Hi,

I need to empty gas tank and from the manual, there is a drain plug on the gas tank which does this. However, the manual continues to talk about pump gas out of the fuel pump.

So basically it says: 1) drain from drain plug, then 2) hand pump from the fuel pump.

My question is, how much can be drained from 1) or how much does 2) accomplish?

THANKS!

it's a saddle tank with two sumps... the left side gets continuously scavenged into the right, and the right side feeds the engine.

So where is the drain? If it's on the left, that would let you get about half the fuel out, then you'd get the rest from the fuel pump access on the right.

Thank you rasterman for your reply.

The structure of the fuel tank is shown in the picture. The manual says the drain is on the right side. (I did not check this).

So I guess the pump which is on the left side (drive side), it sucks fuel from the right side (passenger) which has the drain plug?

When draining, I guess the fuel cannot free flow back to right because of the bridge. So it is probably just a little more than 50% because of the left over under the bridge?

Should I just go with the return line method people talk about?
