So the whole reason i took the 42' to ARB in the first place was to get a 120 litre Brown and Davis sub tank put in. I thought it would be too hard to do it by myself on the shed floor so i got them to install it. Its a massive tank and its a bit of overkill, but there is a bit of a theory to it.
I usually go on 4 day trips so i definitely need more fuel than the 80 litres the stock tank holds. I mainly go 4wding in Victorian high country and there isn't much in the way of fuel! Jerry cans is the obvious answer but i don't really have anywhere to put them.
I hate the idea of them on the roof rack, the 40's are rolly enough as it is, i learnt my lesson with the roof top tent i had on my 80 series. I hated what it did to the body roll and handling of the car, so i want to keep all weight as low as possible.
I didn't want jerry cans in the cab, i hate the smell of diesel and its going to be full enough as it is with all my camping gear. Also a diesel spill/ leaking over everything would be a disaster.
I could have gone a Kaymar rear bumper with swing outs but i really like the look of the original bumper and i love the Toyota spare tyre holder thats mounted to the door, with the Kaymar bar the Toyota tyre holder has to go.
So that left me with a sub tank. I really like the idea of the fuel/weight of it down low, almost like adding extra ballast, and i'll never have to worry about fuel range when camping considering full i can hold 200 litres!
Brown and Davis is an Australian company and they're based out of Bayswater, not too far from where i grew up. I would have rathered have them install it but with Covid making travelling back to Melbourne impossible i got it done in Bairnsdale.
The tank itself fits really well and appears super solid. It shouldn't cause any ground clearance issues and i have no concerns about it getting smashed by rocks, it seems like it would handle it no dramas.
I also chose Brown and Davis as their tank utilizes the same fill up point. LRA tanks wanted to cut a new filler into the side of the car and i didn't want that. I know its got the wrong fuel cap on it!
It does it by using a Y pipe, one side goes to the original tank, the other goes to the sub.
They had to modify the exhaust so it now comes out the side. I call it the sidewinder.
The tank comes with its own gauge and changeover switch, i have them sitting in the roof console at the moment. I'll mount them properly in the console when i stripe the whole thing back and make a switch panel for it..
So everything looked all good when i picked it up and i drove it straight to the nearest servo to fill it up. The way the Y pipe looked it appeared i needed to fill the main tank up first then the overflow should start running into the sub. Well that didn't work and just foamed up and i could't get any diesel into the sub tank.
I thought i must have done something wrong, next i thought i would try using some fuel in the main tank then try and angle the bowser filler towards the sub tank input. Well that sort of worked, but it took about 10 minutes to get about 60L of fuel into it as i had to hold the bowser filler on a crazy angle and at half speed otherwise it would foam up. This definitely wasn't good enough, its advertised to be able to use a high flow filler, i can't even use half speed on a standard filler!
I got the car home and stared at it for a bit and noticed its leaking diesel heavily out of the main hose from the Y adapter to the sub tank. I check the hose clamp and its super loose and i tightened it. It appeared as though it had already been over tightened and was stuffed. I put the next size down hose clamp on it and cranked the s*** out of it but it still couldn't compress it enough to stop the leak. The hose supplied seemed to be too big for the pipe it was mated to.
Also the fuel gauge wasn't working, one minute it would read empty, next minute it would read full then next minute empty again.
Obviously all this isn't good enough! I was pretty disappointed considering i have spent a lot of money there lately. I took it back and was a bit flat about the whole situation.
That was 5 days ago and i gave them a call today to see how they were going. The fuel gauge is fixed, they had wired it incorrectly.
The leaking hose is also fixed, it was the wrong hose and had steel reinforcement in it, it wouldn't clamp down no matter what.
The filler neck Brown and Davis supplied is wrong. Apparently they don't make the filler neck for the tank i ordered any more (they actually don't keep any stock of the tank either, they made my one specially for me as not many people are putting sub tanks into BJ42's these days!) and they thought the one they supplied to us would work.
ARB is now trying to get Brown and Davis to make us the original one or get us the plans so we can have a local guy fabricate one up.
So i'm much happier now, they have been honest with me through the whole setup and as long as it eventually comes back to me working i'll be happy. I don't mind if people make mistakes, as long as they own them and are honest about it it's all good.
They were super helpful with the gearbox work and they charged me a pretty fair price. Hopefully it all gets sorted over the next couple of days.
