the car just got tuned on 4/3/13 (midly built LS/vtec turbo,430 hp,) and yesterday i took my car out for a drive to get some food and got on it a bit on the way, when i got to the drive through i noticed my car was idling really lean and wanted to die, i pulled in a parking spot an opened the hood and the fuel feed between the rail and filter was collapsed and twisted and pouring out fuel. My fuel set up is a walbro 255, stock hard lines to the fire wall in the bay then a compression fitting on hard line to 6AN fittings and a jegs inline filter (which sucks, my tuner took the screen out because it was restrictive) then to a earls nylon fuel line to the fuel rail, golden eagle fuel rail. ID1000cc injectors, areomotive FPR. the line comming from the filter to the rail had a slight curve to it before this happend and was fine when on they dyno, the line collapsed right at that curve but its not like i ever had the line kinked or any thing.

Has any one ever had this happen? what could be the cause of this?
Here you can see how it bent and twisted itself, it was a gradual curve before this happend.

 

Looks like you had a tight bend on it to begin with. Bends have to be a smooth radius on these lines

 

I just picked up some SS braided line and a 90. Should I move the filter to the rail and run a 90 off of it then a hose from there to the fitting on the hard line?

 

Or just keep as is and make the line longer with so it has a smoother bend? I don't want it to go too far out over the trans for track purposes, not sure if techs would pass me with it being over the trans?

 

Any pics before it collapsed?

 

Either way would work, imo I would keep the filter in the stock position (really no point in going with an inline filter other than looks) and make sure you have a smooth bend in the line.

 

I have one but it's hard to see with out zooming in. I don't have a good pic of it at this angle but Youmight be able too see
Just view it full size and zoom in by the dizzy I know it's kind of hard to see sorry

 

It look like the way it was routed might be the problem, i think the 90* fitting off the rail might clear things up attached to the filter.

 

Heres mine with the exact same products, havent ran it yet so not sure if its perfect but seems pretty smooth. Although its longer than i would like.

 

And you just put your filter on that 90 off the rail?

 

Also since my tuner took the screen out of the filter is there any point to run one because its not really filtering anything just being there with no screen

 

looks like the lin is to long causing it to kink. shorten the line up to the filter body. You can ditch the filter body BUT you SHOULD just get a proper filter for the setup

 

Yeah a 90* off the rail connected right to the filter..


It always made sence to me to get a 10 micron inline filter as opposed to the normal 30 micron (the OE filter is 30 microns also i believe?)

So that way the walbro pump is around 32 microns in the tank, then 10 microns at the inline filter, then 7 microns at the injectors themselves.

Kinda got me thinking if mine will kink now

 

Yeah this jegs one sucks so bad it's a 40 micron. I put the screen back in and made a new line today

 

What type of fuel are you running?

 

should have a 90 at the other end of your rail and shorten that line up. maybe even a 120 fitting. i think on the end of mine i have a 120 degree so it turns back toward the manifold a bit

 

93 pump

 

if you look at the outer braid it looks like you twisted the hose when fitting it
and when it got warm it then colapsed

slowly undo one end and see if the twist comes out of the line

 

Looks like you had a tight bend on it to begin with.
