100 micron pre pump fuel filter, 75 front pump location Options

[rfinegan]

I am looking to route my fuel lines one more time (no kinks). While in there I will change my line to AN fittings and braided fuel lines. Does any one have a recommendation for a Pre fuel filter of 100 microns? I have a good post hi pressure filter in place already

Something like this?

As to “ NO pre pump filter aside from the tank screen” I have wondered why this is a good idea. Suppose that screen get clogged up: And your out on an open road ?

No screen at all is also an acceptable (and possibly preferable) option. This is how it was done on Vanagons.

You want the least amount of restriction pre pump. Shortest, fatest, straightest suction lines possible with no filters restricting flow. Vacuum on the inlet side of the pump can cavitate the fuel which leads to a noisier fuel pump as well as potentially causing damage/shorter life to the pump. Depending on the condition and routing of the fuel lines it can also cause the feed line to collapse on itself causing fuel starvation.

Injectors require filtered fuel for long life the pump doesn't, it needs unrestricted fuel flow.
