[NoVa-Corvairs] Fuel Pumps

[Darrin Hartzler]

Great info...thanks for sharing this.

I have rebuilt a pump with an old Clark's kit...not that hard, but for 
only $10 more than this kit you can get a new Clark's pump.  Too bad it is 
not $30 instead of $50, I would do a few.

[NoVa-Corvairs] Fuel Pumps






Al Birks passed the following along to me. Looks interesting.

In the magazine Antique Automobile (AACA Magazine) I read that the Antique 
Auto Parts Cellar was offering fuel pump kits with the diaphragms made 
from Buna rubber. This material is supposed to be able to handle "Today's 
Gas". I asked if they offered Kits for Corvair fuel pumps and how much $. 
I gave him the pump number AC 4886.
 
Here is the interesting response I received. He really goes all out to 
answer the  question I submitted.  Some of it may be of interest to Hot 
Air Mail readers.

Dear Mr. Birks,
    Thank you for your kind inquiry.
    Kits for the two versions of Corvair pumps are available, but since 
the pump differs radically from the rest of the mechanical fuel pumps 
made, the contents of the kit differs as well.
    The list of kit parts in my advertising covers 99.5% of all pumps even 
made...but the Corvair steps outside those bounds...
    The Corvair kit consists of:
    -gasket from pump to engine - a rubber O ring
    -the pulsator diaphragm
    -the main diaphragm as an assembly of steel plates, two diaphragms, 
and a die cast plate (this is currently an industry standard diaphragm I 
stocked in back when I could-they went obsolete in 2002 in Canada, the 
last place making them. When stocks run out, I will be making them myself, 
as i do with almost all of the kit parts, and the die cast plate between 
the dipahragms will then be saved from the old pump)
    -the diaphragm spring
    -two check valves, made by me (custom machined aluminum alloy body- 
not the zinc die cast industry standard; die cut military spec viton valve 
plate-not the medium grade black rubber used as industry standard; conical 
check valve spring which allows it to compress into itself minimizing the 
restriction on flow)
    -two check valve gaskets (a part which is being omitted in most 
currently made pumps yet is necessary to be sure the check valve seals to 
the pump so that it is the only way for fuel to move!)
    -there would be very little point in making those parts advertising 
them, and supplying them all over the world if they would not perform 
their function. I have made more than 60,000 fuel pump kits over the last 
25 years. If I were doing something wrong chances are it would have caught 
up with me by now?
    In the Corvair pump successful rebuilding often relates to getting the 
die cast metal surfaces flat again so they can seal...especially the plate 
that is between the diaphragms.
    And you have to realize that there are two different pumps, and these 
pumps are operated by two different push rods....each comes in a long and 
a short version...mix short with short, no pumping. Mix short and long 
things work. Mix long and long and the extra travel in the system 
overstresses the diaphragm and failure occurs, either instantly or soon...
    The kits are $37.50 and $ 12.50 covers shipping and handling by UPS 
within the continental US.
    We take the usual credit cards and ask that you phone or fax us to 
order- we cover our phones Monday to Friday from 8am to 5pm at 
781=335-8860 and from 10am to 7pm at 781-335-1579. Our fax is always on, 
collecting junk and occasionally useful stuff at 781-335-1925.
    We also offer rebuilding services on these pumps at $ 85.00 for labor 
and kit parts, as well as new pumps at $ 95.00. Of course they are cheaper 
from the specialty houses- but i know where and when my stuff came from!
    Hope this helps,  Tom    Antique Auto Parts Cellar    and    Then & 
Now Automotive
