Tank draining

[T33stat]

Any handy hints on how to drain the tank?

My project has been sat pretty much idle for the last 3 years before I bought her and it's a little stuttery at times, has half a tank of fuel that I can only assume is 3+ years old!

Unless I can find some other way I will just put a piece of hose down the filler neck and do it the old fashioned way!

Only way to really clean it out fully is remove it. Siphoning will get the fuel out but not all the crud.

I think the lowest entry point is the filler neck entry point. There is a flexi piece which connects the filler neck to the tank which should have 2 jubilee clips on it, you could tip the car back and remove the flexi piece and let it drain but there will still be some residue left.

There is a hole on the top of the tank which can be accessed by removing the rear seats (only the bottom half, which are held by just 2 screws), an inspection hatch (3 screws) and finally the lift pump assembly, but it's fidley and delicate plus you risk damaging the o-ring if it's old. Once removed, you've got about 2-3 inches in diameter so you'll be able to get a hose in there and look around for any rust or gunk.

But as duggers says, removing the tank is the only way to properly clean it out.

Some photos at the end of this thread may or may not be useful - that tank was from 1992 but had sat for around 10 years before I owned the car. viewtopic.php?f=12&t=19011

I don't think the tank is going to be full of gunk,m, the filler neck looks solid and the tank looks fairly new, just old fuel I think!

I will try the inspection hatch!

You can't get the rubber hose off between the filler neck and tank with out removing the filler neck, I would look in the top of the tank from the fuel sender hole and suck it out from there.
You can have problems sticking a pipe down the fuel filler neck to drain the tank as there is a flap on the inside of the tank which the pipe may get stuck on.
