diesel won't run out of storage tank

[Boomerang]

got a 600 gallon tank mounted on concrete pillars 6ft high , inch and a quarter pipe 10 ft long to the feed trigger. have a 30 micron hydroscopic filter on the tank. have flow to filter , but only a trickle to trigger. usually works ok down to 150-200 gallon , but got 300 in and won't run . any ideas ?? ( it's gravity fed,) just changed filter so it's not that .

get a long solid pipe on the end of your airline & blow the hole clear? can you shine a torch into tank to see if all is well?
poss got the diesel bug making its mark? but could be something else

taken pipe apart , trigger ,pipe ok , getting fuel to filter just can't seem to get any flow . next option take filter off check flow without.

Pipe could have perished inside if its rubber and peeling away

Not wishing to state the obvious but have you checked the level in the tank? (that is, has someone nicked it all)

level ok 275 gallons in it .
perished pipe is possible will check it .

If your filter has a water absorbing core then you might have water in tank and its blocked the filter. Have you bought a filter that's designed for a pumped outlet? If so You wont get good flow out of it if on gravity.

Take the trigger off and try with out? Some may have a gauze filter in the fittings?

We had this problem once
Went to fill tractor up at harvest 5-6 years back, couldn`t get any fuel out of tank
Stripped nozzle down no difference, tried a few other things, still no good

Turned out the last load had had a lot of dye in it and stained the pipe enough for us to think there was fuel in sight glass

 

[Boomerang]

tried that runs very slowly , going to bypass filter tomorrow see if that shows up any problems

Filter full of water ,turned to jelly ,blocked outlet?

I had this with diesel stored in 45 gallon drums. Snow had got on the top of the drum, then alternate heat from the sun and freezing at night had drawn water into the drum. I could pour it out of the drum but it would not go through the gauze filter in the funnel to a smaller container. Warming it up cured most of the problem and I dumped the thickest layer of sludge. Your profile does not say where you are. Is water + frost a possibility?

I'd suggest syphoning out from the top, leaving the sludge at the bottom. Then knocking out the filter and decanting the last bottom layer into smaller containers, letting it settle, and syphoning off again. One of those pipes with a valve on the end off Ebay worked well with the syphoning for me and only cost a few £s.

30 micron gravity feed specific .

I’m betting you’ve got the bug and have a fine jelly/goo in the filter. If it’s a metal tank then the biodiesel may have cleaned the fine rusty corrosion off so it blocks the filter. Been there on both.

it's a metal tank, three weeks ago ran out fine , changed filter as it was 2 years old , new filter won't run . it's also got the exocet, but killer in it . but did read somewhere that dosnt work below 12 degrees.
