Hi Mike,
Your fuel pump may be a solenoid type, not a small motor whine type.

Good evening all,

My mobile installation in my 2013 Jeep Patriot went well, and is operating FB. 

I do have a bit of noise, but something is a little odd about it. 

Driving along with my foot on the gas, there is a noise like ignition 
noise, it raises and lowers the number of bursts just like you would 
expect, but here’s the odd thing. Going downhill, and letting off the 
gas, the noise diminishes, and then goes away completely, leaving 
nothing but ambient band condx. Quietest mobile installation I’ve 
ever heard. As soon as I hit the gas again, it starts again. 

Now that’s kind of saying fuel pump to me, but every other vehicle 
I’ve had, fP noise is a high pitched whine. 

Anyone have any ideas?
