So my fuel sender unit is acting up. I fill up the tank and the needle doesn't always move up right away. Needle also bounces up an down randomly. I was able to find an oem fuel sender unit but wanted to replace the whole fuel pump/filter while Im in there. I am at 205K and would rather just do it now for good measure. I just Cant find an OEM fuel pump! Rockauto no longer offers the denso replacement. What is everyone doing for fuel pumps?
 
Denso's Fuel Pump division got bought by Aisan (Not Aisin) Most people advertising Denso pumps haven't updated their website and if they have them listed as available, they'll most certainly tell you out-of-stock upon ordering. One guy here retrofitted a Tundra fuel pump to work but I don't know what year or era.
Look for an Aisan unit OR (and people will have differing opinions on this) do what I did and get a delphi unit from rock auto. I have about 5000 miles on mine with no issues yet, others have reported acceptable results as well.
 
Here’s the Tundra fuel pump referenced above.
