I would suggest You call Airtex Customer Service Tech Line. If You google Airtex Customer Service they have a 1-800 #. I would be interested to know what they tell You. I just got an Airtex Pump from Rock Auto like the One You have. Debating if I should to pay the return Cost and lose the Shipping Cost I paid or take a Chance and keep it.

  

I would not use a pump that I could not install with just one hand pushing up on the pump and the other installing one of the bolts.  As far as the fuel pumps with the glass sediment bowls are concerned , some are designed for use with a filter and some are just a sediment bowl with the screen.  I have seen both, but can not say as to what either one came on originally.  I am using a 390 FE pump on my y-block with 3 '94 carbs, and a 428 pump for my yet to be installed 313 C.I. 2x4 y-block..

I appreciate the offer Gene, it's something on the back burner tho definitely not a priority. On a whim after you mentioned it, I looked on eBay, at Viton sheet. Then, I found a whole passle of fuel pump rebuild kits, supposedly made with ethanol tolerant materials. These rebuild kits are about double the cost of an FE pump with filter, n order to install the old style pump have to probably rebend fuel line, install an inline filter, and then add the cost of the kit, etc. Heck with all that. Must be gettin' old!

My flathead pump and carb rebuilder responded:

oldcarmark,  One of the first things I did after receiving the Airtex pump was to place it on the bench and work the arm. As I mentioned earlier, the force required to depress the arm seemed  like roughly five times that of the old pump. It did occur to me that this much force could damage the eccentric on the cam (as well as possible accelerated wear on the front cam bearing).  However everything is relative and this arm force, although difficult to overcome by hand, is much less than that caused by a single valve spring.  Yes, the arm was under (not on top of) the eccentric. Also, the eccentric was placed at its uppermost position by rotating the engine . I did not have any trouble re-installing the old pump as well as an extra used pump I have. Both of these pumps had much less arm force than the Airtek. The old pump I had in the car was presenting fuel starvation on heavy acceleration or speed above 60. I tested it before removing it and it tested 5 psi (normal), but only about half the specified flow rate. This is what's so puzzling. It seems like the pump pressure would be relative to the diaphragm spring stiffness.  Both the old pump and the Airtek tested at 5 psi, yet the Airtek pump has much more resistance at the arm.

Not a problem, I'm always amazed at the websites that are out there that you guys know about, they just don't seem to pop up in the intertube search motors anymore the way they once did. They went from "most relevent" to "most $$$" some years ago.

I thought they had fuel pump parts, but apparently not. I apologize. 
I have sent an email to another source, I'll let you know when I hear from him.

Howdy all,

I replaced the mechanical fuel pump on my Mercruiser 454 V-8 in 2006 with an Airtex pump (the Mercruiser OEM btw)

All it's ever had is E10 fuel.  It still runs just fine.  I think you may find that Airtex is the OEM for many fuel pumps out there in radio land......
I would I would think that anyone with a defective Airtex pump simply got a defective pump.   That doesn't make them all defective IMHO.....
When I buy the new pump for my 292, if I don't go to an electric, it'll be an Airtex.

I just replaced the fuel pump on my 223 six and it claimed to be Ethanol fuel compatible. I'm hoping the Airtex on my Y is also but who knows.

Gene, those are carburetor kits near as I can tell. Do they have fuel pump kits?
