Hi guys!

Beides getting a new filter and swapping out for the old, is there any further work needed to get it changed over correctly???

And what brand should one go for??


Many thanks!

Chris

 

the original Bosch filter. $12.97 plus Sales Tax.

 

Hi Jose!

Thanks. Ordered and should get to me by saturday!

 

I like to relieve the pressure in the system first by removing the fuel pump relay and cranking for a several seconds.

 

What does removing the relay accomplish?

 

removing the fuel pump relay prevents the pump from running while cranking the engine for a few seconds. Cranking the engine will fire off the fuel injectors and bleed off the fuel pressure.

 

Ok so i remove the filter, take out the relay and hit the accelerator for a couple of seconds??

Thanks again by the way!

 

The idea is to relieve the pressure before removing the filter. Safe and less messy that way. You'll have some spilled fuel no matter how you slice it.

Personally I just loosen one of the hose clamps, wrap the hose and filter in an old towel, and gently wriggle the hose and filter so as to slightly break the connection. The fuel goes into the towel and the towel tossed outdoors to dry. If the connection is opened entirely with the system under pressure the fuel will really spurt out and you'll have a real mess on your hands.

If uncomfortable with this then relieve the pressure first. That's the safest bet.

On GPs, as an extra precaution, it can't hurt to disconnect the battery.

Hi Doug

So the relay removal etc is not necessary to get the filter off?

And sorry, what do you mean by GP?

Thanks again Doug

 

GP = "General Principle"

Removing the relay is the first step in one method of relieving fuel pressure from the system prior to removing the filter. It's the recommended in the factory service manual and is common practice.

The method I use and described does not relieve the fuel pressure prior to opening the system. I'm comfortable with it; others might not be.

Either way have some towels or rags under/near the filter to mop up the inevitable spill of gasoline.

AHH GP! hahah

I was also thinking of putting in some pre-filter filters. Is this worth doing? And if so any particular type you would recommend?

Thanks again Doug

 

Given that tank crud seems to be so common I think pre-filters are a good idea to protect the fuel pump.

NAPA 3299 or WIX 33299. Same filter, different box

Ok. Whats the difference between the 33299 and the 33033? They look identical but guessing internals are different??

 

33033 has 3/8" nipples.

33299 has 1/2" nipples.

The fuel lines from the tanks to the changeover valve are 1/2" ID so you need the filter with 1/2" nipples

Was just looking at them both and figured that would be the case. They don't say they come with fuel clamps though. Which is a bit annoying.

Thank you again Doug. Once again super helpful!

 

033 comes with two small sections of hose and spring clamps.

The 299 comes with nothing else, as I recall. You can usually reuse the original Jaguar clamps. You might want to replace the hoses in the trunk while your're at it. They're probably all original.

Hmmm never thought of that. I am guessing i can get the tubing from Autozone or amazon? Is there a specific brand or thickness you would recommend? Its all new to me but very exciting!

Thanks again Doug

 

The 1/2" ID fuel hose is a bit unusual but I've never had a problem finding it at a NAPA store.

The rest of the hoses will be 5/16" or 3/8". Very common. Most stores stock Dayco or Gates, both are good.

If you install pre-filters it'll mean opening the lines from the tanks to the changeover valve. You'll need to plug this lines while installing the filters. I use pieces of 1/2" wooden dowel.

hmmm ok thanks Doug.

I found this one. Decent?
