Fuel Lines for D/P Holleys
Head Specialists manufacture a race quality fuel
line set up for double pumper Holleys. Machined
from alloy bar with big 5/8 ID size. Quality alloy
screw in fittings, has provision for fuel bypass
and fuel pressure gauge with all red and blue anodized
fittings suitable for alcohol or petrol.
We have found that with the big capacity of fuel
this line holds it stabilized fuel pressure better,
giving a more tuneable fuel curve and more even
fuel flow to the needle and seats allowing consistent
fuel bowl levels, resulting in more power.
Head Specialist's signature series valve covers
for SB Chev's. Sturdy cast alloy available polished
or matt, with dual breathers on one side or no
breathers at all. These come with our logo engraved
into them and are extra thick around bolt holes
to eliminate messy and dangerous leaks. e-mail or
