Zmanco Posted October 19, 2009 Share Posted October 19, 2009 For those of you with early Zs (70-73) and upgraded engines, what are you using for a fuel filter? I've finished my turbo upgrade and obviously my max fuel flow is significantly more than before. At the moment I only have a small filter between the tank and the pump. I'm guessing that the early stock filter might be too much of a restriction at max flow. FYI, based on what others have dyno'd with a similar setup, I'm guessing power is around 275 whp right now. I'm hesitant to just experiment in that I'm worried about leaning out under boost and causing damage. FYI, I'm a little space limited in the front passenger corner of the engine bay where the hardline from the fuel pump comes out due to several relays for headlights (mounted on the fenderwall a long time ago before I ever thought I'd go turbo) as well as the intercooler piping. So smaller is better as long as it doesn't restrict flow. How small of a filter can be used and still provide good protection without too much restriction of flow? Fuel lines are 5/16". Anyone with part numbers? Quote Link to comment Share on other sites More sharing options...
junglist Posted October 19, 2009 Share Posted October 19, 2009 Are you using push on rubber fuel lines with clamps or -AN lines & fittings? Quote Link to comment Share on other sites More sharing options...

Zmanco Posted October 19, 2009 Author Share Posted October 19, 2009 Are you using push on rubber fuel lines with clamps or -AN lines & fittings? Just push on rubber. I am looking for something more on the "affordable side", preferably something I can find at the local parts store. I was thinking of using the filter that's on my Volvo turbo (that engine is rated ~240 crank HP) and because I know its part number. But it's really big (bigger than a large soup can!), so was hoping someone found something smaller. Peterson 600.That looks like it's only for -AN, and I'm sure is a sweet part, but probably also more than I wanted to spend for this.

ktm Posted October 19, 2009 Share Posted October 19, 2009 I am personally using a Russell 40 micron SS mesh screen between the tank and the pump and an Aeromotive 12321 (http://www.aeromotiveinc.com/products.php?prod=261) 10 micron after the pump. You can't really go with a "small" filter that is filtering out particles down to 10 microns. Surface area is the key to maximizing flow while filtering out the smallest of particles (10 micron).

Zmanco Posted October 19, 2009 Author Share Posted October 19, 2009 e30 BMW. Good size, cheap, metal case. From the Checker site showing where else it's used: http://shop.oreillyauto.com/ProductGuide.aspx?mfrcode=FRA&mfrpartnumber=G3829 Looks like it's also on 91-93 M5s as well as several big V8 Mercedes so I doubt flow will be an issue. Hopefully it's smaller than the Volvo... Thanks Drax, that's the kind of suggestion I was looking for. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted October 20, 2009 Share Posted October 20, 2009 It's not tiny. Somewhat smaller than a can of chunky soup, but not as small as chicken noodle. Quote Link to comment Share on other sites More sharing options...
Tony D Posted October 21, 2009 Share Posted October 21, 2009 I learned years ago to carry an extra pair of socks in the car... Sometimes you get this feeling at a remote desert filling station about how often their premium tank is actually turned over... So you whip out the old nozzle, slip a double sock on it, and GO FOR IT! Live life on the edge... Later, as you realize the red stains on the socks were not from the last time you walked barefoot from the tent to the Z in a stupor...as the car vapor locks and comes to a stop on the hills outside ABQ NM... That maybe, just maybe you got a bad tank of gas. And even going in with protection didn't stop the gas crabs from making your day terrible. Then you get to lie on your back changing the large filter you just installed before the trip, thinking it was big enough to 'last a lifetime' but in reality it only took one dirty deed in the remote desert wilds of Arizona to make your nozzles do nothing but drip drip drip with a reddish tinge and a full heart of regret for what you did the night before... 1 Quote Link to comment Share on other sites More sharing options...
Drax240z Posted October 21, 2009 Share Posted October 21, 2009 Hold on Tony.... what were you using the socks for? Or maybe a better question, did you use the socks again after filtering the tainted gas? Quote Link to comment Share on other sites More sharing options...

josh817 Posted October 28, 2009 Share Posted October 28, 2009 Peterson 600. Sounds like some sort of rendition of a porn star. On our UIL competition tests at school, if we didn't know the answer to a question we would put Peter North. If you don't know who he is, do a google, don't click on anything, just read the little summaries.... I have this installed. Honestly, mine didn't come with a sticker on it because it came with my carbs. I didn't know Fram made fuel filters, don't know if they're any good, but I use it up front and then those small cheap plastic ones in the back before the pump.

Zmanco Posted October 29, 2009 Author Share Posted October 29, 2009 I went with the BMW E30 filter Fram #3829 $32 at Checker. Body is 3" x 4.25". Fits nicely. Quote Link to comment Share on other sites More sharing options...
cygnusx1 Posted October 29, 2009 Share Posted October 29, 2009 I use this one before the fuel rail. 40 microns and supposed to flow enough fuel for 1000hp....although I find that hard to believe since it is so small. It certainly supports 300hp in my car, I can confirm. I should probably shoot for 5-10 microns though? No? http://www.summitracing.com/parts/EDL-8130/ I used hard line to AN compression fittings to plump it into the stock hard lines. Quote Link to comment Share on other sites More sharing options...

Evan Purple240zt Posted October 29, 2009 Share Posted October 29, 2009 I also use that fram filter, mine is about 10 years old. The element is a few years old. Maybe time for a fresh one. Evan Quote Link to comment Share on other sites More sharing options...

No? http://www.summitracing.com/parts/EDL-8130/ I used hard line to AN compression fittings to plump it into the stock hard lines. I was running the Russell version of the same filter. It is simply a stainless steel mesh disk. After I rebuilt my engine, I installed the filter I mentioned earlier that filters down to 10 microns. I am still running the Russell before the pump and the Aeromotive immediately after it. I strongly recommend running a 10 micron after the pump. You do not want to clog a fuel injector and then go very lean on a cylinder under boost. Quote Link to comment Share on other sites More sharing options...
