I have a Frantz fuel filter being collecting dust for a while, and am thinking of install it again. I am not sure if my 2003 Toyota Echo's fuel pump is powerful enough to push the fuel through the TP after the stock fuel filter. Does anyone know the minimum pressure needed to push fuel thru a TP in a Frantz filter?
How much fuel pressure needed for Frantz filter?

BTW, the stock fuel filter housing is an integral part of the fuel pump assembly, which can be replaced but not removed. The best I can do is to try to remove the filtering element inside the housing. Not sure if this can be done. I am concerned the fuel pump may die from working too hard if I daisy chained the bypass filter with the stock one.
The following is a quote from Ralph Wood at the location Discussion of fuel filters
I also remember reading a post by him about one engine where the fuel pump could not generate the pressure needed to push the diesel through the tp, but switching to a softer type of tissue worked. But, I can't find that post back again.
By gassers, I assume he means gas engines.

My Camry fuel pump can handle the Motor Guard. I have the Motor Guard on a few Ford Powerstrokes. The Motor Guard can handle vacuum so I can pull the fuel thru the filter to protect the fuel pump. I would think any of the TP filters would be about the same. The dirty end of the TP is turning grey and isn't penetrating into the TP over 1/4". I might have to use a softer roll than the Scott 1000 sheet such as Kleenex Cottonelle. Always use a secondary filter with TP filters.
I have a sintered bronze filter at the outlet of the Motor Guard. On the Legacy I put the Motor Guard between the pump and the outlet of the Motor Guard. On the Legacy I put the Motor Guard between the pump and the stock fuel filter. On a 6.0 Powerstroke I put the Motor Guard between the pump and the tank. The Motor Guard keeps both stock filters clean. Your stock fuel filter doesn't restrict the fuel. That's why is doesn't clean fuel as good as the TP. The Motor Guard is less restrictive for fuel because the element isn't close to the outlet. Motor Guard didn't plan it that way but when they opened up the filter to be less restrictive to air flow they also made them less restrictive to fuel. Any restriction should be in the element.

Here's a test I did with the Frantz, as used with the stock Cummins lift pump on a Dodge pickup:

I currently have that filter used on my '02 Dodge, but also have an added Carter "pusher pump" installed for better fuel flow/pressure.

Since my Echo's fuel pump and stock fuel filter locate inside the gas tank, the Frantz filter will have to be installed between the fuel pump/stock filter and the engine. Unfortunately this setup will not prolong the life of stock fuel filter. Changing the stock fuel filter inside the gas tank is really time consuming and expensive.
I do not understand why installing a bypass filter does not eliminate the need of stock fuel filter.

Not familiar with the Echo fuel system. I always like to have some type of filter downstream of the TP filters in case I get something large on the wrong side of the TP. It is easy with my Camry because the stock filter is under the hood with the Motor Guard. AT one time I eliminated the stock filter and added a sintered bronze nipple filter at the outlet of the Motor Guard.

For the appearance the Frantz fuel filter does not look any different from the other Frantz filter beside the label on the canister. It came with hose that can handle fuel.
The old Frantzes took a standard 0-ring. I have heard that they have changed the 0-ring size. For the Motor Guard I get my 0-rings from www.mcmaster.com. 4 5/8" by 4 7/8" by 1/8" dash 247, catalog number 9464K48.
I have had some trouble on marine engines with the buna-n swelling. Buna-n is the recommended material for oil and fuel. Sometimes the Viton is better. It is also more expensive.
It has been more than 10 years since I have sold the Frantz. I seem to remember 4 1/8" by 4 3/8" for the old Frantzes. Don't hold me to that. About 20 years ago a guy wanted a new 0-ring for an old Frantz that was an odd ball and I had to order it from Frantz. It was about a 61 model.

"How is the gasoline Frantz filter different from a regular Frantz, or are they the same? Do you need a different gasket?"
The fuel filters come with a 3/8 inch hose and fittings, and the restrictor orifice as used for the oil bypass filters is eliminated to permit maximum flow thru the TP element. The basic filter looks otherwise identical to the oil bypass unit.
