I want to replace the fuel filter on my 1985 XJ6. The car is in storage so I don't have access to it. Is the original filter a "Push-on" type with clamps or is it threaded. With such high pump output, it seems strange that the filter would just have hose clamps and not a secure threaded connection. Seems a prime location for a devastating fire hazard. I was looking at this filter, listed for an XJ6.

 

I just took a quick look at my 84 series 3 and the filter has push on hoses with hose clamps.

 

Secured with hose clamps. Don't forget to depressurize the fuel system or you may get a spray of gas in the face. AMHIK.

 

two hoses, pull them off and push them on, then tighten the clamps. There are no reported fires from this area.

install the Bosch filter, that's what they came with, it's a pretty hefty canister.

no need to depressurize, just loosen the clamps, slide them away, rotate the filter while holding each hose to unstick them, pull one hose quickly and insert in the new filter, repeat with the other hose, that's it. Just make sure the filter is oriented correctly like the old one.

 

Alright, don't depressurize - just saying I got a facefull of gas when I pulled one end off of mine.

 

if the car has not been running, the fuel pressure will be very low if any, if you went to buy the filter and then came`back to change it, you had pressure and that's why you got splashed!!

 

trying to delete this, where is the delete button?

 

My 2 cents.
Rule of Thumb.
On all EFI systems it is advisable to depressurize the system before disconnecting any lines or hoses.
On the Series 3, there is a one way valve that allows fuel pressure to be maintained. The fuel filter is after the valve.
Given that if a vehicle has been sitting for a while, like in Jose's case, the fuel pressure will eventually bleed down but, BETTER SAFE THAN SORRY.
I replaced all of my fuel hoses on both cars about a year ago. I used high pressure fuel injection hose and band clamps.

 

The safest and most respsonsible answer is to depressurize.

Personally, being a heathen, I loosen one clamp and wrap the joint in an old, big towel, wriggle the hose a bit, and 'depressurize' by letting the gas gradually flow into the towel. Then toss the towel outdoors to dry out.

Don't fully open any joint/fitting/hose or you'll have a real mess on your hands. Just crack it open/loosen it so the fuel will gradually flow out. You'll know when the pressure is gone.

Hi Jose,
Do you have the part number for the correct Bosch fuel filter for an 85 SIII?

 

I got it at CarQuest last February, $12.29

the receipt says: wpc E100029287 BOS

the flap of the filter box says: F 5030

 

FWIW: my notes tell me I used a Bosch 71028 filter, replacing the PO’s Wix 33161.
Hope this helps.

Andrew.

 

Andrew, Thanks for the info, but the Bosch website does not list this as being compatible with the SIII XJ6. Lots of BMw's and Mercedes.

 

The OEM part number for the in-trunk fuel filter for 83-87 XJ6 is 0450905030. Dimensions are 4.25" long x 3.00" diameter.
Bosh has the filter listed as F 5030. Hope this helps.

 

Thanks Sanchez, I'll pick one up.

 

Well, that’s odd. That filter has been in my 87 for more than four years with no problems, so I can at least tell you it does work well in the Series III. Amazon still says it is the right filter, although this Bosch site (https://www.boschautoparts.com/en/auto) offers no fuel filter number at all!

Oh well, consider it another option for you...

Regards,
Andrew.

 

The filter goes by both numbers:

 

looks very similar to the Bosch F 5030.

Check the following listing on eBay UK, enter your car's details.

The Bosch F 5030 is used in many European cars, from Alfa Romeo to Maserati.

It *is* the 5030. Look at the part number printed on the filter.

Andrew.
