As the high capacity filler is way down the back, and as it seems easy to do I am going to slice an identical filler up the front. Well thats the plan as can get the filler plate, neck and bits off another wreck for peanuts.

On the lightweight it was easy as had dual tanks and I fitted a 2.5NA but I see on some defenders the pump is at the tank. Not sure on the 300tdi as haven't pulled it to bits yet.

Pity nothing here thus far has had dual tanks as much better if can get off the shelf, e.g. the spare 90 tank cost me 82 bucks. Not everything is cheap but always good to find off the junk shelf

You might find some useful info in this thread........Single VDO gauge for main and sill tanks

very interesting and very useful as goes through most concepts

- I like the idea of 2 gauges so can see total fuel. Weird what the price for a gauge off ebay is (will be a spare junkyard dash at 43 quid for a new one)
- Liking this forum a lot as I ran some searches on Aux tank and extra tank and nothing really stood out. On most the UK forums if you ask a question some tosser jumps in and says do a search in bright red flashing letters (they must have the post saved for instant re-use). I've always had the attitude help some poor bugger out, he may be daft but it only takes 2 mins. Anyway off my soapbox as wrong section.

Hopefully my manuals will be printed out tomorrow. Lucky as in my mates yard I tinker at we got 1 x 2.5 petrol 90 (in pieces), 1 x 300tdi 90 (in pieces), 1 x 200 tdi 90, 1 x 200 tdi 110 and 1 200tdi 110 (blacklisted). A few Pinzgauers and a couple of TD5 Discos (one of them wont start as has an electronic bit malfunction)

regards

Mike

My Holden Overlander has twin petrol tanks. Has an electric solinoid valve to switch tanks. With another switch to alternate fuel gauge from tank to tank. When I bought this car it had a manual switch under the seat. You had to stop and get out to change tanks.

hmmmmmmm always great to have manuals to ponder over whilst waiting for the car to arrive so you can plot and plan. Just need to print out the parts manual an military servicing schedule

Found these piccies but in reality I never seen one of these change over taps anywhere. The schematic is good, though.

I had that idea valves with the leavers probably wouldn't have looked that good

Thats from the 300TDI overhaul manual

The series ones were simpler design, can't figure why fo a td they would split it into three seperate sections with linkages in-between. Most likely why I never seen this valve as would cost a few hundred quid for one.
