Hey guys just wanted to see if anyone has had this problem with there cefiros

When i get to 1/4 tank left in my car it starts acting like shit

spluttering, poor acceleration and just generally runs like poo

I fill up the tank and straight away its fine again

was think it could either be

1. Dirty muddy crap in the bottom of fuel tank

2. My fuel pump is spittin the dummy and cant maitain pressure with less than 1/4 tank

3. its just my imagination and its not really happening

let us know what you guys think, or let me know if you have had similar problems

thanks

yeah i think i got the same here - its not the fuel pump (nippon denso 600hp) but when i go around corners on 1/3 tank it does what you have described. i was thinking of a surge tank but i would rather fix the prioblem - could be crap in the bottom.

interested to find out if anyone has fixed this problem

Odds are it is just surging, it may have something to do with the position of the fuel pump inside the tank that is causing "pick up" issues under 1/3 or 1.4 tank.......

Easiest way to fi the problem s to keep it above half :)

My car never see's under half as it starts to surge at about 1/3 (this is whilst on the track drifting though, i don't drive it on the street so i can't comment on that)

PS: I have recently fitted a new tank (clean) and new pump so my surging is not caused by crap in the bottom.

Well i got adventurious last night and decided to pop the pump and everything out

low and behold was a fist full of dirt floating in my fuel tank.

Someone obviously didnt like the previous owner in japan

i ended up having to drop the whole tank out and scrub the whole inside of the tank as it was full of mud and rust

it still aint perfect so im going to have to look for a new tank eventually

but for the moment it is alot better and actually runs normally below 1/4 tank

I believe the R32 and S13 fuel tanks are the same.......you just need to change the fuel filler neck.

Hope that helps you find one. (make sure you take dimensions etc before you buy to ensure i am correct.......i COULD be wrong, it has been known to happen, sometimes lol)

Thanks for that man

Hopefully the S13 at the wreckers tank is in alright condition

is good to be able to finally drive my car on the limit without it shittin up on me

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
