Default Inline filter on fuel line to rail

I'm replacing the quick disconnect and 5/16 fuel line that enters the rear of my fuel rail. Is there any reason NOT to install a small filter?

Make sure it's not so small it restricts flow, and make sure the filter and the connectors can handle the pressure. It's 40-50 psi, depending on the year. Your average garden equipment plastic filter isn't going to cut it.

1. Fuel is filtered already near the tank, it then flows thru stainless steel pipes and rubber hose, which are not going to add any contaminates to the fuel.
2. Added filter gives another leak source, another connection.
3. a leak in an engine bay filter is a bad thing given all the ignition wires and hot stuff in there.
4. Why??????

I say in big letters...NO.

Now maybe some are smarter than me and I am wrong

It's probably big enough, but you still have to deal with the connections. Hose clamps are not going to get the job done at all. Really, I don't see much benefit, and I do see more potential for gas links.

Hmm. Where would you put it? A big metal canister near the exhaust manifolds sounds like a good way to boil your gas. That's not going to end well.

I'm with Cruiser. Just don't.

I used it to join the old line to the new line and fitting. its right up top next to the intake manifold where the stock bracket was.

OK, you done it, let us see a picture so we can assess the safety of the install at the least. There is no stock fuel filter bracket near the intake, so I am clueless as to what you have done, again a photo please!

Good luck!

Note from DJ

If you crawled underneath your Jeep just before the driver’s side rear tire and look up where the frame starts down after the high spot where the frame goes over the axle.
If is like my 88 there will be a small black football shaped object which will be connected between rubber hoses that will be your existing fuel filter.

I know there is a fuel filter already. This was just to connect the lines. There was nothing else at the store in stock I could have picked in a pinch. Pictures incoming.

The dark spot is from the old leak. It hasn't leaked so far. I'm waiting on a whole set of fuel lines to come in the mail.

Don't leave the parts store rubber lines and filter on there any longer than the new ones coming in... Here's my buddies vehicle only days after he "fixed" it exactly as you did back there at the rear of the engine...It sprung a leak and kept pumping the fuel, went up quick even after shutdown..

If parts store fuel line can't be trusted, then which fuel line can I trust? Am I supposed to trust the part store fuel line soft/hard "oem" stuff I ordered from the same shop? Honestly doesn't this come down to proper professional installation vs bad inexperienced installation?

I was referring to the stock fuel line bracket mounted to the side of the manifold.

Rubber fuel line isn't rated to handle the pressure of a fuel injected car. We're talking about 50 psi. It's intended for low pressure applications of a carbureted car, where you are looking at pressures under 10 psi.

It will most likely leak at the clamps.
