  • About my Cars
    I owned a Datsun Dark Blue 1971 240z from 1977-1982. Bought it for $2400 with 42,000 miles. Never used in winters and eventually sold it June, 1982 after our1st child was born (for the same price I bought it for - $2450 with ~63,000 miles. My 240z interest was renewed as I purchased my 2nd one (Orange) in Oct. of 2006 and my 3rd one (Green) in July of 2007. Both recent 240z's are 1973's, Orange 11/72 and Green 9/72. Moved from MN to NY in '08, sold the Orange 240z and kept Green 1973 240z, HLS30-124668. In 12/2010, purchased my 4th Z, a 370z Sports Package in Black Cherry w/6spd Manual.

  1. Sweet Wheee (Mark), thanks for the comment!! Would love to see pics of them when you can send them..... Essentially we have 40yrs of technology difference between the 370z and 240z.... but being gated they both put smiles on our faces!!!!! Take care... Mark
  2. Many thanks for sharing! Great info to always check these fuel bowl/nozzle hoses when I pull the Airfilter backer plate. I am very much like you as I often fiddle to assure the engine components are always working to spec so I can head off a problem before it fails completely. Started to have bucking/jerking when accelerating or going up hills, a loss of power problem. This occurred after installing ZTherapy SU's and tuned them with Colortune also. Thought it was my SU's and needed to tune/tweak them. Finally after it finally stalled completely and would fire sporadically but not run I figured electrical problem misfiring? Got it back to my garage I thought to check the rear fuel bowl for the heck of it since it was easy... and sure enough it was almost completely empty. Front fuel bowl was topped off pretty close to normal. Replaced the mechanical pump and then added an electric pump for insurance.. my 4BBL Holley was more forgiving when the mechanical pump was marginal ... my SUs were not! Thanks again for sharing....
  3. Nothing but Gated Garaged Vehicles !!! The thrill of driving stick always puts a huge grin on my face .... 1973 240z (Viper Dark Green Pearl), 2005 Ferrari F430 (Rubino Micalizzato-Burgundy Pearl), 2002 Ferrari F360 (Rossa Corsa-Red), 1991 Toyota MR2 Turbo (Red), 2010 370z (Black Cherry).
  4. Ah..... thanks. My initial thought the Right Lever was for the Air Box flap (close it for cold startup)..... but never thought it was for the gas pedal. Thanks!
  5. My curiosity is getting the best of me so I decided to ask the experts here.... maybe I am brain dead and missed something, I have searched on this site and cannot find any explanation. Q1) What is the Right Lever for on this 240z choke assembly? Q2) Is it specific to a Year? Many thanks...
  6. Polishing up the new end makes sense, only the metal and stay away from the plastic ball. Be careful to not take off the plating... Then re-assembling the ball end with the threads should be easy. Just be sure as previously stated to note the Center-to-Center ball distance from your original rod. Once cleaned the ball can be easily screwed onto your good shaft, just clean your threads on the shaft before attaching. The nut on your original rod is used to lock the threaded ball end at the correct length and orientation. There should not be any significant force torquing the threaded ball end on. Good luck...
  7. Patcon... here's what I found in the 1971 240z FSM ..... Static pressure tested at Carburetor Input running engine at various speed : 3.4psi - 4.3psi Capacity Test at 1000rpm : 1600cc/min ==> 0.423gal/min ==> 25.4gal/hr .. or 3.71pts/min ==> 0.464gal/min ==> 27.8gal/hr ... I guess .... 30gph is sufficient for our SU's.... based on the FSM. 1971 FSM 240z Fuel Pump Test.pdf
  8. True...... 👍👍👍👍👍👍👍👍👍 .... but I would hope the higher flowrate keeps the fuel bowls in short bursts full when accelerating.
  9. My mechanic says that although PSI is important to maintain the proper fuel system pressure/response, the FlowRate is the key parameter in filling the bowls. 30gph is the flow rate rate for both the Airtex 8016S (2.5-4.5psi) and Airtex 8012S (5-9psi) pumps which works nicely for SU's and Weber DGVs . Airtexs are very quite based on feedback here and external reviews. For your triple Mikuni's .. try to find out what FlowRate is needed and use a lower psi pump that fulfills that. From above... the Nismo 17010-A7601 puts out 1.3L/min ==> 0.3434gal/min or 20.6gph. This seems way to low of a flowrate.... you need at least 30gph or higher... The Airtex 8012 will be better, but not sure it satisfies the triple Mikuni's needs..
  10. Thanks MMaras for input.... I'll go with the 2.5psi-4.5psi Airtex 8016S ... it still has the 30gph flow rate ... so it makes sense!
  11. The Airtex 8012S is rated 5-9psi at 30gph.... shouldn't we use Airtex 8016S which is rated 2.5psi - 4.5psi at 30gph ? Just curious ? I am looking to add one to supplement my Mechanical pump as backup... Many thanks.....
