drain point on the fuel tank

[powerboatr]

anybody install a drain valve on the fuel tank to remove water and sediment?
I pulled a fuel sample sunday and was SHOCKED at what i got
sand and gobbly gook and some water.
this is a place i fill up at every othere week.
we did just finish a road trip but i made to jville on one tank and then filled up with 10 gallons from my jerry cans I filled up before i left. then topped off at the chevron for 3.19

Nope, but I dont see how it would be that difficult to do...I have no doubt what is layin on the bottom of some tanks...I run mine down to almost nothin!! But Im sure that there is still some water sediment ect...in it!!

I have all the neccasry aeroquip fittings but am hesitant to drop the tank
i wish i had a self sealing compound for the plastic.
IF i drop her i will go with a #6 fitting with an oring seal.
just nervous about going inside and what i may find

A #6 should work ok..just make sure that the O ring will seal it up good, are you going to use a poppet type, or a screw type? Let us know how you make out!! If you find anything funky, clean it as best you can, and then let her ride!! Good luck!!

I am more than likely use a pop type valve so i can drain just a small amount.
looks like aricraft spruce will be getting a call

Those are good valves to use...we use them on our C-130 fuel tanks to drain the condensation out of them also!!

I think i found one at aircraft spruce. now I need to find the time to pull the tank.
push up and turn to drain. should work well
I am leaning towards a bulkhead fitting inside with a o ring. then tap it to accept the drain valve.

That should be the ticket there bud!! The bulkhead fittings will ensure a leak-free seal. The only bad part about them is they will seep after time when the O ring deteriorates....but that wont be for at least 3 or so years!! But if you can, please post a few pix of the process, if you can!!
