While trying to get to the bottom of some trouble codes and poor idling/engine bogging issues last week, without thinking, I questioned the fuel pressure regulator in my Taurus. I offhandedly said that around my 'assistant' I'll refer to this person as, and while I was gone, they decided to try to replace the FPR
with good intentions. Well, I came back to find out that the fuel line was cut significantly shorter than it was originally, and where it connects to the fuel rail, the line was bent/kinked beyond repair.
To make matters worse, the new setup for the lines was horrible; random scrap hoses and clamps put together on this questionable variable PSI
So, in an effort to get this all back to normal, I tried to get it as close to original as possible ..with some caveats.
I had to buy a replacement hose to connect the FPR
to the fuel rail, and it seems to work so far. Clamps secure it pretty well to the nozzles as necessary.
Where the fuel line comes out of the rest of the fuel system however, it's a mess.
-The fuel line barely comes out of the engine bay
-The fuel line is hard plastic, so squeezing the pressure regulator back in to the line can easily lead to a leak
In an attempt to fix this, here's what I've done today:
I bought the same type of replacement hose that was used to connect the FPR
to the fuel rail. I also bought a 2 pack of Dorman quick connect 5/16" line unions. The line unions basically have the same sized nozzles as the FPR
and fuel rail, but it is longer and serves as a coupler between the lines.
The line unions, I heated up one with a torch to try to spread out the tip of the fuel line. It sort of worked, but I might need to expand the end of the fuel line a little deeper, so the entire line union will fit.
Here's how it's all connected:
The fuel line 'shield'* covers the fuel line. The fuel line attaches to the 5/16" line union. A hose clamp goes over the 'shield', and secures the fuel line to the line union.
The other end of the line union leads to the FPR
; hose clamped.
The other end of the FPR
connects to the fuel rail; both ends hose clamped.
*Not sure if that's what it's called. It's a hose that covers the fuel line, and there's a clip that attached to the engine bay to keep the line in place.
Now, my question is: without replacing the entire fuel line assembly, how can I make sure everything is connected properly and not waiting to pop off while driving?
Link is to the assembly; pulled from rockford auto parts. Is it possible to remove the original fuel line where it comes out from under the car, and put a replacement fuel line in to simplify this?
Really appreciate any advice. My solution might work after tightening some trouble spots, but it was honestly a shot in the dark. First time working with this fuel line.
