BrianG Posted March 5, 2005 Share Posted March 5, 2005 In my attempt to relocate the fuel pump on my V-11 Sport, I have been looking for a smaller fuel filter. There are many automotive "fuel filters" of appropriate size, but they are not designated as specifically "Fuel Injection" type. I wonder: Are non-F.I. fuel filters inappropriate for locating in the high-pressure side of the F.I. system? Would it be sufficient to place one of these non-F.I. filters right in front of the fuel pump and forget having one in the high-pressure side?

al_roethlisberger Posted March 6, 2005 Share Posted March 6, 2005 If you use the filter on the inlet side, you may starve the pump, as it is quite high volume. On the high-pressure side, you absolutely must use a filter designed for 3+ Bar of pressure, otherwise it will rupture. So, no you cannot use a filter not designed for this application. I think some folks found an Isuzu filter that supposedly fit, but think that info was posted on the "old forum" and may now be lost. In any case, it was about the same size, and the allure was simply that it was much less expensive. I think that if you could find a filter that met the flow(which I don't know) spec, and met the 3+ bar pressure spec, you may find one that would work, but I don't know of one off hand. You might run a search of the forum for "filter", but I'm not sure that this angle has been pursued before, or with much effort. al Link to comment Share on other sites More sharing options...

BrianG Posted March 6, 2005 Author Share Posted March 6, 2005 What about a tiny one like the one that is a part of the "in-tank" pump in the newer V-11's? Is there also a larger in-line one, downstream? Link to comment Share on other sites More sharing options...
al_roethlisberger Posted March 6, 2005 Share Posted March 6, 2005 Nope, just the one in the tank.... there are some closeup photos and info on that filter in my "2003 tank retrofit" thread, but know nothing of its specs, etc You could call a MG dealer and see how much this little gem costs, I'd be curious myself. al Link to comment Share on other sites More sharing options...

All BMW K-bikes and oilheads use the same filter(p/n 16 14 2 325 859). About $16 bucks from BMW. Several BMW riders place these outside the tank for ease of maintenance. I have heard of no problems.

dlaing Posted March 6, 2005 Share Posted March 6, 2005 Here is a photo of a Deutsch FF424, about the same size as an Isuzu Trooper filter: Goto http://ibmwr.org/r-tech/oilheads/ and look at the external fuel filter articles. And from here I found some more cross refs that should work with our bike http://www.users.waitrose.com/~paso/parts.htm) : BMW K100RS part number: 13 32 1 461 265 (8mm) or 16142325859, Purolator F20011, AC GF61, Fram G2, Motorcraft FG-2, Wix 33032, CarQuest E2036 (mid-80's Ford Ranger.

dlaing Posted March 6, 2005 Share Posted March 6, 2005 This is a little smaller than the Isuzu and Pathfinder filters, and probably about the same size as the Beemer filter. But hunt around and you may find something smaller Here are the specs on the Wix Part Number: 33032 UPC Number: 765809330320 Principal Application: ABG Construction Equipment, Ford Festiva (88-91), Various Early Model Import and Domestic (Universal 5/16 in.

Mike Stewart Posted March 7, 2005 Share Posted March 7, 2005 I am also looking for a smaller fuel filter for my 1100S project bike. I don't know why a bike would need a fuel filter larger than most automobiles The fuel filter change intervals on most Chvrolets is every 36,000 miles and on the Goose it is every 12,000 miles, go figure . And how much fuel flows through the filter to the eight cylinders in the Chevy verses the two cylinders on the Guzzi? Now my head really hurts.

Now my head really hurts. Mike 45398[/snapback] Just in case you were NOT joking, Mike. That filter passes 100's of times more fuel than the bike burns, as it is recirculated over and over............ through the return line, past the regulator and round and round.

I got this unit today fromthe local Canadian BMW dealer. An what with the current Canadian dollar being worth $0.80 US, it stands to reason that the thing only cost me $31.00 Link to comment Share on other sites More sharing options...
