Dirty Fuel/tank

[SideWaysChef]

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.

Thanks Riverside

THink that will have to do the job until i can afford a surge tank

just seems like one thing after the other with my car at the moment

but ya get that

Also pull the pump out and check the sock hasnt come off, it adds about 50mm of tube which helps the pump suck from 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
