HOSE ASSEMBLY
10. Select appropriate Russell hose ends for each section
and temporarily screw them onto their respective
adapter fittings to determine hose length. Use supplied
Russell hose clamp with cosmetic socket cover to
attach hose to barbed hard line coming off fuel tank.
NOTE: Route hoses away from exhaust system and
hazards such as driveshaft, exposed electrical
connections (641580/641590 kit), and suspension
pinch points. Do not expose hose to road hazards by
routing below framerails. Also, some motorsports
sanctioning bodies have regulations on fuel hose
routing. Consult appropriate rulebook if vehicle will be
used in competition.
11. Mark supplied Russell hose at point to cut and wrap
hose over cut point with masking or strapping tape to
minimize fraying. Allow enough slack in length for hose
expansion, movement of components, and smooth
bends. Hold hose in vise and cut with a pneumatic
cutoff wheel, heavy-duty shears, or hacksaw. Cut hose
as straight and square as possible
(See Fig. 4)
.
Remove tape after cutting hose.
12. Unscrew red socket from hose end and hold in vise.
Push hose into socket, turning counter-clockwise, until
hose is seated on step in socket
(See Fig. 5)
. Make a
mark on hose at end of socket.
13. Apply assembly lube (motor oil, etc.) to threads on hose
end and in socket. Insert hose end nipple into
socket/hose and start threads by hand (clockwise). Turn
hose end with wrench until there is less than 1/16”
between nipple hex and socket
(See Fig. 6)
. Make
sure socket did not move on hose by observing mark
made in Step 16.
14. Repeat Steps 15, 16, & 17 for other end of hose.
15. Flush hose with solvent or hot soapy water and blow out
with compressed air or let air dry
(See Fig. 7)
. Install
hose. Use supplied cushion clamps and/or cable ties to
secure hose
(See Fig. 8)
.
FUEL PUMP RELAY
16. Mount Edelbrock fuel pump relay at suitable location
under hood (e.g. radiator support, inner fender, firewall)
away from extreme heat
(See Fig. 9)
.
17. Run one large (12 gauge) red relay wire back to red lead
wire on fuel pump. Wire can be routed underneath
along with other wires, hardlines, etc., or through
interior. A 10A inline fuse is recommended on this
circuit (not supplied). NOTE: Route wires so that any
possible cutting, chafing, snagging, pinching, or burning
from suspension, driveline, or exhaust components will
be avoided. Cover wires with supplied Russell Wrap-It
protective sleeve, and use supplied cable ties to secure
wires.
