Thread: Series 3 Auxilliary Tank

Thanks for the information.I picked up a good tub with the two fullers so I thought another tank can be used. Just needs the front bracket to fit, easy job Cheers Bill

See my post below (Nov 11th) to see what this looks like.

G'Day once again folks,

Well, the fuel tank installation got its commissioning test over Christmas with a run south of Adelaide over to Kangaroo Island towing our camper trailer. The run down was on a pretty hot day (35 degrees C) but all went well except for what I suspect was vapour lock that occurred after a lunch stop about half way to Cape Jervis. We were running on the new tank, and when re-started after about a 15 minute stop the engine would start but wouldn't get much above idle with much coughing and farting about. I switched to the full main tank and after a few seconds the problem cleared, and I was able to switch back to the auxiliary tank after a few minutes driving with no further problems. At Cape Jervis I felt the auxiliary tank and compared it with the main tank and noted that it was quite a lot warmer, I guess due to it being in the airflow from the exhaust manifold. I expect this problem will only occur after the fuel system gets heat soaked, such as after a stop on a warm day. It was great having the extra range, especially with the price of fuel on the Island.
Thanks again for all your help,
Cheers,

Coop

Just a bit of lateral thinking if ever the heat thing was a problem say on a northern trip. Our work nissan have a 'subtank' as they call it and when low you have to pump it across to the main tank with a switch and i presume pump. Not sure the logistics but just thought i would mention that where you could set it up to pump across at times to top up the main tank where it could cool? Just a thought anyway and sure it wouldn't be a problem anyway.

THanks for the idea Craig. Will keep that in mind if the problem recurs and becomes a nuisance.
