I notice a lot of Holly Red fuel pumps being used on the IDI's.
Question #1: Anybody know what press & Vol the mechanical 7.3 pump puts out? Or is needed to supply the IP? I seem to recall that it was rated @ 9-11 psi, but can't find it now. (from a past dream of mine...??) I recall that to test it, it needed to draw about 12 in Hg (vacumn) on the suction side.
Q#2: If an electric pump of hi vol/ pressure is installed, will this still work, or will a restrictor have to be installed. Will the IP still be able to handle the excess & just return it to the tank?
Reason I ask is that I have a too small electric pump currently in place & need a bigger one. I left my mechanical pump in place, disconnected it & looped a hose round from the inlet to the outlet to keep it sealed & trash out.
I have access (nearly free) to a Holly # 12-706-1 pump, but looking on the E-net at Performance Center.com they say:
<The high volume output of this pump makes it the natural choice for racers who will settle for nothing but the best. This pump features a gerotor pump design which is extremely efficient and quiet. Fuel pressure is pre-set at 15 PSI and both a pressure regulator and 3/8in return line to the fuel tank are required. This is a racing fuel pump and is not designed for continuous use.>
This same site above says about the Holly Red: <This externally mounted fuel pump is designed to work with stock or mildly modified engines. Pressure is pre-set to 7 PSI and a regulator is not required. This pump features a simple, yet rugged rotor and vane design.
Anyway, someone got some thoughts? I gotta do something different soon.......& I'm a cheap tightwad!!! :Sly
I run WVO, WMO, buttermilk, Gatoraid, bulls@*t, diet cola, & even diesel when I have my siphon hose with me after sundown....
Thanks
