I have a new in tank sender with fuel pump assembly that came shipped with the long nylon filter BUT with the filter not attached. The flange on the pump is like the receiving end of a funnel and the filter has a plastic retainer inside the filter with a hole that is of course smaller than the pump receiving flange.

My problem is that no matter how I try, I cannot get the filter with that smaller hole over that sharp edged pump flange.

 

If you measure the diameter of the flange where the filter sits and compare it to the opening on the filter,if fairly close you may need to place the filter in some heated water to allow it to flex /stretch some and slip over the flange. Then when it cools it would be tight and make a good seal.

 

After sleeping on it so to speak, and examining the sender/pump assembly closely... comparing it with my cleaned old assembly which originally was so thickly coated with stale gas, gunk, whatever, I found that the filter has a brass cup which is factory sealed to the still unfolded filter with a seating washer (such as a brass grommet), after which the filter in folded into its usable position and sealed.

I found that the filters are readily available at any automotive store in this area. My new pump simply came with the brass cup installed and it was impossible to assemble it without the factory equipment. The cure was to remove that brass cup and install the newly locally purchased filter to the sender/pump assembly.

I encountered a new problem... the fuel return pipe requires a rubber type check valve which is of course missing. Nobody in the Valrico, Brandon, Tampa, Fl area has this check valve, including the Ford dealerships.

I have just sent off a five page letter with pictures to JC Whitney (customer service) about this problem via priority mail explaining how a small rubber valve is stopping me from completing this project. No doubt drop shipping is involved from elsewhere... they need to look into their quality control section.

 

I just today received a reply via snail mail from JC Whitney of 761 Progress Parkway, LaSalle, Illinois. Their reply is dated June 28, 2013 and appears to be postmarked 07/01/2013. Their reply states... "We received your correspondence regarding the missing Check Valve. We contacted the manufactuer of the Fuel Pump Hanger Assembly, and unfortunately that part is not included on the product. However, we do offer universal ones on our website by size. If you should have further questions or concerns please feel free to contact us back at 1-800-529-4486. We apologize for any inconvenience."

This is via a form letter whereas they can insert a short note with no signature from anyone... simply a typed form signature that states:"JC Whitney Mailroom". Obviously I'm not too happy with their service. I take the translation of their note to say that the problem is not their fault and they can't be bothered to make it right, and if I want to get that side tank installed, buy some check valves and return the ones that doesn't fit. They couldn't be bothered to send a few valves, have me pick one and trust me to send the others back.

Bottom line, big question... Does that check valve absolutely need to be on that return line in the tank?

 

YES !
The reason for the check valve is to prevent the fuel line to the injectors from draining back to the tank and causing a hard start condition while the pump has to run to fill the lines each time they drain back.
You could google a place called ,"Vintage Parts USA".
They just might have what you're looking for.

 

I believe that perhaps there is a misunderstanding here. It is just a rubber flapper type valve that allows fuel to exit whatever pipe it is attached to and to prevent fuel from entering the pipe.

The check valve would be on the "Return Line" and its design would be to allow entry to the fuel tank and to prevent the fuel in the tank from entering that return line it is attached to.

The outgoing fuel line has the large nylon filter attached to it. I assume that the built in tank pump has its internal checks to prevent backwards fuel flow?

The possible misunderstanding leaves me still somewhat confused.

 

I've been trying for days on end to find that rubber check valve to no avail.

The return pipe it goes on is 5/16" in diameter. The filter is about 15/16" long, pictured here.



Would anyone know where I can find it... or what the Ford part number of it?

 

Joe,
I realize you have been going through a lot of trouble to locate a particular part, but www. vintage parts usa should be able to help you. They may even have the entire fuel pump assy. At least check them out and save their info for any future parts you can't get or locate anywhere else. Anytime I needed a part for an older Ford that the dealer no longer could get , they had it !

 

I was at that site but had a problem getting around on it. Perhaps I was just tired out. I'll go back again and really lean on the search.

Should you be there for any reason and spot it, please let me know. I'm about ready to put this entire assembly together without that valve just to see what happens... a lot of work for a 80 year old guy to go thru twice if it doesn't work out so hopefully that site has it.

I appreciate your time my friend.

 

Joe, I just spoke with the folks at Vintage parts. They have a toll free phone number- !-877-846-8243.
They will sell to you ,but you must have a part number and that you should be able to get from your Ford dealer parts dept. I don't know if you will get a # for the rubber piece you seek, but you may need to purchase the entire fuel pump assy which should eliminate the problem of gambling with individual parts.
I know you already purchased a pump assy , but it came with problems that you didn't expect. Sometimes we need to start from scratch and hopefully get the right parts the first time. There is always the salvage yard that may have the special parts you need.
