Little squirting noise when I try to use primer pump?
 

I'm trying to bleed the injector hard lines, and while pumping, I get a spritzing-like sound. The pump is a new-style Bosch primer, probably less than seven years old. It does not appear to be leaking, but I have been pumping for several minutes and no diesel has come out of the hard lines yet. Is there something wrong, or does this typically take a good while?

Oh, and should I have all five hard lines cracked open at the injectors (how it is right now), or should I do them one at a time? Does it matter?

Fast pumping action = spritzing noise (like air is being pushed through fluid)
Slow pumping action = no spritzing noise

I dont think you can get fuel to the hard lines from that little pump, the lift pump primer will only fill the pump elements and the fuel will then exit the return line.

The only way to bleed the hard lines is to spin the pump with it primed first and then tightening the end nuts as you see liquid fuel exit.

tighten and start.

Your expectations are a bit unrealistic. But, for the good news, the sound you are hearing is likely the IP relief valve operating as designed.

Dont even bother cracking the hard lines unless its horribly airlocked.

Just leave em tight and pump up the primer pump until you can feel fuel moving and it gets harder to pump. Then hop in, throttle to the floor ,and crank. Should pop off and even out after some smoke and randomness

OK, so you're saying that I should be spinning the little black pump to get fuel through the hard lines? Is this correct?
What do you mean?

umm - spinning the pump means - cranking the engine (it spins the injection pump).

Hm, OK.

Thanks :).

Extended cranking, pedal to the floor = VROMM!

Thanks, everyone!

Hmmm sounds like someone didn't take his little red pills this morning :P

If your fuel pressure relief valve is the style that can be serviced, take it apart and stretch the spring to 27mm....will help with idling.

I took my allergy meds. I also got a sunburn today because I told my mom that I didn't need sunscreen. Ha. :rolleyes:

Why would I do the thing with the spring? My idle is happy.

X2; The Fuel Supply/Lift Pump and the Hand Primer cannot create enough pressure to open the Deliver Valves in the Elements of the Fuel Injection pump.

And, even if they could the Plungers in the Elements would have to have be low enough to open Feed Hole in the Elements.

The only time the element Plungers have all of the Fuel Feed Holes open is when they are in the shutoff position.

Your right, your car is very happy...I remember the photo of the rainbows, flowers and happy faces coming out of the tail pipe :D

It's just a normal maintenance thing, that the fsm recommends doing every so often....mine was like 8mm to short....gives more power also, as it allows the correct pressure to build up int he injection pump
