im guessing its something like a bosch or something and cant pick up right from the bottom, i had to change my pump (stock) to and 040 (my decision) kinda overkill atm cause im not pushing tones of power but it sounds like that could be happening to you,

but i guess others can help out more, you prob need to find out what pump you have

Cheers matt i axualy have about 500-510 hp at the wheels so im thinkn there might be some upgrade on the pump ( not shaw if a stock one could pump that hp out ) if it does come down to being that problem i might have to upgrade...

doubt stock could.... if its only happening when its getting below 1/4 then just fill up earlier, i can run under a 1/4 but i dont have anything to monitor what my fuels doing, running lean ect, also it depends how low the pump is mounted, i think its best to find out what you have... cause without knowing exactly it could be something else. if you compare stock, or walbro pumps vs something like a bosch you can see why it cant pick up fuel low in the tank

Thanks mate i do fill up earlier now but being my daily driver im goin to the petrol station twice a week...now i know others dont have the same problem with the fuel i know it must be something to do with the car or the pump....

Your fuel gauge is f**ked.

If you're getting near on 500ks out of a tank, even going light on the wellie, you're doing very well and likely running the tank just about dry. My 33 on 98 would struggle to get 400 and my Stag on 98 gets ~430.

The fact you're on E85 means you're potentially using up to 30% more fuel than you would on 98 meaning you're running the equivalent of about 600ks from a tank. Your car is magical. There's a leprechaun under bonnet and he's pissing E85 into your intake.

Readjust your brain to accept that 1/4 = empty and you'll be right.

just to clear it up im on 98 not 85,

also what the above guy said could be right too, i didnt realise you were making that many kms per tank as is, my car untuned with the 040 is getting 360-380 per tank, filling up early cant remember what i was getting from a full tank... but the 360ish means about 11.5L/100kms... so yeah i think the post above is right, fuel gauge

Im amazed no one has asked. How many litres do you put in when it is at "1/4"?

Lol 500k's per tank is awesome. All highway i get 400-450. Heavy foot driving, fuel? My car thinks its water haha

true, sorta just noticed he didnt know what the pump was and thought that was the issue, i also didnt realise he was getting an awesome amount of kms to the tank!

      Another little story of weird shit happening

      By MBS206 · Posted

      Ha ha, yeah, I've had one following me around in my parts boxes since about 2007 I believe. Just a little iddy bit hole drilled in the one I have to let it vent out once pressure was removed from the engine side. Still no idea what I'd put it on, ha ha.

      Anybody affected by the M1 minefield this morning?

      By MBS206 · Posted

      Just read this... Just a little bit of a wild one! Do you think the driver was testing out a new feature/device for how to lose the cops in a high speed chase?   I also suspect, if the box has a road sweeper that does magnetic metal pick up, he does a LOT of work in the machining industry. Which is what most of that looked like, machining chips from a mill or lathe. And I bet they're RAZOR sharp! And from an environmental perspective they really do need to actually collect all of those little pieces too. I wonder how many people still cop flat tires over the coming months on that road?   As for insurance company, yeah, it'd be interesting to hear what they say to the owner. But realistically, he's right, that "It's his fault". In the way that, it was his truck that spilled it, so they need to clean it up. However, neither he, nor his insurance company may bear the end cost if they do an investigation and find out it was caused by someone elses negligence (And they know who)...

      Yeah, no matter what bad things people can say about Julian from Autospeed, he at least was capable of thinking and his inclusion of a check/relief valve in the plumbing for the Audi boost controller, that I made a copy of and used for years**, completely eradicated that problem. **It's still lying on my workbench where I put it about, um, 18 years ago and have never found a home for it!

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      I didn't actually know this! I've seen photos of the H1, mainly outside shots, and they just look "different". I guess there'd be a few little changes like nicer rims, and probably the fact they have nicer looking paint with some depth and shine, which will make any vehicles body look different to the very flat colours of the defence force.   I've watched the guys on GHPC convert their Humvee to LS1, and they've done some really nice front shock upgrade. I'm waiting for the next video on it with the rear end done. I can't remember if they've already done it, or I dreamed it, but I believe they're also supercharging theres. They will be in the future doing proper long travel suspension too.   If you ditch out your big V8, as rubbish as it must be, send it to my place. I'll let the unreliable V8 motor and box be here. I just like V8s... So I'll find something to do with it... Even if that something is just taking up valuable space in the yard. I might have something Skyline I can send back in payment... Or even Ford Barra motors  (From memory you're in Canada yeah?) So you can then play with the legendary Aussie 4L version of an RB...  Except they don't have that distinctive random miss at idle like the RB25 does.

      Or you mean the age old problem of early 2000's manual boost tees, where they never let the pressure out of the line between the boost tee, and the waste gate, so after your first trip on boost, the damn wastegate liked to stay open and be laggy on gear change?
