Can I take out my mid-tank and still drive the truck? The pump went out last year, and now that spring is here I need to replace it. Will I have to plug the fuel line or is it closed when I use the rear tank?With the price of gas I need all the tank space I can get! Thanks

 

Believe it or not it is easier to move the bed and work from the top, than to drop the tank. IMHO

The bed will have 6 bolts, take them out unplug the wires at the rear, and slide it back. All of the access ports are on top of the tank. You can handle the bed slide by yourself, but having a hand will work out nicely.

You will need one of those line seperator tools to get the fuel lines off. There is a ring lock holding the pump in, that you can remove by driving it counter clockiwise on it's tabs with a large flat screwdriver.

I would check the electrical connection to make sure the power to the pump is still good.

good luck

I would like to know if I can take out the tank and still run the truck.

 

My middle tank leaks.Well it did untill i ran it out.So i use the rear tank.I need to replace the middle tank or get under there and hope i can plug up the hole.My truck runs better on the rear tank then it dose on the middle tank.What i noticed is that my bed leaks,and must of rusted out the top of the tank over the years.

 

The truck will run, but if you take out the tank you will have to deal with the plumbing & electrical connections. You will need to protect them if you or someone else wants to use them in the future.

In addition the supply line is pressurized from the rear tank pump up to the check valve inside the in tank pump (fuel delivery module) Thereore the lines have to be plugged to hold pressure. I believe I saw on the forum someone mentioned plugs were available in parts stores but I don't know any details. Good luck.

 

You must plug both the supply and return lines going to the front tank. They are "Teed" together with the back lines along the frame. The only thing that prevents fuel transfer from rear to front is the shuttle valve (return) and check valve (supply) in the fuel delivery module in the front tank. If you remove the tank, you will be removing these valves. Do a good job with the plugs, especially on the supply side (40+ PSI).

 

I gotta replace my mid ship tank is gettin replaced tomorrow. Only problem is, I thought it was a 19 gal tank, but it must be a 16 gal. Crap, already replaced the sending unit with a 19 gal one, man this sux.Hehe, a well, thats what I get for ***uming.

 

I replaced the pump today. Bought one of e-bay for 70.00. It took about 5 hours. The biggest problem was getting the inner fill tube in place to attach the outer hose. Marc150, I think the mid tank is 19 gal. I know I have put 18 gal. in it . Good Luck

 

Well, it was a 16 gal tank. Dont know what the 19gal was for (ext cab maybe) but it was way to narrow and long to fit. $105 for the 16 gal. Only took 1 hr to install it, man this stuff is expensive. Hardest part was getting the fuel pump situated and the locking ring on. My fuel lines are stuck on there like a bear, so I had to fight with the lines to get it on there just right. Thank god good 'ol dad was there, he held the tank and helped manuver the pump.

 

Reg Cab, LONG BED = 19 Gallon tank. (or so my 87 said)
Reg Cab SHORT BED= 16 Gallon
Ext Cab SHORT BED = 16 Gallon (my 93 says this)
Ext Cab, LONG BED = 19 Gallon

Your mileage may vary

 

hey 92 Lightning,
I too had the same issue.I also did mine today Sunday .The side tank a breeze,
The rear was tougher.But I ahd to do it twice.I filled upand the o-ring was not seated,I didi it again and the same thing happened.Is it possible that the locking clip is not compressing enough?

 

There is a tab on the fuel pump that has to be in the slot. This keeps the pump in position.If it isn't in place the pump won't seal. I also used some black gasket seal under the pump before I put the o-ring locker . Good luck

 

THanks 92 !
I have figured it my fuel lines are compressesd slightly I had to pump out gas 11 gallons and it did not overflow after further looking and checklist questionning.It occurred that the fuel pump my be slightly turned the wrong way thereby kinking the line a little,hence pressure on the o-ringBTW,which way is the fuel pump supposed to be facingi.e. the little ports completely forward towards the pass. sideor driver.is there an illustration?
