427 Fuel pump change


I decided to work on this Pontiac instead of dreaming of other cars.

The diaphragm had blown out of the fuel pump in September.

This aftermarket filter needed to go as well.

Lots of imposters out there.

The right one was on the car and requires rubber hoses for all connections. 

2nd from the right, is a "Car parts supplier" $20 filter.

Next is an "Authentic" replacement filter from "Parts Place" on-line store.

The one on the left is the Jewel in the crown. October 1968 dated NOS part of Ebay.

The $20 filter(right), only had an opening of about 3/16 or even smaller.

I decided to play with it and drill the hole bigger. I basically ruined it.

It should have been the size of the other two.

The NOS will be used on the 2+2 project.

The lines are from In-line Tube from Michigan.

Two of the original lines are good with one cut.

I guess it could have been flared out with a new fitting.

I'll be keeping them for future use.

 

Now the scary part for me.

The fuel pump push rod will fall down and the small block trick bolt does not exist on this motor.

Consulted several experts and only Mark replied biggrin

By removing the square-headed plug, I could remove the pump pushrod.

Mark says "Just put some heavy grease on the shaft and that should hold it !

Of course it worked, Thanks Mark !

Now the fuel pump itself was a bit of a challenge.

I ordered two Carter pumps from Rock Auto. One for the 2+2 project.

When I took one to the engine builder, he tested it right away.

You can put all your weight on the lever and nothing moves.

"That will break something" he said.

The other Carter moves fine and is already on that motor.

I dug out a box that I have had for years.

Full of carb parts and this "Made in Canada" fuel pump. (Middle)

The arm was identical to the others so I am using it.

The car fired right and the only leak is from the old rubber fuel line at the pump.

022a.jpg

I'll change that and the heater hoses next.

Oh darn, too late now to drive to Sarnia to look at that Impala.

Another load of 12-hour shifts coming up.

That car should be sold by the time I get another day off biggrin

Using a hacksaw blade between the pushrod and arm works well to hold the pushrod up while installing the fuel pump.
I've had to improvise in a motel parking lot with a plastic knife from the breakfast buffet, it also worked well.
