Hey guys

I get some sort of fuel cut when i dump it around corners it splutters then its off again.

What do you reckon?

When in a straight line its ok but sometimes does it between gears when my petrol tank is under half full!

Got a new fuel pump installed not long ago maybe its come off the bracket and now sideways in my tank?????????

Dont know what else it could be......

cheers

polly because the shape of the fuel tank in skylines, I heared from the compliencer that skyline fuel tanks are kidney shaped one primary and sencondary next to it(or similar) so when fuel is low or cornering hard the fuel moves to one side away from the fuel pump then you get fuel surge... and looses heaps of power! :D

It happend to be once when I was running very low on fuel with lights on in fact I thought I blew some thing but then when I filled her up all went fine!

so I presume that shape of fuel tank is the cause... or perhaps you said fuel pump is out of bracket!

cheers

Joe

definately sounds like a fuel problem.

I had the exact same problem, except it didnt matter about corners or how much petrol was in the tank.

Barrie discovered the pump was breaking down, and fixed it, yours is most probably like you say, the pump has come off, or you have some crap in the tank blocking the pickup or something.

hmmm, delving into the petrol tank, not a nice job.

What pump is it? new or secondhand?

I think it's time to fit a surge tank. Use the old pump to take fuel to the surge tank and the bigger unit to the injectors. This will also make it easier for future upgrades cos you know the fuel set up is ok.

It ain't as expensive as it sounds but takes some thinking out.

Whats ya feul pressure running at?

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.

      I always use my Karcher, but it's only a little one that I picked up from Supercheap  The only issue I ever had with a pressure washer was when I was a kid cleaning coaches, they had a hi-po industrial sized petrol jobbie that would strip paint if you got to close I saying this, we have a fairly high power washer at work with a diesel powered heater that sprays water at about 60°c, it works great for removing old wax and road grime on the underbody after some foam cannon action, albeit from a "stand off" distance of a few feet

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!

      Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.
