this waxing from occurring, once waxed though it will do little to help .
Some people say you should not add kerosene to fuel which goes in common rail engines , but theat is not an issue here and we always ran our tractors in winter time with it added

Steve,

Thank you very much.

Since I started working on the fuel system, I've done some reading online. I'm sure it is wax now, I've tried several different solvents and nothing will cut the brown goo. The inside of the tank was indeed rusty and cleaned by a very good radiator guy. I don't have a storage tank, just a 5 gallon plastic jug. I'm sure what little fuel was in the tank separated last winter, we had one morning with -28 F and the next morning was -33 F and the tractor stays out in a building, but no heat. I've found my 200 watt magnetic heater that I will put on the tank to keep the fuel warm. Also I'll get the tank full and put in some winter treatment. I live close to a truck stop so I will ask them when they get their winter mix in their tanks. I know I don't want to clean the brown goo up again, what a sticky mess.

that is cold!
I have no experience of those sort of temperatures, Kerosene will help but I really cannot say if it will take it that low. If you can drain the tank as low as possible before using winter grade. Also do not get it from your truck stop too soon, as there is a fair chance they fill up their tanks before they are empty, so you will have dilute winter fuel till they have filled a second time.

Fuel stations in Finland can have for sale 4 different diesel fuel to suit different ambient temperatures. Summer fuel for temperatures down to -5 centigrade, interim fuel for temperatures down to -15 centigrade, winter fuel for temperatures down to -30 centigrade and arctic fuel for temperature down to -44 centigrade.

I believe our summer fuel is rated for +5 and winter only down to -10
it is apparently quite a bit more expensive to formulate those fuels for very cold work

Steve

I checked over at the truck stop and the guys at the counter didn't seem to know much about ordering of the fuel.

I'll get some winter treatment from our farm store.

Ollek,

I really hope we don't get to -44 C, -47 F is just a bit much for me.


I was talking to the starter guy about how my starter was coming, and the subject of the black goo came up, he told me to try oven cleaner on the black goo.

It worked, took about five cycle of spray, let it set for about 5 min, then rinse with cold water.

Now when I get the fuel sender unit I will be able to get fuel system all back together.

A point to bear in mind is that fuel can wax up in the fuel filter, so even with a magnetic tank heater it's possible that the filter can get blocked when it's sat in freezing temperatures. Worth making sure that you've a spare available.

I sook up at )'C never mind the negative temps that ollek speaks of. I would be a big bear and hibernate.

I do like working in the woods when it is around 10 to 20 F, when it gets down much below 0 F (which is -18C) I can usually find something to do inside.
When I brought my injectors in for service the shop owner recommended Stanadyne diesel additive especially for older engines, he said some of the other products on the market are worse than nothing. Since then I add some with each fill up. I suspect everyone has their favorite additive and they do seem to prevent gelling of the fuel. I had some gel up years ago and there was no way to get it running until the weather warmed up some. I have always bought diesel in 5 gal cans, partly so I am always buying it in the season it will be used. I found it is a good idea to use a big funnel that has a fine mesh gauze in the bottom, this seems to trap water and ice but even more important the the dust and crap that seems to settle on the top of the can.

Most diesel additives are snake oil. However one that will stop the gelling is certainly worth considering if you are prone to extreme temperatures or you are not sure you have winter fuel in.
Keeping the tractor and the fuel store inside a warm shed avoids most issues
