I have a 1991 Toyota pickup with the 2.4L engine. It would start and idle but would bog when accelerating to about 30 mph and then cruise okay. The fuel pressure was at 10psi vs the usual 50psi. I installed a new Toyota brand fuel regulator and fuel filter, but that did not help. I brought a new fuel pump and then Found the issue at the old fuel pump, the rubber hose from the pump that attaches to the metal line on the fuel pump came off, which I thought was due to a loose hose clamp. I decided to install the new fuel pump with a better hose clamp and all was well for about 2 months when the same bog issue returned. The rubber hose came/blew off again. What would cause the rubber line to blow off? Thanks in advance...
