Fuel filter question

[Yummi]

I have a fule filter on the pressure side of the fuel pump - mounted in a well, crappy fashion with zip ties.  I also have one before the pump.  No real issues there. 

After the upcoming night ride, I am planing on pulling the motor and having the transmission gone through just so I know it is all fresh.  Figure that would be a good time to rework the silly filter. 

Will this filter work after the pump?  Figure it is about 90#'s of pressure or so.  Also, how the heck do you tell what size AN fitting you have?  To mount this in a proper fashion it will require two 90's and some longer fuel line.  (I will have to turn it 90* from current to have filter mount to frame rail)

If it helps, it appears to be an 11/16" fitting, although for the life of me I cannot find an 11/16" open end wrench.

Wait, did some digging - might have answered my own questions.....  Looks like -6

IMO ,a good paper element type filter such as you linked ,used BEFORE the pump is the only filter needed. A filter after the pump is ,IMO, useless.

I am hearing that you should only use a screen filter before the pump.  That a paper fuel filter will suck out and plug the pump and injectors.  Just something I read on another site.  and no I do not believe everything that I read or hear.    Just saying

I've never had any issue in 30+ years. Just don't use a junk element.

I mean IF it's going to suck shit through/from the filter it will just as easily(actually more easily as a pump is more efficient at pumping than pulling) push it through to the injectors. I see no difference except that a filter placed before the pump will protect the pump where a screen affords almost no pump protection.

Might be something to that Fast.  As most any late model car has screen before fuel pump and filter on the pressure side.

keep the rocks out of your tank guys and also the pickup should not at the very bottom either. Need somewhere for any small amount of condensation/water to pool without entering fuel system.

I know the "correct" place for a paper filter is after the pump. However I have had small debris get past screen and lock up a pump. After that I used a paper element filter before the pump with no ill effects. AND no more locked up pumps either. Only reason I know of for not using a paper filter before the pump is due to pressure drop that in a high demand application COULD cause vapor locking. For most of us tho i doubt that will ever be the case unless we use a dinky too small pump in the first place. Just my 2 cents.
