toying around with the idea of replacing the stock plastic fuel lines with steelbraided (from tank to fuel rails). Has anyone done this, if so, any pitfalls you can save me from? list of needed fittings would be great. Would -6 be to big?

 

Pushing this up. Has anyone replaced the fuelines in their truck from gas tank/s forward with socketless or steelbraided lines?

 

I am thinking about doing this as well. but I have one question you say the current lines are plastic? I have steel lines from frame to fuel rail and rubber with steel braid over them from frame to tank.

Edit: I have a 93' F250 extended cab long bed 351W

 

If the truck is running okay then why spend money on something that will add little to no value?

 

RLA, The truck is almost 30 yrs old and the motor and tranny are out. Right now is the best time do do all the little things (not that running fuel lines is a little thing). I have a really pretty motor going in. Flashy paint, beautiful aluminum bits, I will upload the build once its done, but since I am replacing all the vacuum, coolant, Smog, and dolling up the electrical when I convert to MAF I figure why leave well enough alone. My fuel rail is going to need lines and conversion fittings to the quick release, I was thinking why stop there, why not save money on the fittings, buy 15 feet more hose and go all the way back. Problem as I see it is 2 things. AN or NPT conversion needed at reservoir or some sort of aftermarket option that has threaded ends, and plumbing from both tanks.

Right now build is as follows:
351w 9:1 compression
Custom grind RV cam
Edelbrock manifold
BBK throttlebody
Procomp Cast Iron 202 heads (cleaned up, portmatched, Valve work)
Mallory Ignition and distributor
96 Bronco MAF conversion with harness sensor and injectors
Quarterhorse software for tuning.

Tranny is getting rebuilt with all the current e40d goodies.

This truck is ugly as ****, but its my "Hotrod" and I enjoy working on it, so the added value is definitely there.



DBD,
My fuel lines are a plastic,nylon composite, appear to be pretty thin walled and run all they way back to the reservoir. From there it looks like thick walled rubber.

 

Your truck has a fuel reservoir mounted on the driver side frame rail? I thought Ford stopped using the 3-pump system in 1989?

 

Could be the selector valve, I havent been able to locate that one yet, but its as big as a coffee mug, assumed this was the reservoir. Either way, I got a lot of standard hose connections that would make converting to socketless fittings difficult. Which brings us full circle to my original question (rare a tangent will do that) Has anyone done it?

 

Sorry to keep going off topic here....there is no selector valve on a 1990 and up gas engine F-series.

Assuming you have dual tanks then the dual function reservoir would look like this:


A single tank vehicle would have a reservoir like this:


But my impression was Ford stopped using that system after 1989.

Once again, sorry for the hijack!

 

IS there something WRONG with the plastic lines?

If not, you putting steel in will only DOWNGRADE them

I say leave it be

 

In the engine compartment as dress-up? Sure, why not. Anywhere else where they will never be seen, why bother. The plastic will be just fine.

 

yeah, I suppose we will go with the lines will be just fine. Although that was not my concern.

And yeah, i thought it was a reservoir, top one is mine.
