DIY : PTFE line- tank to HPFP + inline fuel filter upgrade

[Erichale77]

I'm sure it has to do with flow AND pressure.

Is anybody Else delate the hpfp Filter and add a Inline Filter Like Steven and i do ?

Post pics

I'm going to get in on this too. I have an ethanol sensor in place already with upgraded fuel lines. When I adapt that to the flex-fuel system I will put in a new filter then remove the one from the hpfp.

just to show you guys how restrictive the line is on the bends

Unless I missed the post.Do you have parts breakdown on replacing the line with sensor?i plan on replacing from lpfp to hpfp with the DIY here but also want to get rid of the restrictive turns too that connects to hpfp.

This is what I used but use it at your own risk

Should only be installed by a competent mechanic

HPFP Adapter 171-06-14-BLK
Sensor adapter 140-06-BLK
Push lock hose adapters x2 401-06-BLK
30cm of aeroquip 3/8 fuel line depending where your connection is and type
Thread sealer or gas plumbers tape for the sensor

[martymil]

[Erichale77]

I'm using same set up. Works great. Thanks Martymil!

 

[martymil]

I like the op's ptfe setup might use this for my new setup but the new kryptalon from aeroflow hose

Extremely flexible but very expensive

Question, can you show me a photo of the female fitting which has the cone inside? The HPFP inlet is M14 1.5? What angle is the cone inside? I have a pair of these for my shotgun but they are separate inserts, ferrules or whatever they are called.

I saw this, but that is not right, you're missing the cone inside? There is no seal without the cone I think.

It has an inverted flare. Works fine on my car. That pic is not the right fitting.

Ah okay if someone can post a photo of the item? I'm curious for a different reason.

 

[martymil]

171-06-14-BLK Looks like that

If your going to put this fitting on the shotgun make sure you use a mild locktight on the thread as it vibrates a lot and it can come off

I think most of us can use a short course in “Fittings 101”.

(I used to work in a chemical engineering lab many years ago, where we had many boxes and containers and catalogs of all different kinds of fittings for different purposes. It seemed that there was a lot of hit and miss rummaging around in the parts bin. It’s amazing I didn’t blow anything up!)
