Gazzar Posted December 14, 2018 Share Posted December 14, 2018 It's a bit of a long shot, but does anyone know if there is an in-tank fuel pump that bolts into the old bolt-in fuel tank sender hole in a series tank? And dumb question, maybe, would such a pump have a gauge sender built in? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted December 15, 2018 Share Posted December 15, 2018 I have a feeling it's the wrong number of bolts/screws but early Range Rover / Disco / 110 / 130 (rear-mounted steel tank) types are your best bet, but they don't have senders built in.

Gazzar Posted December 15, 2018 Author Share Posted December 15, 2018 Thanks, thought so. Back to plan A. External pump, but with a lot of baffles in the tanks to avoid a swirl pot. G. Quote Link to comment Share on other sites More sharing options...
neil110 Posted January 27, 2019 Share Posted January 27, 2019 A bit behind the times, as ever, but there is a possibility. There is an underseat tank originally intended for use as an additional tank on the 110 CSW. Same size and style as series. Has in tank pump and a sender, seperate units though. The part Nos are: tank NTC2110 https://www.brit-car.co.uk/product.php/88714/0/fuel_tank_under_seat_110_def__s111 sender unit PRC3098 https://www.brit-car.co.uk/product.php/424927/0/sender_unit_extra_fuel_tank_county_station_wagon___defender in tank pump PRC7019 https://www.brit-car.co.uk/product.php/89863/0/in_tank_electric_fuel_pump___90_defender Quote Link to comment Share on other sites More sharing options...
lo-fi Posted January 28, 2019 Share Posted January 28, 2019 Why not choose an in tank pump that fits through t'hole, then cut and shut the series sender top onto it? Pipe cut then braze would leave no swarf inside and make a solid joint. Might just need a little adaptor turned up. Or there are aftermarket pumps that take an AN fitting that might suit. Again, braze an adaptor on the series sender. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 28, 2019 Share Posted January 28, 2019 There certainly appears to be enough room in the top plate of the sender for a pipe to be brazed/soldered in place. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted January 28, 2019 Share Posted January 28, 2019 Alternatively, if the pump above is a good length, then de-weld the series sender from it and re-weld to the pump ? Quote Link to comment Share on other sites More sharing options...
Gazzar Posted January 31, 2019 Author Share Posted January 31, 2019 I think I'll do something similar. The late LWB rear tank sender also has the pickup pipe. It was retained by a locking collar, and the mounting flange is about 5mm smaller diameter than the old SWB unit. I'll get one of those, and add the pump from the RRC unit. I'll drill the 6 holes, if there's enough to cover the mount, if not, I'll use the flange from a broken sender as a collar. It should seal fine. The only challenge is getting the electricity into the pump, how difficult can it be to seal wires in to the top plate? Thanks for the great suggestions, it's really helped spark some ideas.
