Jim:
Here is a suitable electric pump that will lift fuel from underground tanks [1]. It is 12 Volts DC, Facet Duralift pump , Facet part #40223 / Carrier part # 30-01108-01 SV (available from Carrier Transcold dealers.) They are typically used for commercial truck refrigerators. This pump is self priming to 120 inches (3 meters). Its designed to lift fuel 10 feet straight up.
It is not cheap, at an average price of $125 from the dealer, but it works. I have one on my ’88 F250 7.3 IDI Diesel to solve fuel delivery problems.
It also has a see-through water/trash separator bowl with a pre screen. Regards, – Tim P.
