Here's a nutshell explanation

Correct Fuel Hose Installation

Here in the 'States at least if you go into your local auto parts shop and ask for "fuel injection hose". It's ubiquitous; non-exotic. You'll be getting R9 hose....and will be good to go. Just take a peek at the markings to make sure the guy didn't cut from the wrong roll

Gotta have the right size!

I've never had a problem simply buying and using 5/16"


I'll have to go back and figure out what the question was. I'm playing catch-up here !

It seems like the correct one, yes. I'd have to do some part number cross-referencing to 100% verify.

As far as the regulator and making sure I had the left hand, drivers or return side, I think I found it. Most listings don't seem to specify. Maybe not all vehicles have the double st up, not sure why, but it leaves ya a little insecure. So, here and there I would see it stated "right", "left" or "return" so I just started following those clues. It seems the Lucas EAC4864 is the FPR for the outlet or LH side and the site below provided me the Bosch equivalent. Which (I think!) is 0280160214... Fingers crossed. I went and ordered it.

Thanks Doug. As far as we are concerned then, R6 is definitely NOT the hpse to use, according to this:
SAE 30R6 hoses are designed for low-pressure applications like carburetors. These can also be used as an emissions hose.

SAE 30R7 hoses are designed for fuel. These can go under the hood and are typically used for low-pressure applications. SAE 30R9 hoses are designed for high-pressure applications like fuel injection and oil. These are designed to stand up to the environment under the hood.

 

JJJ
Just make sure the FPR has the correct pressure rating. Don't chance it, be 100% sure before you buy. An FPR can fit, but not be the correct pressure rating.

 

"2.5 BAR" (about 37 lbs/sq in) for a pressure rating is all that i could find with this particular Bosch FPR Part # 0280160214...

And yes,,, for the line,,, the 30R9 is rated for higher temps.

 

That pressure is fine.

 

or you could do it better than all said!!

new hi volume fuel filter and fuel pump stainless steel flex lines ,Aeroquip lines and high pressure fittings(rated 1000psi ) ,should do the trick ,and last for rest of your life!

adjustable FPR , you set to run any injector combo pressure, fine tuning!

nothing is to good for my baby,LOL.

 

I bought these:


Jaguar XJ-S V-12 Fuel Hose Kit - 03-2650

 

Jason,

My OLD Bosch info has that .......214 (2.5bar) FPR OUTLET SIDE for P Digital up to 8/89, AUST, and .........508 (??bar) for 9/89 onwards.

I reckon that date is the Marelli change over.

 

I have just done all the fuel hoses I can find under the bonnet
.About 17 of them
I used some 8mm fuel injector hose, came in a box 5 meters
The hose is good for 685KPA with a burst pressure of 6205KPA so I am told
I also used some EFI hose clips, 34 of them
EFI hose clips don’t bight in to the hose and were recommended for the job
I read a discussion on a forum somewhere about replacing fuel lines, there was some discussion about using hose clips, some thought they weren’t necessary
Someone also said if the hose is cheap, it’s the wrong hose, I think the hose cost me about AU$70
Where the rubber hose has a crimp on the rubber to the steel hose, I ground down the side of the crimp in two places, just down to the rubber 180deg apart, then tore the crimp off with a pair of pliers.
hopefully i have done them right

 

Assuming you have a "HE" V12 with the barbed nipples the clips are not needed. The hoses simply press on over the barbs. But this has been debated before. No need in going into again; lots of archived discussion if you're interested

Not sure what year/type V12 you're working on. On the 80s-early 90s vintage HE variants there are no crimped or swaged fuel hoses in the engine bay. The hoses are a press-on type of thing. What you ground down and peeled away is just a collar or 'ferrule'. The purpose of the ferrules is to keep the ends of the hoses from splitting.

Doug
That is sort of true; but as I remember 9could ne wrong) on my car those "Ferrules" were solidly attached at the threaded end of the fitting, in as much as they were somehow crimped at that end into an annular indent in the fitting; sort of U shaped on cross section with a hole in the bottom of the U that was located into an indent. So to remove them the metal ferrule had to be cut and prised apart. I do not think it could be just pulled off, even with no rubber hose there. Open to correction, as always, retirement memory being what it is...

 

Your memory is fine.

On the injectors the ferrules will just drop off once the hose is removed. On the feed and return lines they won't; they are crimped (or similar) to the pipes

But what I'm trying to say....but not very well....is that the fuel hoses themselves are not crimped on.

I've attached some pics

The first two pics show original lines. Notice that the collars/ferrules have no tool marks; no crimping of the hoses.

Next is a pic of aftermarket/'rebuilt' hoses from V12 performance. They decided to crimp the hoses into place; the crimping/tool marks are clearly visible even if the pic itself ain't so great

Last pic is one of my own fuel pipes; hoses simply pressed-on and using the same (smaller) ferrule as used on the injectors.

Well, the pics didn't come out in exactly the order I wanted...but you'll figure it out !

Hey GRANT!!!

OK... Now I'm confused as hell. Well, kinda. I been looking into the 508 and cnat find much. Are you thinking I have the wrong part? THis is what (one of few things) I came up with. Then, I saw a few pictures and structurally they look like different parts. What gives?

Notice in this link they kinda attach this part to coupes and for the 508 to coupes 86-89, specifically (not sure why). Remember, I have a convertible - which I doubt makes a difference in this convo.

BOSCH Fuel Pressure Control Valve/Regulator 0 280 160 508 for JAGUAR XJ Coupe 5.3 H.E.

 

Got it Doug. All agreed and clear. I was writing about the fuel lines, you about the injector hoses.

 

My mistake, I was recently in the trunk and recall those being crimped and my replaced ones are, so I guessed the rest of the engine bay was the same. You can easily take your hoses to a hydraulic shop, who will replace and crimp the ferrules for similar cost to buying the stuff online, just without waiting on shipping.

I replaced my small stuff with Gates Barriacde 225 psi 5/16. Hydraulic shop stuff is Goodyear I think, overkill on the pressure rating.
