Racor 790R30 primary filter

While looking for the items needed to put new fuel lines and update/relocate my primary fuel filter, I located the Racor 790R30 filter assembly for only 205.00 on Amazon from Fluid Power Products. This is a bargain. Most other places I have sourced it from ranged from $329.00 to $475.00. If you are even contemplating doing this change over, I wouldn't hesitate to purchase. They show only 3 left. Hope this helps someone.

I just got a PM from another member saying he couldn't find the item. If someone else locates this, please give a shout out as to where and how. I know that he would like to get one, and I ordered from my phone, don't know how to retrace the product # or whatever would locate this for him.

Go to the Racor Store Home page and you should find the 790R30.

I stand corrected. I received my filter today. It is a 690r30 not the 790 model. When I went back to my order, I found my mistake. The picture is of a 790 but the print is a 690. Ordered from my phone without reading the fine print, my bad, just not sure if I will keep this one or send it back. In my zeal for a great buy, I spoke incorrectly. I apologize for the confusion.

It looks as if the 690 series doesn't have the electric priming pump. If it doesn't then I would recommend returning it. I consider the priming pump to be essential.

That is correct David. No priming pump and no water sensor. I agree with the priming pump, for me it is one of the must haves. If I'm going to do this, then it is going to be right the first time.

Our CAT 3208T has a manual priming pump and the Cat people recommend that you prime the engine before starting if it has been idle for some time.  I use 30 days for my idle purposes, as I recall, 60 days is too many and can result in hard starting.  Manual pump seems fine, don't think you "need" an electric.  In any event, in my opinion, you need a priming pump of some kind.    Have a great day  ----  Fritz

Thanks Fritz. I agree I need the priming pump. Really like the electric after using the Winn. Just my opinion though.

Really, my 3208 will fire up up in less than Mississippi 1, even if it set for 6 months. Best starting motor I have ever owned.

PHRED  ----  I don't doubt that it would start easily, guess I've just never wanted to try it since it is so easy to prime it.  I don't go much beyond a month between starts, but maybe some time I'll try a longer period if situations warrant such.  The 3208 is ,as you know, a really good starting engine.  Have a great day  ----  Fritz

CAT rules! Our 3116 had been sitting at the pier since October. Went to move sites; no 'priming'; started RIGHT NOW, as per usual!  b^.^d

Our Cummins M11 also doesn't require priming under normal circumstances--even if it's been a few months since it was started. However, when we change filters it is certainly nice to have the electric priming pump!

Priming really depends  on engine brand and model.

Some have a  simple manual primer pump-- very KISS.

Some have a separate electric pump.

Some have an engine-manufacturer supplied electric pump (Cummins ISL for example).  Just install the filter dry and cycle the key a couple of times to prime.

Again, NO "here is how they all work".  Just learn how YOUR system works.

 I guess for me, after finally learning about how to prime the engine, I am spoiled to the electric primer. Nothing wrong with a manual primer either, I'm sure. I just know that after changing out the starter last year, if I can get the engine to start with less cranking, I expect the starter to last longer and I will be infinitely happier ;D

Hopefully when I have the fuel lines changed and the new primary filter system, my Cummins will start as easy as you Cat's do  ^.^d

In my entire lifetime I have never experienced a motor that would start as fast as a cat 3208 period. This includes gasoline engines. Less than one second.  Have no idea what voodoo magic on  how it's done.

The Magic is that the 3208 Cat was a mechanical direct injection injector pump engine.  Very simple and very effective. They start instantly.  All the current crop of diesels are "common rail" fuel systems with the injectors powered either electronically or by engine oil pressure.  They have to spin long enough for oil pressure to come up before start can occur.
You can thank the EPA for that one.  Simple and effective was changed to complex, expensive, and trouble prone.  Go figure.

I would challenge you with my 1981 International DT466 it even has a mechanical shutoff. Hit the button and try to release before it starts is a skill.
