Is there something else that has to be done when adding an inline filter? I just added a FRAM PH8A filter, unhooked the fuel lines from the inlet of the fuel pump in the valley of the engine and jumped it over to my filter. No my computer says lack of fuel pressure?
Any help... Thanks

 

Having a hard time visualizing this one, bud. You got the fuel bowl in front of valley, but the pump itself is down below d/s door, inside the frame..

 

The only fuel pump I have is the factory one on the top of the engine. there is no pump on the frame.
I put a FRAM PH8A filter inline before the factory pump, but it seems to be too hard for the pump to pull the fuel threw the FRAM filter.

 

apologize, was thinking that you had a 99-03 7.3 truck..

I'd say, remove the filter and see what happens. Maybe, the filter is too small of micron rating. I wouldnt put anything under a 30micron, before pump, without a "helper" pump.

 

How did you route the hose? The lines might have kinked causing too much restriction. Secondly the PH8A is an oil filter...not a fuel filter. Different media and micron ratings are different. Fuel filters are single pass, oil filters are multipass. I would dump the fram IMHO.

 

I dont know what single or multipass means?

There was deff not a kink in my hose. But the hose I used might be too soft and could have sucked close? I was wondering if I should put it after the pump?
Anyway the truck has been running great since I took the filter off, I was just trying to get something a little more better and cheaper for filtering.

 

Per SAE J1985 single pass filtration efficiency measures how efficient a filter stop particulates at one pass of the fluid through the filter.

Multi-pass measures the efficiency when the fluid gets circulated multiple times.

Single pass ratings make more sense with a fuel filter since at least some of the fuel will only see the filter once, while oil (or trans fluid or coolant etc etc) will see the filter many times in the relatively closed environment.

A better bet would be a Baldwin BF1311 filter head and a BF1212 fuel filter pre-pump.
