1996 fuel pump noise

I have a 1996 F150 shortbed with a 302 engine and automatic transmission. It has a single tank. The truck has 132000 miles and I have owned it for two years. I have replaced the inline fuel filter.

Today I heard a buzzing noise coming from the truck while it idled in my driveway. Crawling under the truck I pinpointed the noise as coming from the fuel tank. It sounds like florescent lights when they are cold and hum.

So it seems as if the fuel pump is dying. Since I don't want to be stranded on the side of the road I plan on replacing the pump soon.

My question is, do you recommend any particular brand? Any to avoid?
Do you have any tips to make the job easier? I plan on removing the tank, not the bed.

Thanks,
Terry

Do you drive the truck often? Sometimes the pump will make a noise your hearing if it hasn't been run for an extended amount of time.

I only drive it once or twice each week. If I drive it more, is the noise likely to go away?

It may. If it's gonna be sitting with X amount of fuel, I would try to fill it with Non-Ethanol fuel and use MMO when possible. Shell has '93 without ethanol where I live, so I use it.

Ethanol fuel sitting in the tank for extended periods of time is not good on our older in tank pumps. And I won't use it in my lawn equipment.

Ok, here is an update to the fuel pump.

I bought a Denso (made in the U.S.A) from Amazon for $108 and a Motorcraft sending unit from Rockauto for $124.
I dropped the tank rather than removing the bed because I wanted to take the tank and clean it out. I will never remove the tank that way again.

I put it all back together today, put 5 gallons of gas in to get me to the store. Got to the store and filled up. Gas went everywhere. Got back home and discovered I had not gotten the fuel filler pipe back on the tank correctly. The smaller hose was in the tank fine, but the bigger vent hose was not all the way on and the clamp caused it to gap open.

Spent a few minutes removing the bed bolts, taillights and tailgate. Raised the bed and slid a 4x4 block of wood between the frame and the bed. I could then easily reach the filler hose and get in on the tank properly. I then put the bed back in place and reinstalled the trailer hitch that I had to remove to drop the tank originally.

It's all good now, I have a full tank of gas and no leaks, the truck runs great.

A lot of people on here will recommend using motorcraft parts where available as much of the aftermarket stuff is junk. I tend to agree with them. However if cost is an issue for you, you may wish to use another brand. Ive got standard motor product pumps in both my tanks, they have been in since december last year and so far no issue from the tanks.

I dropped the fuel tanks out of my truck as I needed to give them a clean and coating when I replaced the pump and senders. Personally I didn't find it to be to tough of a job, just make sure you run the fuel down as far as possible to make life easier when lifting them out. If you had a buddy to help you with it, make it even easier again.
