im guessing its an aftermarket pump, and when your running low on fuel, the sound of it pumping or buzzing echos more in the emptier tank making it more audiable.

Fuel types arent going to change the sound

Thanks guys. its been like that for awhile now i got no idea on how to get to it either( PUMP) As i was the first owner in australia and it just came like that.

Like i said everytime the tank is full it does this how would i know that this is a aftermarket item or just needs a replacement?

Would be over the moon if it was aftermarket hahaha :(

is it a stocker? only when filling up? does it make that sound when you prime it everytime or just filling up which is quite strange. if it wasnt doing it before then first assumption is its on its last legs.

hopefully someone with more experience can shed some light

Mate i only really notice it when im idle, cant hear it over the exhaust

a dyno will tell you if your fuel pump is not meeting the needs of your air to fuel ratio. otherwise if you start feeling fuel cuts through the rev range i'd start considering a new pump. but if not, you have nothing to worry. :D

    • 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.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
