Hi everybody,

As I plan to restart (didn't start for along time) a Dailmer x300 95, how to drain fuel tank because as far as I know X300 doesn't have any drain plug?

Thanks.

 

They do, well all mine have had.

Look at the sender unit aperture, follow straight down, and just under the lip of the tank should be a drain plug.

Thanks

 

The problem with the drain plug (when fitted) is that it is right above the diff and access is limited. The fuel will drain onto the suspension/diff and be very 'messy' to deal with.

I use the fuel pump if it will function after sitting inop. Jump the relay and disconnect a fuel line to direct the flow into a catch vessel.

In your solution we keep the residus inside the tank? How to deal with this issue because gazoline is probably very old?

 

I would remove the tank with the old fuel still in it.
Remove the fuel supply/return lines and drag it into the boot area.

Open the EVAP flange and pump or siphon the fuel into a vessel to discard.

From the ones I have pulled at the junkyard, XJ40's had a drain plug, X300's do not. One solution is disconnect the fuel line at the fuel rail, and jumper the fuel pump to run and pump the fuel into a container.

 

That keeps the last few liters and residu in the tank. The sender has a hole that is easily accesible from the trunk, you can pump out almost all of the fuel through there, and if you give a 10 year old a rag in his hands, he can clean out the bottom through that hole... That's what I did perhaps not the most politically correct way, I know...

 

Thanks ! The hole your are talking about is n°15 on the pic?

 

I believe I did mine through the hole at the back, where 8 + 9 go into. If I remember correctly, I first cleaned (well, my little cousin did actually) the tank while still in place, and I decided afterwards to pull the tank out anyway, so could have been through the hole on top, but I think it was through the level sender hole.

I certaily pumped out all the gas through the hole 8+9...

 

Is it easy ti pull out the tank? I guess it's better to empty the tank before because uit can be very hevy with 80 liters

 

If it is full, you better not open the rear fuel level sender hole!
Undo the fuel filter (above the rear axle, left side), hook up the pressure line to a garden hose towards a container and jump the fuel pump relay.

Pulling the fuel tank isn't the problem, it's reinstalling it that's hard. Mostly because the lines are really hard to access. You'll find write-ups here with detailed photographs on how to disconnect/connect those hoses at the bottom of the tank, directly above the rear diff.
I remember inventing curse words on the fly while I was doing that. Some parts are fuzzy, but that I do remember...

 

The only pita thing are the d- clips on the bottom. They are hard to see, because you’re working through the axle. They do not need to be removed only rotated 90 degrees, they function like a quick connect. Once they disengage pull the lines. Everything else is pretty straight forward. Best of luck.

The X300 tanks use a 'stuffer-pin' for the fuel outlet and return lines.
The older XJ40 tank pipes are different.(like you describe)

The X300/308/100 need a special tool to release the pipe locks.

bob

 

Hi Bob,

Do you where to find the tool for pipe lock?

Thanks

 

Any fuel line or airco tool will do. A member here used a 4 1/2" section of plastic pipe, you'll find the details on this forum somewhere..

 

OTC makes a twin-pack of the common 2 used in cars for fuel.
I keep all different kinds for different situations.

 

The X300 fuel tank can be siphoned as it does not have a anti - siphon trap in the fill neck

At least on mine

I think I used a 3/8 inch ( 9.5 mm ) OD siphon pump kit still in the garage to verify

 

Here you go: https://www.jaguarforums.com/forum/x...quired-163902/

Make sure tank is less than 1/4 full before removing the sender unit.
I siphoned through the filler port to about the 1/2 gallon (US) level, IIRC. My 96 VDP did have the flap that traps your siphon hose, whether that is an anti-siphon trap or not, I couldn't say, but it was relatively easily depressed by a long screwdriver to facilitate hose removal. Memory foggy, but second time around, I may've used a short length of PVC pipe to hold it open and slip the hose down through the pipe. The harder pvc surface didn't provide much purchase for the flap to dig into upon "pull out."

Nunger1330 made a different experience from me for the two times I've pulled the tank. Disconnecting the two lines above the diff is the only challenge. Reconnecting them is a walk in the park. Just jam 'em in until you hear the sharp click, then pull back firmly to ensure they are seated.

Don't forget to plug the internal wire harness (#22) back into #14 before buttoning up!

 

Hello All
Does any know how to access the fuel lines at the fuel tank for a X300 XJ6 1996

Thanks
