Which Fuel Filter

MAS956 · 06:43 PM

Okay guys,

I have done a lot to my car in the 5 yrs I've owned it, but today is the first time I've attempted to change the fuel flter and I'm a little perplexed.

The Mahle filter on the left is the replacement for the Bosch on the right that I just took out of the car. Is the Mahle (KL22) the correct replacement for my '82 SC? It is considerably larger in diameter than the Bosch it replaces and it has a male fitting on top and female on bottom whereas the Bosch has both male ends...

Do the brass (?) fittings unscrew from the filter - they seem to be in there pretty tight although I haven't gone to the vice yet....

Thanks,

Hi Mark,

Don't know about if the Mahle filter is the correct substitute but the brass fitting will unscrew out of the Bosch filter. You will need two wrenches a a bit of grunt. Be sure to preserve the copper sealing washers as well. I needed to move the ones on mune around to get the filter to fit in my '73 (http://members.rennlist.com/harryd/1973fuelfilter.htm).

Will the new filter fit where the old one went or will you need to make a bracket?

I think the ew filter will probably fit in the spot, but a further concern is that the original ff had a 19 and a 17 mm fitting and both on the mahle are 19.... One on the orginal may be a reducer....

Thanks,

Go to a good hose shop and have them find the fitting you need. The one I uses services many local industrial accounts and a great assortment of the correct fittings. Failing that, they can take your fittings and weld them together to make a fitting.

Have fun.

Where did you get the filter? I'm getting ready to order one from the host & hope I don't have to deal with fabricating brackets & fittings that don't match.

Replacement part is from our host.

The bracket that the old one sat in seems ready to accommodate a larger fuel filter, but I'd like to know the story before I start to kludge together a solution....

Thanks,

My 86 has a Fram.

I bought the Mahle and was gonna replace it. I got the top bolts off, however the bottom bots to the Fram are frozen on. I tried two wrenches and put so much tork on it that I was afraid of bending or breaking the fuel lines.

No budge... tried Liquid Wrench...no budge.

Fram is still there. Mahle is sitting in the trunk

Hey guys, anyone BTDT with this fuel filter fitting prob?

Thanks!

The new one is the wrong filter. For some reason almost all supply houses list the wrong fuel filters for SCs.
I went around and around on this issue last year. Can you read the number on the old filter? I'm betting it's 0 450 905 016.....

Call pelican and ask them if they can supply that exact filter. Don't tell them what year or model, just that number.
If you can't get it from pelican, I'll tell you where you can.

Sam,

I'm almost certain that the p/n you suggest is that of the old filter - thanks for helping me out with this one - I was about to force the new one to work but that didn't feel right...

Now how do I diplomatically tell our host that they screwed up? I'm sure Wayne'll throw an old copy of his engine rebuild book in with that replacement filter!

Looking at our parts info; the correct filter is 928 110 147 05
( or 928 110 253 06: superceeded from 04 and 05 we just got an 06, well, that's what it said on the box, in the box it was an 04 "made in the Czech Republic") which according to the buyers guide will also fit the 928/944/964/993; that is the KL22 you have. If the bracket is correct size for the larger filter then maybe something has been changed on the car or it's using parts from the up-to-80 model year.

sammyg2 · 06-14-2003, 11:13 AM

It's not pelican's fault, they sent me the wrong filter last year too. The parts catalogs are screwed up so they sent what the book said was supposed to fit.
They will take good care of you, just make sure they understand the situation and the filter you need.
Did you say that on the old filter you have two different sided threads?
On the filter that came with my car the threads in both ends were the same, 13mm IIRC. The filter that everyone said was supposed to fit had 13mm threads on one end and 12mm on the other.

When I did my update, I noticed on the -016 filter, the female threads on both ends of the filter body are the same size but the flares to connect to the rest of the world are two different sizes.

Maybe that clears this up a bit.

My 80SC has a Bosch 0 450 905 016

Just to ad I feel it's cheap insurance to change the filter more often than what the owners manual calls for, Mine get's changed at least ever 10K mile's or every other oil change. I don't want no stinking dirt in my fuel system.

sammyg2 · 06-14-2003, 04:45 PM

Looks like we have consensus, the 016 filter is the correct one for our SCs but the parts catalogs disagree and try and sell us a 928 filter that does not fit without serious mickey mouse engineering.

MAS956 · 06-14-2003, 08:14 PM

...and it's the 016 that was in there, so now I can replace it w/o feeling as if I were compounding the po's mistake.

Thanks, guys!
