Gefr, i know i replied to your query on my thread that i never had any issues with voltage drop on the toyota fuel pump retrofitted into the stock assembly on my 990 but now that i think of it, my dual battery setup might have had a hand in this. It might have prevented the loss of pumping capacity when the radiator fan kicked in.....
