I am gathering up some stuff to put away for the potential trip home in oct/nov from MT to MS in the 63 cdv.

i thought a fuel pump may be a good piece to have nearby,  Are the newer ones like you can get at rock auto reliable and do they fit as they should or are original pumps around and a better bet/   Jason or Russ?   

Thanks,,

I have never had any issue with the original or new aftermarket or rebuilt original style, but have heard there have been issues with some of the newer or rebuilt ones. Russ reported he had seen where they had not staked the valves in place, causing them to come apart and stop pumping. I have found the best new aftermarket pump, which looks like the original style fuel pump is the Spectra Premium B1297MP fuel pump. For years I kept a stock of new ones but the supply run out. AutoZone lists them now for about $70 but when you go to check out they are out of stock. The other new fuel pump I have seen in the last few years has been the Airtex 6744 Fuel Pump. I have not experience with this fuel pump but believe it may be the one others have had issues with the valve not being staked.

For years there were new single uni-body pumps available at auto parts stores like the one seen on the right in picture below that did not come apart. I also had not issue with those. 
If you want good used from known running engines, I sell the original style like seen on the left for $40 and the unibody style like on the right for $20.  

 

I put a new Airtex pump on my 63, it worked well for 15k miles until the inlet valve fell out of the pump body. The valve was not staked in, just a press fit causing the failure. If you buy the Airtex pump, take the bottom cover off to see if the valve is just pressed in. If so, stake it with a punch so it won't fall out. 

ok, thanks for the information,,,helps me out making a decision

Spectra Premium SP1297MP Mechanical Fuel Pump for 85:86 USD.

Not sure if its the same B1297MP Jason suggest.

64 Power Servo vacuum leak

Posted by Kent Prows on June 27, 2020 at 4:02pm 0 Comments

I finally got around to fixing a leak in my heater core.  I decided to check to see if there were any other obvious issues while I had everything torn apart.  When I put a vacuum directly (bypassing the transducer) to the power servo it gets to about 10" and then slowly leaks back to zero.  The fan will not go to full and the mode door will not open completely.  I have read a couple of other posts that said they repaired the power servo leaks.  How?  Does anyone have one to sell?  I just…
