Is it the pump or the regulator? I know seems like a stupid ? but I've never had a problem with a pump before.I'm assuming it is the pump and the regulator keeps it at the pressure it needs to be at??? Thanx but,excuse the stupidity,lol.

 

As Dave says ( Storage Wars), Yeeeeeeeppppppppppp you got it right. If theyare working correctly an old inline fuel filter,( dtivers side attached to frame can keep pressure down. It has to be pretty well clogged though.

 

the pump makes the flow and presure and the regulator limits it. if you have an older truck with the reg outside of the tank (alott of the old tbi engine had it on top with the injectors like the jeep 2.5) you can plug the return and just key it on and see what you have for pressure. you could even start it but it won't run well. also remember the lines are old and going up to 80+ psi all at once could bust a line.if the pressure is good then take off the supply hose run it in a bucket and jumper the relay and see what kind of fuel flow you have. if it's slow (it should be a steady stream but there is no reall spec for most cars unless it's diesel) then you could have a filter that's plugged.
normally though it would look kinda like a garden hose with no nozzle on it. should be a strong stream.

 

Ok thanx guys.I recently changed the in-line filter on the frame.I'm having the pressure checked now.Guess If all is well I can check the filter on the pump inside the tank...Will leave a note when I get it figured out..Again,TY.

 

if you're looking for an exact numerical specification as in PSI, it should be 39 PSI +/-6 PSI for All Magnum engines (1992-later)

 

Your right for the number but not all year Magnums had the same pressure.

1992 would fit under the 93.


1993 Dodge Dakota Manual 31psi, 39 with no vacuum.

1995 Dodge Dakota Manual (35-45 psi) at idle.
1995 Dodge Ram Manual (35-45 psi)

1996 Dodge Dakota Manual (49.2 psi ± 5 psi) at idle.
