Day 2 parts discussion

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Hemicolt</div><div class="ubbcode-body">I was always under the impression that the color differences were to indicate the gph rates. Red being the low end,
blue in the middle and the black pump being the highest rating. But that system may be something that was put into
place in the 1980's or after.
However, I would agree that the pump should be at least 1970's based on the body design and America decal. Dave will
probably educate us in a bit.
Also, what are thoughts on using an early pump with todays fuel? I was probably going to use a new
pump and paint it blue all over and apply one of the decals on the bracket. Unless of course one of the old ones will work. </div></div>

I was told years ago that the only difference between the red and blue pumps was the spring in the bypass. My car had a blue pump on it when I bought it in 1985. It went bad and I replaced it with a red pump around 1986. I swapped the spring out of the blue pump into the red pump. It worked just like the blue pump did for many years. I had to replace it in 2004 when it started leaking really bad. So I bought a new blue pump and it weighed about half as much as the old blue pump. The new pump lasted about 2 years before it started overheating and quitting. Nothing changed except the pump so it wasn't wiring or fuel line location.

Rust in and on the tank could have changed in two years. You could try to put a magnet on the tank at the lowest point,with tape,it can help{low cost try}.

Love this day 2 engine .. Reminds me that the day two look was and is about going faster making it your own /standing out and having fun doing it ..

Thanks Dave. I'm just being hopeful that I find something with a 1969 date.

Carter was another well know brand used in 1969.

Also just noticed the bracket in my earlier NOS red pump and the nos blue one on ebay PXTX posted is silver plated while the later pumps- mid 70's had a gold cadmium plated bracket. Cool little differences.

Here is the replacement pump I got from Holley, the blue one. It was rated at 14 pounds pressure and required the regulator. The earlier (very much new) red one let me down at an IHRA points meet when it would only pump when it was cool. My original one was red, but now 40 years later I'm shocked to find that my Holley rep would have lied to me about the color change thing (sneaky old salesmen anyway). At this late date I can't recall if the red one had the regulator or not. Anyway, this pump is what I used from around 1972 on, on many of my drag race stocker and not so stock racers. The bracket appears to be of the silver variety underneath the layer of &quot;patina&quot;.

Here is a picture of the rubber in a new style Holley pump. Would anyone care to remove the bottom plate on one of the old ones and see if it's the same? If so, I could get a nos pump and buy the rebuild kit for the rubber piece.

Red one was non adjustable and never came with a regulator. It really was just a electric version of a stock OEM mechanical pump with some extra gph boost.

Wow, another one painted all blue....really an early one.

Since I was working part time at a local friendly speed shop, I got it warrantied directly by the Holley rep. I'd never compared paint jobs or bracket colors before and was suprised when I pulled if off a basement shelf and saw that it had been all blue originally and had the silver mounting bracket. No, I'm really not a packrat or anything..... [img]<<GRAEMLIN_URL>>/no.gif[/img]

This is the regulator that came with the first Holley fuel pump I ever bought. A red one that I purchased and raced with in the '70s.
