Inside fuel tank hoses question

1992 XJ6 Vanden Plas.

I'm replacing the in-tank fuel pump and there are two rubber hoses about 10 inches long each, inside the thank that connect to the pump itself. One is the fuel feed and the other is the fuel return.

Since I'm replacing the pump assembly, I thought it would be a good idea to replace the hoses also. But I've not been able to locate the part number for these. The online store I usually get my parts from did not have anything.

My question is: Are these special higher-grade hoses than what's available at my local auto parts? I wouldn't want to put something that would disintegrate in a couple thousand miles.

The hoses are labeled: C - 04.91 EBC 4678

Any information greatly appreciated.
 
John,

I never got inside the tank on my 1993 XJ6, so I am not familiar with these hoses. Are they just standard looking lines with clamps, or do they have special fittings pressed onto the ends? Check this link at motorcarsltd.com. They offer a few choices for your car. In the interest of cost, I hope that it is the one labelled "Many Uses" at the bottom of the page. It appears to be EFI hose, which I assume would be as resistant to gas on the outside as it is on the inside of the hose... it is all fuel-resistant rubber. Just buy the highest grade you can find so that you aren't tracking down a fuel problem in a year or two.

Use standard fuel hoses that meet fuel injection pressures. Also be very careful about replacing the fuel pump within the module. Jaguar recommends replacing the entire module that contains the fuel pump due to wire terminal heating problems on this configuration. They only supply the module (a bit pricey). You can also find after market pumps only for less. Be careful. I dont like evidence of scorched wiring in a gas tank. A policy that gives a margin of safety is to keep your gas tank at least half full of gasoline most of the time. This will tend to cool the wiring in the tank. I have personally seen this scorched wiring in the module and it is real. Good luck, Jack
