walbro 450
So i have a question for you guys. Im having some fuel pressure issues with a return style fuel system with a walbro 450. At key on the pump stays steady at 58 psi but when the truck goes under any load say up to 80-100 kpa it lses all fuel pressure down to 20psi. I back probed the wires at the pump and they maintain 13volts the entire time thoughout. So my question is do yall think the pump is bad or clogged? Any suggestions did i get a bad/fake pump?

Have you checked your lines for kinks ? I changed my fuel pump in my Typhoon back in the day and I found that someone previous to me had twisted and kinked the rigid line, it still ran OK on my truck, but I could definitely see an issue on a truck with higher demands.
Also, did you buy the pump from a reputable vendor? Possibly they sent you a mis-represented pump as a Walbro 450.
Just my $0.02
