Don’t adjust your TV sets folks, if you have been paying attention on this channel over the last couple of months you know we very recently replaced the mechanical fuel pump on our Pontiac 350 in the 1968 Pontiac Project. Not to be out done, now the 455 Pontiac under the hood of my 1970 Pontiac LeMans is demanding one too! To make this even MORE annoying, this will be the 4th fuel pump on this car in the 10,000 or so miles since the car was put together!
When this car left me stranded just a couple days ago, I was almost certain it was an electrical issue. We’ve had intermittent ignition issues for the last several years and that seemed like the most likely culprit. Surely, this couldn’t be ANOTHER fuel pump. The one on it wasn’t but a few thousand miles old! Well, time to stop screwing around with factory replacement units and I’m stepping up to a Holley Mechanical fuel pump, vastly more expensive and HOPEFULLY more than capable of keeping up with the demand and abuse!
Here we go, Pontiac V8 Fuel Pump replacement time! For those curious, yes this is the same exact parts and process for essentially ALL Pontiac V8s, the 350 Pontiac, 400 Pontiac, 455 Pontiac, even the older 389 Pontiac, they all share this exact same pump.
Thanks to my friends at Jegs for actually stocking this part so I could get it in my hands and get my hot rod back on the road!

I would consider how much ðamage that ethanol gas is doing to those chinese fuel pump diaphrams.
I run ethanol free gas in my 72 LeMans and have had no problems. The ethanol could be eating up the diaphragm. Ethanol disroyed the carb on my old generator when I didn't have ethanol free to put in it.
Just replaced a fuel pump on a 79 Trans Am yesterday. What's with these dang pumps going out so often?
So what fuel pump did you install -I have two Pontiac Firebirds, both of them have fuel pump issues. Replaced both numerous times. Both run four hundred engines, ?
Hey did you ever verify if the sock was clogged?
Love your channel…Junkyard Kevin sent me!
Cut the oil filter open and look for metal.
What kind of oil and filter do you use?
A little gasket tack would hold you gasket in place
Put a small dot on the balancer so next time it be easy to do.
The new mechanicals are junk. I went through 6 in 3 weeks, got a Carter and had to run a regulator. new tank, New filters, New Lines, New sending unit/siphon. Our Local parts stores will tell you not to expect it to last. About 1 in 10 are good.
= SINCE quite a few FUEL PUMPS went BAD
&
Since the Part-Number is on "SPECIAL-ORDER" only – Status
I'ma' gonna' GUESS that the Manufacturer had a "BAD" Run of Pumps
&
delivered several of them to KENTUCKY !!!
