REBUILT1966 HIPO 4201-S FUEL PUMP

Fred,

Do you know how many months out the fuel pump date can lag behind the vehicle build date? Build date on my Kar is May 20, 1966. Too late for this pump?

Much thanks,

Geoff

When looking for parts on the engine, don't we look at the date of the block and consider when the engine was likely assembled with it's components rather than the date on the door tag? I believe there has been some prior discussions around this. Charles has also commented that the date on the door tag was a projected date and could be off plus or minus 2 weeks. The door tag date on my car is July, but my engine has a Feb date. It is the original VIN stamped block to the car. I would suspect that the engine was assembled a short period after the block date so I've understood looking for dates on engine related parts around the block, rather than the door tag. I would also like to get Charles take as well.

21.04 - made a number of good points IMHO. Yes the projected build date on the door tag could be off by as much as three weeks in some cases in either direction. Also agree that we might want to compare the dates found on engine components to the engine assembly date, since the parts on an engine would not have been dated after that date (providing some lead time) instead of the cars build date.

Looking at my collection (limited as it is) the spread between the casting date and the assembly date on blocks seems to have been typically a week to three-four weeks during the 65-66 period.

My observations are pretty much in line with Jeff's. The only thing I would interject would be that K code engines typically could lag a little further behind in casting dates than normal C or A code engines.

Congrats on the sale of the fuel pump Fred! Although, I was amazed at what it went for, you do a superb job at these. It's obvious that others highly value the work done on them.

I think the modern internals that are compatible with today's fuels are a huge plus for those of us that want the correct part and also want it to work.
