cleaning out gas tank?

[bassackwards]

I'm installing a new 255 lph fuel pump and have the tank off. I see a little trash down there and wonder if I can just spray it out at the car wash then let it dry in the sun for a couple of days?

We have 3 sunny days in a row coming up

Car wash guy will probably hunt you down and beat you

But yeah, a good flush will work if you can get the rest of the water out after
