Two fuel ports

[dougb]

I just purchased a second 1990 B190 for the lower 48.....It has two places to put fuel but only one tanks......Can anyone tell me why there is two places to put fuel in this B190?

The pre-92 or '93 models had two fuel tanks - a 15 gallon in the front (well, midships) and 22 gallon tank in the rear. You should have both...if one is missing you're not going to have much range.

There should be a switch on the bottom of the dash, to the left of the steering wheel, to select between them.

Thanks for the help...............I do not have any manuals on the 1990 so your assistance is appreciated.
