Hey fella's...

Got a question for ya's where I need a bit of help or real advise on somethin please....

Got a Aeromotive A1000 fuel pump where it was running good for the first 200-300 k's and then recently while driving it's started making a louder noise as if it's still actually priming while driving. One thing I've noticed is that once it starts making this noise when i'm driving the car, it doesn't feel like it's getting enough fuel cause it feels like it's running on 5 cylinders, etc. The engine is getting enough fuel and that to keep running but if I try to accelerate more it just stutters along and then gives up at some stage and doesn't want to move.

It'll start fine when it's cold though and it'll run for a good 30-40k's and that and then once (my opinion here) it's hot (like after driving the car around for a period of time), it just doesn't want to work properly anymore.

Keen to know if anyone else has had this problem or know of this problem with these fuel pumps?

Last night I was ready to actually rip the pump out, throw it on the ground and take a sledge hammer to it. LOL

Look forward to hearin from anyone that can advise or help out with this guys :P

Can anyone else maybe recommend a replacement for this pump as well maybe?

A couple of hours ago, went and started it since leaving it in the garage from last night.

Started and primed perfectly fine and then once oil temp reached around the 60 mark, it started making the loud noise again.

Hadn't rev'd it or even driven it, had been sittin there for a good 10-15mins warming up.

check voltage at the pump. check for leaks and blockages in the lines and make sure the fuels not getting too hot

Hi

All braided lines and have been tested for blockage and nothing.

How much power ou making? What injectors?

only around about 260hp for now.

can't remember the injectors sorry, around 1000cc though.

Did you just pick a random sub forum to post this in or did you think the question was appropriate to be posted in the rb30 conversion section?

no, it's cause i've actually got a rb30 bottom end buddy :)

1000cc with 260hp? .. wha ..

I had something simalar to this and it was hard to find. Ended up being the pickup was collapsing on itself. When you took it out and looked at it, it looked fine, no blockage. But under load it collapsed and created a blockage.. Just a thought you could check.

As soon as I found it and replaced it, the pump was perfectly quiet.

Interesting... I highly suspect that there's nothing wrong with the pump to the extent to say "its broken, get a new one"... cause it primes ok and starts and feeds fuel to the engine still, etc so i'd say it could be something as small as this maybe.

lol. always something simple.. what sort of ampage does the a1000 pull? ive seen a bosch 044 burn out a 30 amp relay.. (more to do with the poor contact with some aftermarket relay holders melting

not to sure mate.

the pump ended up being f**ked after only running on one relay.

some people who think they have a idea on how to do this shit really have no idea.

now i'm up for a new pump!!!

From what I have seen with A1000 pumps is that they really are a race use only pump, aimed at drag racing where they are only switched on for a few seconds.

From memory they are a reconfigured carburettor pump so origionally designed to run at 7-10PSI, just happens that they are big enough to push 100psi when attached to a EFI reg.

Doesnt help solve the issue I know, but just a heads up for the future.

Same goes for most Yank Pumps (SX, Magna Fuel etc)

A1000 isn't much of a pump... they fail regularly in the US circles (im in the us for the last 5 years).

Look at weldon for a good solid reliable pump.

Any pump combo you get you will need some style controll. staged, pwm etc...

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
