Hi gents,

I'm in need of assistance :thumbsup:

having a little problem with fuel pump atm (so I've been told), need answers to the following questions:

- does it die gradually? or just dies and no fuel delivered to the engine?

- what are the symptoms of a faulty fuel pump?

- what's the capacity of the stock fuel pump (ie. liters/hour)

- thinking of replacing with a Walbro GSS342 - 165lt/h ~ 475hp - good choice?

(intentions for the car - no more than 14psi boost - R33 S2)

Thanks in advance.

Ive gone through search a few times (looking at other things) and seen this subject a million times.

1. I can be both. Slowly it can lean out your engine. Or you could be reving out 8,000RPM and it will die, leaning out your engine badly.

2. Some have said that it gets really loud. Others have said fuel pressure drops. Personaly when mine did it. I was running leaner then a Anorexic chick at christmas dinner.

3. I dont know that. Look around on the internet. Its there.

4. That migh almost be too big. Get a Bosch 044 pump or similer. Should be fine for your application.

typically once the brushes wear out, the pump will just stop, but if you hit the tank you can get the brush holder to make contact and get the car running again for a little while.

if it was dropping flow, you would check the power supply to the pump for voltage drop and also check the filter/strainer for blockages.

When I knew it was running rich it was running amazing for the first 5min. Like flying. After that the under bonet temp jumped up to about 80* on the highway... Missing. Exhaust temp light came on. knocking. and then it died.

I also blew out my nice new (like 40,000KM) Hi-Flow cat. Now that its running all good, the honey comb stuff is ratteling around in my exhaust...

Well i aint no expert, but if your car is running lean then you will be seeing white smoke out the back.

White smoke is water, ie; Blown head gasket and its pumping coolant into one of the cylinders. OR, condensation in the exhaust after a cold night.

Black is fuel

Blue is oil.

When it runs lean (like dying fuel pump lean) no smoke is being blown out. And it usually gets very hot, VERY fast.

    • 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
    • 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! 
    • Yeah mate, never miss it.
