hello
what is the proper high pressure fuel line routing for a fuel pump rotated 180 degrees ?

on my car the fuel pump is rotated 180 degrees from original examples.   (pictures)

in some of the examples the high pressure line leaves the pump and is actually clamped to the floor of the car before it is connected to the metal line.

currently the line leaves the pump and floats over the driver side axle, which is probably not the best way to prevent damaging the line.

the pump and cover are installed the way the car came.  there is even an mb zip tie the connects to the protective cover to snug the large low pressure line from the trunk as it is routed around the canister.
i have not tried to rotate the pump and am not sure if i should even try.

thanks in advance for any feedback

I had to replace these lines a couple of years ago; it required removing the fuel pump cage. As I recall it only fits on one way. So, then the hoses can only come out one way...

I didn't like the way it all fit back together, I remember having to move things around a bit in order to get them to all enter/exit properly.

So how is this 180 off?

hi,
the input tube on my car is facing outward (away from the fuel tank) where some of the other photos the input tube is facing the fuel tank.


this may be just the way my car is and i just need to find the best way to route the high volume line from the pump to the metal line.

Matt,
What prevents you from turning the fuel pump / cover, 180 degrees to face the tank or inside of the car?

I would have thought it is easier just to turn this pump rather than trying to route the lines... I did it last winter (I mean I got the lines correct there, togethe with all the hangers, brackets, rtc.). It is good now once and for all. Brackets are available if you need them, hangers too, special bolts as well...

i know this is an old post.

while i had my fuel pump out to re seal i decided i'd take some time to re orient the pump and cover to match the second picture in my original post.

i do know the trunk floor was replaced so maybe when they went to put the fuel pump back in there were no holes so they winged it?

anyway its in and properly oriented now.    8)

hi Rodd,
first i had to rotate the pump bracket to get the pump in the correct orientation.
The car has the later style pump cover so i had to drill 2 holes in the trunk floor and then the 3rd bolt screws into the crossmember.


the earlier style cover would has  2 tabs with holes that align with the cross member for the mounting bolts.

Oh, OK.  I guess it can be blamed on the trunk panel replacement having no pre-drilled holes.  Wouldn't there be a hole in the cross member, waiting to be used?  Regardless, congratulations on your corrective measures.

hi,
yes there is one bolt that goes into the cross member and 2 into the trunk floor.
