I agree with all the above.

You may luck out but that diaphragm is going to get worse and you will end up stranded if you are lucky.

Or like cab said you could loose your van in a fire if you are not.

Can you amazon prime one to the house? Some stuff will get there same day or by 10am next day around here.

I keep an electric fuel pump in the garage for times when I need a quick fix and the pump isn't available local to me. Maybe look at an electric pump on amazon too.

Good luck
