You can certainly install your own access port, if there is room to do so and clean out the tank yourself, but the post above is I believe the easiest answer.
I’m of the opinion that regularly adding a biocide will prevent most problems.
I would remove the stainer which will mean a longer dip tube, first strainers are not necessary if you have filtration which of course you do, its better for the junk to get into the filter and then you change it rather than clogging a strainer.
Plus a strainer like you have means there is a coupe of inches of unused tank that will eventually fill up with junk or water because you can’t suck fuel from the bottom, replace the tube with one that comes very close to the bottom and then if you get any junk it gets sucked out before it builds up into a mess.
Someone will soon tell you that you need a fuel polisher and if you had one this wouldn’t have happened.
Maybe, but especially if it pulled from a dip tube like the one you have, then it won’t pull anything from the bottom of the tank and junk would still build up.
I don’t believe your problem is asphaltanes But most likely biological, you need to add a biocide at the shock level and let it sit awhile before the fuel polisher comes, you want it dead, and he will suck out the dead bugs, then add biocide every time you add fuel. If you don’t kill them they will continue to grow and your problem will reoccur.
So far as controversy on using a biocide regularly, that’s from people who don’t know any better, in fact if you buy many better fuels they have a biocide in them anyway, Valvtec does, every bit that is sold
, but many if not most Diesel
doesn’t, it cost a bit more of course and every penny saved is a penny earned if your selling fuel.
When Valvtec fuel is available, in my opinion it’s worth a few pennies more, sort of similar to top tier auto gas.
Worth reading if you have a car
However I add Biobor JF to all my fuel, just as I did with turbine engine
On edit, buy plenty of spare fuel filters, particularly if you ever travel beyond where your towing Insurence can come get you.
You may not need them, but they are I believe a good thing to have plenty of spares.
