I don't know if they make it but i am looking for a relay.  The one I am looking for will operated by 12v on off switch allowing or not allowing 110v to a pump.  If you know they make them or well them please let me know.  I'll thank you in advance.

Thousands of them.

Need to know how many amps or watts the pump draws on start-up to give you a more exact reference.

Sounds like something similar to a project I installed years ago.   I have a 12 VDC switch on my dash. It is wired to a solid state relay at the rear of the bus that controls the engine block heater (110 VAC).   I used a Crydom TD1225 solid state relay.   The input side accepts 3 - 32 V Dc to close the circuit on the output side (maximum of 25 amps.)   Works like a champ.  I mounted the relay inside a standard sized electrical outlet box.

On cold mornings I used to have to go outside, walk to the back of the bus, open the tailgate and plug in a cord.  Now, from the warmth and comfort of the bus, I just flip the dash switch.

Thank you Sean!  I will get the info on the pump tomorrow.  It is a small half horse
power blue 1 inch clear water pump from harbor freight.  I intend to use a 12 volt switch on the dash to a relay to give 110 volt power to the pump.  The pump will be used maybe 4 minutes per hour of drive time as it will transfer oil from the 100 gallon oil tank to the 22 gallon heated tank at the rear of the bus.

Now this post was a piece of shear genius.  I do hope you don't mind me copying your engineering!
