It looks like Jon has a Gerotor style pump which is much quieter than others. I have found the Holley pumps to be LOUD!!!

If you start with a cheap, loud pump, you will put a lot of time and effort into quieting it down. I spent a lot of time working with isolators, enclosures, etc to try to quiet down an electric pump. No matter what you do, it will be quieter, but will still be loud.

Your options (IMO) for a "quiet" electric pump are to either drop your tank and do an in-tank pump (best) or spend the money and get the gerotor style pump from the get-go.

The plus of the in-tank setup is that you have the option of swapping to a new fuel injection setup in the future if you choose to.

Anyway though, if you only want to spend $20, expect $20 performance.

Yes, generally one would want to mount the electric pump (universal/remote/inline) to the rear of the vehicle as these units are more efficient at pushing fuel vs. siphoning; as close to the tank as possible to reduce the length of the inlet/suction line; and as low in relation to the fuel level as reasonably possible to reduce the lift requirement on the pump. Also, I like to have the inlet/suction line one size larger than the outlet/pressure line to aid efficiency.

And, void mounting the pump to flat sheet or thin metal surfaces, or surfaces shared with the occupant compartment, as this amplifies the addible noise from the pump unit in operation.

As far as pumps, in the application relevant here, maybe consider the Carter product such as #P4070 or #P4594? These are not the noisiest units ever experienced, and have proven in the past to be durable (nope, I won't get a check ).

Scott.
