good or bad?

and fuel filter

 

I have 183,XXX on original fuel pump, but changed fuel filter first time at 77,000mi, and then atleast once a year. My pump used to make a whining sound every once in a while but not lately.

96 f150 single cab
4.9 5 speed w/ k/n drop in and glasspack

 

how's the glasspack sound? and did you notice a change from the fuel filter?

 

Mileage doesn't matter on the pump. If it's within the specified pressure range, leave it alone.

Before you change the filter (and you SHOULD), look at the diagram in my EFI Fuel Pump album showing how to disconnect it.

 

haha you already showed me it about a week ago steve, but I got a friend that has same truck model as mine but its a 5.0.. buddy rebuilt his engine and all and he been teaching me a lot so far. He ganna show me how. thanks a ton though

 

Unless you feel lucky, I'd change it out ASAP. I had fuel pumps fail on about 5 E-150 vans. Every one of them was between 115-120K miles.

 

i do feel pretty lucky.. yet not THAT lucky.. ganna change it out in next couple days. ty for the advice.!!!

 

listen to steve...

 

The glassback sounds pretty good, a little growl(not v8 sound but deep tone), not loud in the cab. After the filter change, it may have been a little difference but some acted like I could tell a big difference, for the miles on the filter. Last time I changed filter I cut it open and it really didn't look to dirty but I have not seen any pics of how dirty the filter can get.

 

Why would u have to change asap? If its not broke dont fix it, even if it does go he has two tanks just flip the switch. My truck has 122xxx and both pumps working fine.

 

If you're not having problems, don't mess with it.

I've got almost 170,000 miles on mine and they still work fine.

 

Oops, didn't even think about the two tanks/pumps.

My experience was with multiple failures on a fleet of E-150's (only one tank/pump) 5 failures, with no warning, on vehicles all with roughly the same age and mileage- 10yrs/115K, finally I learned my lesson. Next time-change the fuel pump after about 100K. When you only have the one pump, a failure means a tow, a vehicle out of service and a drive to pick up somebody. I'd rather spend some money and change it at my convenience than wait til someone is stuck on the road somewhere.
