I've found that pumping fuel into the main tank that the air cannot escape quick enough and that the tank builds up a lot of pressure and can expand the tank... I've got a bit of a solution but I was wondering what others have done??

Scrol back to post 5 for picture on the modified series filler I fitted to our Puma 110.
I pump from the sill tank to the main tank with this set up and have no issues using only the main tank breather for both tanks, the high point breather ports on the sill tank are plumbed to the filler so as fuel moves across the air balances out.

I've done 2 now... First one was on my old '95 Defender 110 Wgn and the second one on my '09 Defender Puma 110.


My 1st attempt on my old Defender:


# It came with the Sender Hole already cut in - I made up a Ally plate to block this off and just used Self Drilling screws and Silicon - all good with no leaks


# The 2 larger holes on the top (1 at rear and 1 at the front) - I've used these as breathers with separate hoses that I've taken up into the engine bay up behind the brake booster. I've installed a Filter on the end of the hose. The other 2 holes on top at the rear of tank are already blanked off.


# Fuel Pickup - This is where I made my 1st mistake... I originally had the fuel pickup coming from the brass bung at the bottom of tank at the rear. This all worked fine for the past 2years until recently when I was driving some forestry tracks and had a branch/stick come up and hit the fuel pickup brass fitting, cracking the tank around where the female brass insert is molded into the tank & I lost all my fuel. I'm yet to fix it but have changed my fuel pickup from the bottom to use one of the blanked off holes at the top & rear of the tank. I've drilled out the blank section and inserted a brass fitting with a metal tube inserted (soldered) into the brass fitting as my fuel pick up. Once tank is repaired, I'll just use the bung at the bottom of the tank as a drain plug but this will depend on how the repair is done...


# Fuel is transferred into the Main tank via a good quality Facet Pump and this is tee'd into the Main Tank breather hose down near the main tank. I have another equalizing hose tee'd into the breather hose as well but at the top near the main filler. This equalizer hose then tapped into one of the breather hoses on the sill Tank. This prevents any issues if u happen to forget that your facet pump is on and just puts the overflow back into the Sill tank. This also helps out with equalizing pressure between the 2 tanks.


# In regards to filling the Sill Tank, the easiest option was a separate Filler installed into the triangle panel just in front of the rear Wheel. I didn't believe the fall from the Main tank Filler to the Sill Tank would be great enough and thus cause issues when filling up the Sill tank.


My 2nd attempt on my Puma Defender (note: my Puma came with a inner Guard 40ltr Aux Fuel Tank):


# When I ordered this Tank, I made sure that there was no hole for the Sender..

# I pretty much did the the same as my first install with the exception of Fuel pickup. I did the fuel pickup from the top to prevent what happened to me previously...


# Fuel Transfer is tapped into the hose between the Main and inner guard tanks. There is no breather/equalizing hose between the main and sill tanks. Providing I only transfer fuel across when my main tank is nearing empty a equalizing hose is not necessary providing the main tank small breather is clear(not blocked)... This may change as time goes on if I start having issues with pressure build up when pumping fuel across.


# Again, a separate filler was the only way to go for this setup, even though the inner guard tank has provision for a hose tee off but is next to impossible to make work due to position and lack of fall....


Hope this helps u in some way....

# I had to change the setup on my puma after the local LR shop removed the little breather hose that I thought came from the factory. Anyway... after this was removed I was having issues with pumping fuel across from sill to main tank as the air could not escape quick enough and therefore built up pressure in the tank and causing the tank to expand plus it took forever for the fuel to pump across. I recently installed a equalising breather hose between the 2 tanks and all is good and everything is now working fine.

# I cannot see how u can replace the factory filler for a "Y" joint filler and fill the sill tank from there without it taking forever to fill, especially the way some diesel fuel foams up... There just doesn't seem to be a good enough fall, especially if u are wanting to use a 50mm filler hose. I don't see going over the spring perch working really well either... but I could be wrong... If u use a smaller hose it may work but again, how long would it take to fill the sill tank with the way diesel foams up?

Finally plumbed mine up today…….

Hmm, I see pool noodles mentioned, whats it relate to?

I will need to loosen the brackets to put some protection around one of the rear breather elbows as it jammed up hard on the tool box.

Overall pretty happy.

Filling at the servo was a breeze….could hold the pump nozzle on flat out till it completely filled.

66L on the first fill…….

The fuel light on the main tank come on when I was driving to fill the sill tank. When I got home I transfer into the main tank which took 60L and around 25min to do it. Yep, I went back to the servo to fill the sill tank again to work about quantities

Had doubled our range……means we can now do the Simpson in 2 weeks time


Just have to wire in a switch and wack some bolts into the filler tomorrow oh…….and put some protection around the back breather.

I believe the pool noodles were just to protect the tank from any upwards movement. Not sure they are necessary but I installed them on mine...

I would be trying to make some sort of shield of some type to and silicon it in place to the tank to protect the fuel pickup if u have used the drain plug as your fuel pickup. I made this mistake and paid the price on my first 4wd outing...

Looks good Weeds. Enjoy the Simpson.
