Feed pump died on Power Tech. PT wanted about $80 for replacement. Found an article on the Wanderlodge forum that shows an alternative feed pump with identical specs (and it looks identical). Order off Amazon for less than $40. Seems to be working perfectly. Time will tell as my old one lasted 15 years.
Replacement part number is E8012.

Have the Napa version, been working for years
Here it is on Amazon for $37: Amazon.com: Airtex E8012S Universal Electric Fuel Pump: Automotive (https://www.amazon.com/Airtex-E8012S-Universal-Electric-Fuel/dp/B000DT7Y7A)
Having a spare for $8 delivered is also not a bad idea. OK for diesel: New Fuel Pump Petrol Diesel Low Pressure Universal Inline Electric Pump... (https://www.ebay.com/itm/New-Fuel-Pump-Petrol-Diesel-Low-Pressure-Universal-Inline-Electric-Pump-HEP-02A-/132224092810)
For the PowerTech generators found on GVs, the Facet (Bendix) tube style pumps are OEM and do a good job but cost a little more. Lot of aircraft use them too. See all at Chief Aircraft Parts at: Search results for: 'facet' - Chief Aircraft Inc. (https://www.chiefaircraft.com/catalogsearch/result/?q=facet)
I have had a couple of the square type leak. The tube style have a filter in the bottom (5/8" wrench) that is easily accessible.
