Hi guys,
After my car conversion I was having some filler problems, ie I was having difficulties getting fuel in the tanks. I just had some rectification work done where we swapped the filler hoses around (meaning the main tank becomes the sub and vica versa) but we did not swap the breather hoses. When I was driving
home I tried a sub tank transfer without any luck. The pump is working and the dash light is on just no fuel is being transferred. I used the sub tank 3 times last week with no problems.
Anyone have a clue, my gut tells me that it's the breather hoses.
Thanks in advance.
Kind regards

You need to give us more
information....
What model/engine previous and after conversion?
Is it aftermarket sub tank?
Which Light are you talking about being on? The one in the instrument cluster or on the sub tank switch?
On the GU Diesel patrols (it looks like that is what you have in your picture) the sub tank pumps fuel into the main filler hose near the filler, so if you have swapped the filler hoses you will just be pumping fuel out of and back into the sub tank and it won't transfer at all. Open the fuel caps and have a look down the hose and you should see the fuel being pumped into the filler. I think you need to put the filler hoses back to standard to get the sub tank to work first.
Did you just convert to diesel and trying to use a high flow pump causing your filling concerns in the first place by any chance??

Thanks Chris,
Sorry it wasn't an egine conversion just the body. The egine is a 4.8 petrol and I think you are on the money with the sub tank system filling in the main hose. There is a fifth hose in there behind the filler caps and my immediate thought is that the same hose that Robin highlighted and if so then the fuel is just going around in a circle. I will investigate this tomorrow when its light.
Thanks to both you and Robin
Kind regards
