Yes, I did have feed problems when I initally installed toe Holley Pump. I now
mount them inder the boot floor either side . I consider them to be well
protected by the frame crossmember and the lines come UP thru the floor and run
internally. Never been a problem since the install. The twin setup is pure
redundancy and almost certainly not necessary. Steve

Subject: [Fot] Holley Red Top fuel pump question
List,
Holley recommends that their fuel pump be installed so that the pump is lower
than the fuel level. Has anyone had a problem with the pump installed
differently?
My dilemma is that my fuel cell sits low (in a cut out with brackets) in the
boot of my Spitfire and the previous owner had installed the old Holley pump
lower than the fuel level but in what I felt like was a dangerous place as it
was exposed under the car and the fuel lines were also routed where they could
have gotten easily damaged (basically very close to the wheel well). I?m moving
the fuel pump and the lines to be inside the boot but it is not possible to
make the pump sit entirely below the fuel level since the bottom of the fuel
cell sits below the floor of the boot. The chosen location makes the pump sit
about 1/3 of the way from the fuel cell bottom.
I know Holley wants to take advantage of the siphoning effect (apparently
because they push fuel better than they pull fuel) but does that matter as long
as the fuel pressure is maintained at the proper level for my carbs? I figure
if I run with the fuel cell full (8 gal) the fuel level will be above the pump
the majority of the time. I?ve been burning about 3-4 gallons per (20 min.)
race.
Has anyone had issues with the Holley fuel pumps not being installed exactly
like Holley says? I?ve seen some other Spitfire racers with the Holley fuel
pump NOT below the fuel level so I?m hoping it works for me to do the same. I?m
thinking about one of the two locations shown in the pics. Right in front of
the fuel cell is my preferred location at this point as the other location to
the side of the fuel cell would be more vulnerable in a crash situation.
Thanks
