I eliminated the sock filter on the inside tank pickup tube. Installed an inline metal 3/8 filter (like a GF-2 but in 3/8) in the suck line, and the stock Ford inline filter on the pressure side using the factory frame bracket also. I use the snap on type factory fuel line fittings everywhere, so the installation is fully factory compatable. The pump is mounted high up behind the differential on the trunk floor doubler brace and is no problem because the original tank's delivery system comes out the top of the tank anyway. It primes perfectly every time.
Never had one minute's trouble in 58,000 miles on one car, or on any car. yet.
I use the original fuel tanks and the only problem I have is that on a maximum effort launch with less than 1/2 tank of fuel the original tank pickup uncovers and I get fuel starvation about 40 feet out of the hole. So when I race, I make sure the tank is full.
Just my experience. Did the first 5.0 SFI conversion back in 92.

|fitzwell||Napa used to make a mounting kit.....rubber biscuit with a stud out of each end....works fine. Pump needs to be mounted as low and close to the tank as possible. Make sure you use a good, high capacity filter before the pump.A normal 3/8 inline filter will not get the job done......................don't ask|

Factory frame pumps are installed inside of a thick foam tube and then inserted into a bracket so there is no metal to metal contact. You can design a bracket by wrapping the thick foam in metal and attaching that tube to the frame bracket using worm hose clamps. Also isolating the pump with rubber lines between the hard lines is necessary. You might also need to insulate the floor/frame panel with some anti-vibration acoustical material to stop harmonic vibrations through the floor pan.
Any electric pump should be AT the tank.
For my 5.0 SFI cars I scarfed my pump bracket from a frame mount Merkur Xr4ti. It is silent. With the pump on, engine not running, you have to get by the rear of the car to tell if the pump is humming. I used the Auto Zone E-2000 pump made by Walbro. It is good for 325 hp. I mount them on a doubler bracket on the trunk hump behind the differential.
Frame mounts are also used on Ford light trucks and vans with dual tanks. Some Fords have an in-tank delivery pump and the pressure pump is mounted on the frame rail. Especially trucks with dual tanks.

cool rockin daddy has got it right,some electric pumps are quieter then others but they all make noise.so you have to deside if you can live with it or not.
depending on the shape of the pump i would try insulated band clamps.

|cool rockin daddy||Welcome to the world of electric fuel pumps! Noisy as h@#&! Try to put a rubber insulation pad of some kind between pump and frame. I keep on preaching this ad-nauseum but if it is not a strip car, put a mechanical fuel pump on it. Good luck.|

Fuel Pump Making Loud Noise
I just finished the conversion of my 51 Willys Jeepster. I installed a Mustang 5.0 HO drive-train with the 5.0 suspension. Everything went much better than planned. However, my new fuel pump is making a loud noise. I installed a Carter P5000 fuel pump and mounted it under the Passenger seat to the frame. I thought maybe I had a defective pump so I bought a new one and it is just as loud. What could be the problem? If the pump is naturally that loud could I use insulation to help quite the pump? If so what kind of insulation should I use? Thanks in advance for your help.
