Regardless of who makes it, it's still going to fail at one point or another.  It is charged with nitrogen and will eventually lose its potency over time.  I installed the Prior Accumulator on one of TGP's.  The throttle body was the biggest problem, but if you remove the fuel lines it would make it much much easier.  Make sure you replace the o-rings if you take those lines off the fuel rail.  You don't need a fire.

I installed the prior one.  I rotated the engine forward and took the old one out.  Put the prior one in, and used a wrench (1" I think) from the pass side to reach the nut on the back.

I just rotated the engine also when I did mine. Not that difficult at all to do...easier than doing the rear banks plugs and wires if you ask me... 8)

Yeah, any accumulator is going to fail eventually.  I just figure I will get one that is the same size as the original and has the "nut" on the front of it.  It should be easier to install as well.  But I've also heard that the GM one cycles less often (like 5 pedal presses instead of 3 or so for the prior).  But just the size difference and where the nut is is enough for me to want the GM one, even if it functions exactly the same.  But, if you don't care about the size or the slightly harder installation, then the prior should work just fine.

I know what you mean.  I had a hard time getting that Prior accumulator in there and tight on the MC.  I have the Prior in my old TGP and brand new Delco on the below 40K TGP, and I honestly say they act identical to me.  I get 3 pedal presses regularly with both cars.  And I think there is an internal leak on the old one.

I think what's most important is making sure there is no air in the system and the fluid level is correct.

yea, my accumulator is bad, 3 pedal presses, the accumulator comes on, no brakes, lol so for slightly harder install for $150 less, i think ill go with prior

The accumululator never comes on, but it keeps the pump fully charged at some rediculous pressure, somewhere near 1500 psi.  If you are steadily getting three pedal presses with no ABS flashing lights, then you are most likely ok.  Depressurize your system with 40 pedal presses with the car off, then turn on the key, listen to it run.  If it goes for more than a minute, you have another problem.  When it stops, press the pedal slowly and evenly, listen to how many presses before you hear the pump motor run.  3 or more is good.

well, ok, it might not be bad then?? it seems like it is, it will run after 3 presses, the brake light comes on, no brakes for like 4-9 seconds and then t he brake light will go off and it will be just fine

mabye i just have bad brakes, they are rusty, and old, and the car has been sitting, and is in dire need of all its fluids flushed, so we'll see, i dont wanna buy an accumulator if i dont have to, this cars strange, u have all these problems that u say happends to EVERY TGP, but my Xover is perfectly fine, keyless works fine, brakes dont seem like the normal problems, i think it just needs new pads and calipers or somthing
