So I have a 98 Dodge RAM 1500, 5.2L. I want to add in a spin on fuel filter water separator. Its got 3/8" NPT threads for the inlet out outlet. I figured I could remove the braided line up by the transmission and do a short braided hose to the filter and then a new one up to the fuel rails. Will this work? If so can you link me to some line and fittings or do I need to take my truck somewhere to have this done?

 

Anybody have any ideas? Here's the filter.

 

Well after some research it looks like I'm going this route. I'm gonna pick a nice easy to get to spot on the frame under the cab where the steel fuel line runs. Gonna cut it, put these "no-flare" compression fittings on the old fuel line and the new little section of fuel line, I will bend the new steel section of fuel line with a tube bender out to match up with the filter inlet/outlet and then use a flaring tool to flare the other end and use a tube nut to screw into the filter. Should work great!

I'm just gonna buy this kit, comes with everything I need.


Also while I was browsing for fittings i found these, would work great on the transmission lines when you cut the check valve out and add an inline filter or aux cooler.

Fuel filter I'm using. Note: Derale makes one but the filtering micron size is higher and the max pressure is lower.

Also since I mentioned the transmission compression fittings here is a tranny in-line filter.

 

Add a reply if you want me to do a write up on both the fuel filter and tranny filter and have them put as a DIY or something.

 

I thought about doing this also, but I would add a regulator also and get rid of the stock regulator/filter that's in the top of the fuel pump.

 

Filter is on the bottom right before the pump not in the regulator.

 

The filter/separator you're looking at is shown mounted upstream of the pump (suction side)... if you install it down stream of the pump (use the stock pump in the tank), make sure the filter, hose, and fittings are good for our rail pressure (49psi) plus a good safety factor.

If you're replacing the stock pump, you need to include a regulator as well as the filter and pump.

 

Yeah I noticed that. To that make a pump without a regulator that goes in the tank and I would put a regulator after or do I just need something to go down in the tank and then a pump and filter outside of the tank. Or should I just leave it like it is?

 

Just leave it like it is. The additional filter isn't going to help you at all, and installing it is gonna be complicated. (read that: Expensive.)

 

The Second Gen fuel pump assy is basically a 3-stage filter. There is the sock at the bottom of the pump to filter large debris; then there is the internal filter; and finally, the pressure regulator acts as the third stage.
