Mason Engineering, J-Shaped Hose to FPR

[beniloa]

Got the Mason Engineering fuel line kit for my 1984 911 3.2, especially since the engine is currently out.

Everything is pretty self explanatory... except for the small "J" shaped hose that connects to the FPR (fuel pressure regulator).

I know it says to trim it a little in the instructions, but I'm not feeling like its going to make much of a difference since the bend is so severe.

What have other done with the same kit?

Photos would be appreciated.

Tried to contact Mason Engineering, but their website was down. Also tried to message him through here and on Instagram.






Was also thinking maybe my bracket got a little bent sometime between 1984 and now, so I thought I'd share this angle of it:

Well, that won't work. The proper hose has a preformed curve.

Guess I’m gonna have to do the 270degree hose trick…?

[john walker's workshop]

Good trick.

Put a coil spring inside the hose so when you do the tight bend it won't collapse.

[A930Rocket]

Good idea.

Is that preformed line not available anywhere?

Your bracket looks very bent to me- I need to go look at mine…. The hose takes a sharp turn, but it’s not THAT sharp of a turn.

Yep- your bracket is pretty twisted. Even mine has a little warp that needs to be fixed. Straighten it out, and things should go a lot easier for you. Take your hose to a REAL hardware store that has a selection of small springs and find a long one that is sufficiently stout that fits good and snug inside the hose- that will eliminate kinks, as mentioned above.

Also- would you mind posting pics of your other new hoses- I am considering these for my replacements. Thanks.

Or on the outside…

Just making sure: this bracket in your photos is out of your ‘85 as well?

Will post fuel lines later today.

[85RedCarrera]

Yea, it is out of my ‘85.

Mason's kit itself is quality, but I'm stumped on that short hose. I went ahead and gently bent the bracket back, which didn't make any difference for the short J-hose situation.



If I were to do it all over again, I would go with Len Cummings' kit. Support for Mason Engineering seems no where to be found. Website is still down, they do not reply to DM's on IG, and cant seem to find a email for them online either. Only reason I bought this kit myself is that I got a decent discount on it at the time.






Here are the tunnel line part of the kit.



You can also see a photo of a finished intake assembly with the Mason kit here, which you likely already saw:

Thanks for posting the pics- the hose crimp on the Mason "J" hose is much longer than the factory piece- that may be making things worse, as well.

Any update on how you made out with the short FPR line?

In the midst of the install now and encountering the same problem. Did the spring in/outside of the hose help in the end?

SkunkWorks,

I was having coffee this morning when I read your post and decided to do a quick test. Picked a couple of hard rubber fuel hoses from my fuel hoses scrap box and began my investigation.



You don’t need an internal or external coil to keep the cross-section from collapsing based from the test. The U-bend needs more stress than a J-bend and demonstrated how I would fix the problem.

Sorry guys, did not realize there were questions from this slightly older post.

I ended up buying the short pre-bent line from Griffiths. I had to bite the bullet on costs but felt better about it in the end.

I am still boggled as to how someone can put that short Mason line to use.

[A930Rocket]

Is that some kind of special fuel line? How did it bend without springing back?
