Well #1 Fuel pump went out in the truck wile driving on 183 N this afternoon it lasted 14 years good run, I love these old Ford's with the two fuel tanks each tank with its own pump, I switched tanks and off i went !

 

The front one is such a joy to get to. LOL

 

Sence the Front tank is almost full we are going to use the Lift to lift the bed of the frame to get to the tank. Thank god i had fuel in the rear tank to keep driving, However my 96 Has the "Cross Flow problem" i will only be able to drive it for one or two days untill some of the rear tank fuel transfers over to the front tank and fills it up compleately.

 

A lift.. I am soo jealous. LOL Sounds like you got the bases covered.

 

Its not my lift, i have some mechanics i have known for ever like family, thay do alot on this truck for repairs, Its good to know mechanics that you can trust

 

I actually prefer to do the front tank over the rear tank.
I realize that pulling the bed sounds easier, but it rarely is.
Since you have access to a hoist, I would do it from underneath.
I would prefer to siphon out the gas, then undo the fuel lines and wires, then undo the straps and let the tank hang by the filler hose.
This will give you 8 to 10 inches of height to pull the pump/sending unit out.
If you will take the time to remove the drive line the whole process will go much easier.
Oh, that's right, I just did this last week! I just wish that I had known the tank was full before I undid the straps(sunken float).

 

I droped it off today the tank is full now thanks to the cross flow problem, thay are going to go ahead and drop the tank insted of lifting the bed BTW his price for a new Mortorcraft fuel pump is $242.00, the Ford House wanted over $300 for a new pump.

 

That sucks about your pump. I still don't understand how a 96 can have the crossflow problem. Someone correct me if I am wrong, but I thought that issue was resolved on the 94 up trucks.

 

He has a bad check valve or shuttle valve in the front tanks FDM and needs to replace the front FDM (Fuel Pump) on the 96.
The filling tank is always the bad one from 1990 to 1996+.

Yes they fixed the bad FPR in 1994 that made all the check valves go bad in 1993.
But that does not mean things still can not go wrong with the FDM.

 

I just wouldn't have expected his truck to have that issue. He said it started doing that a few years after he got it. It just seemed weird to me.

Your right though. Things can still break or get fouled up and need to be replaced.

So, If he gets a new front pump will that probably fix his issue?

 

Well yes but it is the FDM, the pump is inside the FDM.

Your rear fuel pump on your 96 has a bad screen or the pump itself is on the way out.

 

It is bad on the front tank and not the rear fuel pump (tank). A bad rear pump or screen will never cause this.

 

The front pump is replaced, i just filled up the rear yesterday so will see if it still tranfers full.

 

Really?, The transfer between the tanks is because the rear pump flow is weak and cannot close the transfer valve, ultimately a weak pump or plugged pickup screen WILL cause this from reduced flow volume thus causing the valve not to close and making fuel go in to the front tank.
