I need to slap a new fuel pump on my 72 small block. It’s the 3 hose pump. Any suggestions on best replacement pumps? I’ve been reading in the C2 forums that certain replacement pumps (for big blocks) are junk, make noise and just don’t perform well. Any suggestions on which I should be looking for?
There have been numerous threads on here in just the last couple years on this very topic.
Seems a lot of people have had a lot of issues with replacement pumps.
Im thinking the local auto parts store wouldn't be my go to.
many mention the RobMC pump. And anything Jebby recommended would also sound good.
If you have an OEM pump, there is a guy in California that rebuilds them. I can hunt down his name, but it does take a good bit of time for him to compel the rebuild process.
I just put in a Delphi MF0026 in my small block. It looks exactly like the original and I am happy with it. I only have one suggestion and you probably already know it. Make sure you have a container big enough to hold all the gas in your tank. When you take the supply line off, the tank will drain every drop of gas. My tank was pretty empty, but if yours is not it is tough to find a place to put 10-15 gallons of gas. I used a hose from the supply line to a 5 gallon gas can which was enough in my case.
This fuel pump task should not drain a tank.
I put 2 X 10 boards under my steel ramps.
Plug the end of the line with something.
Lost maybe a drop or two of gas.
You must get the front end up in the air.
Less than half a tank is ideal, but sometimes you don't have an option.

That would be Fred Ballard. He did my original L71 pump rebuild. Nice job and works great. Uses innerds that stand up to ethanol. Has the correct crimping machine too. His contact is:

I did clamp the supply line shut while I took the pump off of the car, but I also decided to replace the short supply lines. They were in pretty bad condition. Some guys put a bolt into the supply line and clamp it with a hose clamp. With the limited amount of space to work, I did not feel that I could change the line quickly enough to keep gas from coming out of the supply line. I decided that it was safer to let the tank drain.

I have seen people use "C" clamps, Vise-Grips and even large forceps from a medical supply store.
Not a big fan of squeezing the **** out of any rubber lines, (especially brake hoses)
They say there is no harm done on clamped fuel lines / vacuum lines.
But no one would ever see any rupture internally, so I plug lines, not cripple.
To each their own.
I've done this job a couple of times now. With the front of the car on jackstands and the rear of the car on the ground. Fuel loss is minimal. And yes it's always a good idea to change out those S hoses.
If you’re gonna crimp it closed do it at the tank end.
You mean the hose that is hard to get at, can't see it and awful thing to replace?
No thanks.
For those wanting to temporarily plug a rubber line:
Looking around in my toolbox I came across a punch. I believe they are called drift punches. Used in metal, pin-point, commonly used to start a drill bit.
They have a taper that fits and plugs about any rubber hose, very tightly, while you change-out a fuel line or pump.

I replaced my fuel pump with one I got from NAPA part #B-0172-P about 8 years ago. As I recall it was made in South Korea. Works great. My engine is a 350/300 in the 69 coupe in my avatar.
