Fuel problem

[siteunseen]

Positive is smaller on mine.  Just checked.

I attached another short jumper wire to the large post and ground to the car body. The other jumper to the + on my battery! The pump did not run, swapping the wires and the pump still did not run.

Sounds like your aftermarket pump is shot.

Good work finding your problem. Sounds like you will need a new pump.

It looks like a bosch pump, but the end (not the end with the terminals) seems sharper. Bosch has a radiused end if that makes any sense.

These bosch pumps are originally made for Porches and can delivery 250L/hr and 6.0barg pressure. If you can't find a original type from a wrecking yard than my choice would be a bosch.

Google: " bosch Fuel Pump - 0580254044 " and you will find info on them. They use them a lot in Europe as an aftermarket replacement for all kinds of cars.

Yes, your pump is bad!  Hurray, you found the problem!  Hope it's not too expensive.  But at least it's an easy fix.

 

I recommend a Fram G3 filter installed prior to the intake of the pump, so that it won't get jammed up with rust from the tank.

 

I second Chas' recommendation for a Bosch pump -- quiet, efficient, durable.  Great equipment.

Holy moly!  The OE pumps are $400 now.  I paid $250 for my Bosch a few years ago, now they're Beck Arnely.

Looks like this pump has been on the car for many years. Knowing my dad he would not have spent a lot of money just for a big name brand, i am sure what ever Autozone sold and cheepest. Where do you guys attach the Fram G3 filter, thereis only a very small piece of rubber hose between the pump and steel fuel line.

It goes before the pump.  Between the tank and the pump.

AirTex E8312 from Rock Auto = $60.79. That's what I've been using on my 76 280Z and they work just fine. It is however, very important to install a Fram G3 between the fuel tank and fuel pump as others have mentioned.

 

These newer style pumps use a Ceramic Turbine to push the fuel. They are a lot more sensitive to small dirt particles than the old Vane type OEM pumps. Tolerances in a Turbine style pump are a lot closer than Vane style pumps.

Thank you everyone for the great help, i will get needed parts on order. While i was under there i noticed that the rubber fuel line from the tank and from the pump looked quite sad. I thought it a good idea to replace them, can someone give me the sizes please?

[siteunseen]

I'm pretty sure the hose from the tank to the pump is 3/8" (10mm), and can be the cheaper low pressure fuel hose.  Everything from the output port of the pump is 5/16" (8mm) HIGH PRESSURE for fuel injection, more costly but you've got to have it.  

 

You'll see the difference.
