new fuel pump died after 1500 miles

[jkern]

driving along today and my low fuel pressure light came on (5psi). as my sig. reflects i have a JRE dual fuel pump setup that i installed in january and only has 1460 miles on it! I immediataly stopped and checked for leaks and kinked hose and fuel pump operation. finding everything in check and both pumps running i limped home to the shop. a fuel pressure gauge indicated that about 3 psi was indeed the pressure. a volt meter indicated 14 volts at both pumps. after some more trouble shooting and being baptized in diesel i conclude that the pusher pump is only making about 5 psi and the lift pump (stock location) is running, but not moving any fuel at all. so for the time being i have plumbed the pusher pump to the filter inlet and am running with an indicated 5 psi at the post filter port. the filter is new... no pressure drop across it at all. so my question is this... are both pumps bad, what are the chances of that, what is the life expectancy of the Carter electric pumps supplied with this kit, better be more than 1500 miles, and lastly... why can i not just use one 15-20 psi 100gph pusher pump at the tank and totally eliminate the pump on the side of the engine? would this be more simple engineering and maybe less componets to go bad??



Ted, if you are reading this, i'm gonna call ya tomorrow!!

jkern,



I'm very interested in how you make out! Be sure to let us all know what you find and how it comes out!



Good luck to you!!

I too am interested in how this comes out. My 2002 truck is on order so I have been researching all the vendor pusher pump systems and even contacting those who don't advertise selling a pusher pump kit to find out if they are working on a one or a solution for the problem. What type of pusher pump does Ted use? Thought it was a 7psi Carter. Did you also use his fuel line upgrade kits?



You might want to include this in a thread Steve St Laurent (sp?) started asking if anyone using a pusher pump along with the OEM has had any failures, can't remember if it was a pole or not. Think he was tring to gather data to see if a dual type lift pump set-up is the solution to all the problems or not.

Called JRE today, they were very helpful and they and Carter will warrent the pump... just have to send it back to get a new one... no hassle at all... thanks guys!
