Saltwaterjunk Posted May 24, 2015 Share Posted May 24, 2015 Hi all, I recently bought me a 1978 LHD 109, 2.6 six cylinder petrol engine, that was equiped with an LPG system. The LPG tank is in the place where normally the fuel tank would be, and a second, smaller tank is now fitted under the right front seat, with the filler opening under the seat. Now, I am removing the LPG system and will need to remove the LPG tank too. That will create the opportunity to either refit an original tank or do something else. What would be your ideas and tips on creating fuel tanks and the like? Now, if anybody has a spare 109 tank in good nick laying around, let me know. ;-) BR Harald Quote Link to comment Share on other sites More sharing options...
secondjeremy Posted May 30, 2015 Share Posted May 30, 2015 Make sure you've done any welding necessary around the rear of the chassis before fitting the tank! Quote Link to comment Share on other sites More sharing options...
Gazzar Posted May 30, 2015 Share Posted May 30, 2015 I wonder if one of the modern plastic tanks would fit? Disco or defener? Bloody metal tanks rust too damn fast. With an "in tank" pump? I presume you have a rear filler on the tub, or you'd have the under seat tank with a proper nozzle. Would you think of running a twin tank system? Are you keeping the 6 cyl? G.

David Sparkes Posted May 30, 2015 Share Posted May 30, 2015 .. either refit an original tank or do something else. What would be your ideas and tips on creating fuel tanks and the like? This is from a couple of threads on the forum of the Series 2 Club, I haven't done the work myself, there were no pictures, just the link to a Parts Listing which shows all the parts associated with the tank, including the replacement outrigger. Direct quotes from the S2C posts are in italics. Listed under "DEFENDER 1987-2006", ESR4132 is a 110/130 Auxiliary Tank (NTC2089 became ESR4132). The capacity is 15 UK Gallons (68 litres), instead of the standard 10 UK Gallons. It is an underseat tank designed to connect to a side filler, rather than the 'military' underseat filler. It is an easy fit, have to remove front tank outrigger, the 110 outrigger is a bolt on job. It was stated that you have to create a couple of brackets on the chassis to bolt the outrigger to; these were not detailed. In the case of the original S2C poster, he had picked up a tank cheaply from a UK Ebay advert in Dec 2013. Hope This Helps. Quote Link to comment Share on other sites More sharing options...
xychix Posted May 31, 2015 Share Posted May 31, 2015 My 109 series III has 3 tanks (was used for overlanding) 1 in the back (in use) and 2 under the seats with fillers under the seats, not in use.... will refurbish them one day. Can make pictures begin juli if you are still looking for info by then. Quote Link to comment Share on other sites More sharing options...
Snagger Posted June 14, 2015 Share Posted June 14, 2015 I have the same set up as xychix - I reused the original 18IGal rear tank and added two ex MoD 12IGal front tanks (under-seat fill as I didn't want to cut the body, have exposed piping inside the car, encourage fuel theives or face overzealous customs staff on border crossings). The tanks do get weepy around the welds with age, but at over 40 yrs old, they're still going strong. A coat of the POR15 treatment inside would be useful at some point to stop the fuel sweating out through any porous welds, which in turn would stop the exterior waxoil/Schutz being washed off.

HoggyN Posted July 4, 2015 Share Posted July 4, 2015 If the OP is still around, I may have a usable spare 109 rear tank. It's been lying around a while though so I'll need to check it's condition. Quote Link to comment Share on other sites More sharing options...
xychix Posted July 4, 2015 Share Posted July 4, 2015 does OP still need pictures ? Quote Link to comment Share on other sites More sharing options...
John Carden Posted May 8, 2021 Share Posted May 8, 2021 Hi looking for help on refuelling my 109. Evey time I fill her I start to lose fuel from the top of the tank, but only when full. Is there a valve or something at the top of the tank ?? Quote Link to comment Share on other sites More sharing options...
western Posted May 8, 2021 Share Posted May 8, 2021 Might be a breather pipe or hose that has corroded or split, Quote Link to comment Share on other sites More sharing options...
Snagger Posted May 9, 2021 Share Posted May 9, 2021 It could be a loose hose fitting, perished sender gasket, loose sender retaining ring or a hole in a pipe or hose. There is no way to know without direct viewing. There should be some access panels in the tub floor (deleted on Defenders, but LR were more sensible on the older vehicles).

FridgeFreezer Posted May 9, 2021 Share Posted May 9, 2021 In addition to the above - I've had problems in Europe with E85 petrol eating the cork seal in the top of the fuel tank, ended up having to fill with E5 (premium) at vast expense Quote Link to comment Share on other sites More sharing options...
