Replacing the Fuel Pump

02BlaaaZer · 08-31-2009, 03:22 PM

Ok, I have the hard to start in the morning blues.
I have read all the post. I figured it has to be one of the known issues.
I am going to start with the FI cleaner, not expecting much.
Next I am going to see about replacing the fuel pump. I can't find anything about how hard this is. Is it in the gas tank, is it on the motor like it used to be.

Anyone have any input on this?

It is in the tank.

Change the FUEL FILTER before removing your gas tank to replace the pump!

Replacing the fuel pump is a MO-FO in these trucks!

Yes, fuel filter along with Sea Foam and replacing the pump in these trucks isn't that bad... especially if you have a lift in your garage

02BlaaaZer · 09-05-2009, 01:09 PM

Well, I don't have a lift, but I can do the filter pretty easy.

fuel pumps arent that hard with jackstands and a jack either, people are just exaggerating it

It also seems like a much easier job once you take it to a shop and they tell you how much it will be to change one out.

If fuel pump is needed to be replaced, then key word is fuel pump.

You will see everyone say to buy fuel pump assembly, problem is that it's over $300. Well problem is that they're replacing ENTIRE unit, when fuel pump ITSELF is only thing needed to be replaced.

There fore you replace the FUEL PUMP that go for $50-$150 depending on brands.

There's how to so you can look it up in stickies in Engine/Drivetrain tech section.

And I bet a lot of shops tell people they need the entire assembly but only replace the pump
