Title: 1948 Plymouth Fuel Pump
Post by: patsy13 on December 16, 2010, 10:00:35 PM
I am restoring a 1948 Plymouth with a factory installed P-18 engine.  I plan on replacing a tired fuel pump with a new one.
I have read in the Plymouth Owner's Bulletin that several members have had problems with after market fuel pumps.  It seems that
the pin that the operating arm pivots on seems to be the problem with some horrific results. 
Does anyone have a particular brand or supplier or rebuilder that is reliable that I can use???
I have a spare pump that is rebuildable.

You can rebuild it yourself with a kit from Antique Auto Parts Cellar. Or have them rebuild it for you.

If you choose to rebuild the pump yourself, that is the only way you can be assured that the pin is properly installed. Any pump that I purchase now is checked to see if the pin will hold. If it is loose, I pean (sp) the ends with a punch so that it is secure. Good luck!

Basically the pin is immproperly straked and it walks out leaving the arm with no fulcrum.  You can assure the straking is proper or fabricate a sheet metal  clip that will assure the pin can not come out.  Or you might be able to find a spring clip at the hardwaqre that will keep the pin from moving.

As your bit of exceedingly trivial trivia for today, the 'traditional custom and usage' for the second vowel in 'pein' or 'peen' relates to the context in which it is used.

As an apparent generality...........when used as an adjective, describing a working tip of a hammer, the spelling 'pein' seems to have been preferred by those who wrote the old supply house catalogues, i.e., 'straight pein', 'cross pein', or 'ball pein'. Sometimes the term will be 'hyphenated', as 'cross-pein', etc. That is probably an older usage, now falling out of favour, except, possibly, as 'trade jargon' in the smithing  community.

A modern supply house catalogue is likely to list only 'ball peen' hammers, sometimes given as ballpeen'.

When used as a verb, as in 'peen all rivets to a radius approximating that of the rivet head', a customary usage has been 'peen'.

Many old technical writers chose 'peen', 'peening', or 'peened' to refer to the act of displacing metal by striking the metal with a hammer, in the context of rivetting (and 'rivetting' is yet another variable usage, with some preferring a single 't', as 'riveting') to form rivets, or 'peening', e. g., to tension a saw blade.

Thanks for hammering home the gramatic reality of the term.  Another explanation from the dictionary of Knighthood and Chivilry dictionary:
Knighthood & Chivalry Dictionary

To secure a rivet into place by hammering . A mushroom of the rivet material is formed and the materials to be joined trapped in between the rivet head and the mushroom. A round face is used to make the shape, and sometimes if a soft material is to be secured to a hard one (such as a leather strap to a piece of armour) then a rough washer might be cut and placed under the mushroom side of the rivet.

Perhaps you could clear up a couple more thing for me.

Is it Further or Farther?

And if someone can be described as disgruntled, how come you never hear of a person being gruntled and why is disgruntled used to describe one's condition, as its form is past tense and in and of itself implies a former state or feeling.

Farther/further - in informal English the two words are interchangeable with the tendency to use further becoming more frequent. In formal English some people make a distinction with farther being used when describing distance. ("He went farther on his antique car tour than I did.") Further is used to explain degrees of quantity and abstract relationships. ("He went further than other club members in his efforts to help restore the antique car.")

This discussion is just begging for a Jeff Foxworthy explanation of the English language....
