Non-functional new fuel pump

[Grandpa Stude]

The old fuel pump on my 51 pickup finally gave up the ghost, so I installed the new spare I had.It didn't pump either. I took both to the bench and compared them. The levers exited the pump body at different angles. I knocked out the pivot/retaining pins and matched the two levers. The shape was good, but the pivot hole was off about 1/16". I installed the old lever into the new pump, works just fine. Never throw anything away.

Yep!!!! or in my case after trying 3 different new fuel pumps
(2 from a stude vendor and 1 from a auto parts store) and none
of them working on my 64 Datona...as you said all the levers
were at slightly different angles. I then had the 43 year old
one rebuilt and it worked like a charm!

I'll rebuild an old Carter before I buy another one of those new Airtex ones. They're junk.

Wait a minute! I think some of you are talking 6 Cyl. and some V-8!! Which is which? I would think Grandpa's '51 if original, was a 6, but the other 2 probably not! [?]

I have never heard of a "bigger piece-O-junk" new Airtex copy of the piece-O-junk AC (GM) Stude. V-8 fuel pump replacement for the real deal OEM Studebaker/Carter not functioning, just leaking oil all over the place!

Are we now having "no pump" problems with them too!!!!!!!![?] Sheesh![V]
Please clarify! [:0]

I was talking about Champion 6 pumps, Rich. We got a box of Airtex pumps for a 6, and I probably went through 4 or 5 in a year on the Orange truck. [}]

O.K., now you folks are scaring me. Yup, the '51 2R5 is a six and, near as I can tell an unrestored original. With, however, the occaisional bit of creative license perpetrated by previous "mechanics".The AC fuel pump I removed looked to be Johnson administration if not factory. I installed new floors and brakes this summer, now all I need is to finish adding some lights and turnsignals, since I'm sure nobody in northern Virginia knows what hand signals are...("Honest officer,he had his arm out the window and I thought he was waving me to pass!")

AC is factory for a six, I believe. V-8s got Carter pumps.

Northern Virginia? where you at? I'm in Falls Church.

I'm sure you remember Rich, from last year, when my 64 Daytona
V-8 was having fuel pump issues. The original, 43 years old, was
leaking fuel. So I tried 2 "new" ones from a Stude vendor, both of
which would not work, when placed on the car. The 3rd one was from
NAPA and again would not work.....When we placed all 3 together,
as "Grandpa Stude" said in his original post, that the levers angles
were not the same. So I had the old one rebuilt and never had another
problem. Since the thread started out kinda of generic, I replied
with my generic response with the issues I had. Was it "Apples to
Oranges"???? Yes but not intended. But you can look at it as both
6's and 8's have fuel pump reproduction problems, at least that is
how it appears to me.

Just for grins (since I'm about to install a fuel pump), how would one verify the operation of a pump prior to mounting it?

In my case, Clark, when we bench tested the 3 "new" ones to see if the
proper pressure was there, in all 3 cases, the bench testing was good.
But when they were put onto the Daytona and driven....it would stall
out and die....which is when we started to look at them along side of
the old one....each was different by just enought, from the 43 year and
its lever angle. That is when we bought the rebuild kit and sent the 3
back to the vendors. So my advice is look at the old one (if you still
have it) and the new one (side by side) and see if they are the same.

Thanks, Glen. I have my old pump (have not replaced it since it was working well when the engine came out); I just want to know how to bench test it.

I'm "brain dead" on that Clark....They were bench testing the "new"
ones, only to make sure there was enough pressure in the fuel pumps
to make them work properly, as that was a thought behind the failures.
There was! Maybe someone else can help us on the correct proceedure to
test. Since the correct pressure was seen, in each one, in theory they
should have worked. That is when we started to look to see if there were
any differences in design and that is when we saw the "arm" angles, being
different. Which started off this "whole thread".

I am guessing that you wouldn't have to test to see if the correct pressure
is there....your biggest concern, is whether the new and old match one, as
described.

I understand about the arm angle, Glen. But I'm not putting in a new pump I just want to make sure my old one sucks gas after 2 years in the bottom of a cardboard box, before I bolt it on!

Clark, I looked at 1 of last years posts....I called it a pressure
test....the term that was used was: "vacuum test"....still for the
life of me, I can't remember how they had set it up in the shop.
