1990 Dakota 3.9 fuel pump pressure is 10 during cranking and 0 when you let off. Book says 14.5 during running so I need a new fuel pump. Trouble is when I can find info on pumps from vendors they are saying 12 which is not enough either. Any one have a brand and part number to recommend, this is frustrating.

 

*shrug* I've got a Bosch 69306 in my 1988 - have you checked the listings at RockAuto yet?

i put the denso in mine not long ago. works great. cant recall a part# but it might be listed on rockauto

 

So I put a Bosch in with a new sock and it seems to run OK. New hose to the throttle body and new filter. Pulled the box which took only 45 minutes by myself and a engine hoist. I feel I still have a problem at the fuel injectors as I added 20 psig to the supply hose from the disconnected side of the pump back to the TB and it bled down to 12 ish and then over a minute dropped to 0. Like I said at least if feels ok driving now but the top end speed seems a little lacking. Again probably the injectors not working quite right. Put some cleaner in and will see what happens. I did find a corroded wire to the speed sensor for the differential by the frame rail that I repaired.
