Installation Instructions:

1. Make sure the ignition switch is off. Disconnect the battery cables at the battery.
2. Disconnect the ECU wiring harness connector.
3. Remove the water sensing module.
4. Remove fasteners holding ECU in place and lift ECU upward off studs. Disconnect MAP sensor hose at the manifold and remove the ECU.
5. Remove rubber mounts from top of manifold cover, set aside for later use.
6. Note the location of ground wires for reference during installation.
7. Remove the two bolts on the vapor separator going into manifold cover. Note location of any spacers for use later.
8. Remove any brackets or screws attached to bottom tabs of manifold cover. Trim relays may be attached directly to lower cowl pan. FIG 1.
9. Remove (12) manifold cover screws and carefully remove manifold cover so as not to dislodge the plenum box.
10. Inspect rubber gasket on plenum box, replace if necessary.
11. Remove SVS cover assembly and remove slide. Position SVS base on plenum box and secure with (12) 1/4-20 x 4 socket head cap screws. Torque screws to 120-inch pounds, working from the center outward.
12. Install slide into recess of base, be sure to correctly insert brass bushing of slide assembly into elongated slot in linkage. Secure cover with (4) #10 socket head cap screws and lock washers using loctite, torque to 25-inch pounds. Check for smooth operation of slide at this point.
13. Refer to FIG 2: Pull throttle actuator arm out of plastic clip A in throttle advance cam. Remove locking nut B and remove throttle advance cam. Set aside for later use.
14. Refer to FIG 3: Liberally apply grease to throttle pivot shaft C. Install provided spring D to screw on base linkage E, and screw on throttle cam linkage assembly F. Stretch linkage assembly onto throttle pivot shaft C aligning slot over bushing, FIG 4: G. Secure with lock nut removed earlier. Tighten lock nut to make full contact then back off 1/4 turn.
15. Refer to FIG 2: Locate original throttle advance cam previously removed. Remove plastic swivel A by pushing a 5/16 socket over the back of the swivel. Push plastic swivel into the new SVS advance cam, FIG 4: H. Install steel throttle linkage into plastic swivel H.
16. Reattach vapor separator using existing bolts and spacers.
17. Install rubber mounts to ECU bracket.
18. Mount ECU on bracket, attach ground wire. Connect vacuum line from MAP sensor to manifold. Connect ECU harness and secure with tie wrap. NOTE: It may be necessary to space water separating filter out with spacing washers.
19. Reinstall water sensing module to ECU.
20. Refer to FIG 5: The small bracket on the upper port side of the SVS is a provision for the final fuel filter on older model EFI units. If so equipped, it may be necessary to route longer fuel lines between the final fuel filter and the vapor separator. Position these lines to avoid any kinks. On newer model EFIs with internal final fuel filter, this bracket is not needed and may be removed.
21. Reinstall battery cable.

Linkage Adjustment:

The following linkage adjustments are to ensure that the original butterflies operate as originally designed, opening and closing fully, and that the SVS opens fully, at wide-open throttle and returns fully closed. These movements should operate smoothly without binding or having any interference.

1. Refer to FIG 4: Back off stop screws I and J so as not to interfere with travel of linkage assembly. Align marks on roller K with mark on throttle advance cam. Check for .005-.010 inch clearance between roller and cam. If necessary, adjust by loosening cam follower screw and moving roller to position, then tighten screw.
2. With throttle in idle position, adjust screw J to achieve .010 inch clearance with throttle advance cam. Tighten locking nut to prevent movement.
3.

Have an assistant operate throttle to wide-open position. IMPORTANT: Original butterflies MUST be wide open, if necessary, to adjust wide-open throttle position. Refer to FIG 6: Loosen lock nut and adjust screw L, tighten lock nut. Operate throttle several times to ensure wide-open throttle.
4. Refer to FIG 4: With throttle in wide-open position, adjust stop screw I to achieve wide-open throttle of SVS. Operate throttle several times to ensure wide-open throttle. Tighten locking nut on screw I to prevent movement.
