TPi Fuel Lines

Guys, need some help finding o-rings for the fuel line from the flex lines to fuel rail and new replacement flex fuel lines for my TPI. Called Advance, Napa, and Jegs with no success. The primary line is 3/8" and the return line is 5/16".

Re: TPi Fuel Lines

I had new flex lines made at a local House of Hose for about $20. I brought them the fitting and they pressed on hoses and set me up with new o rings that were fuel rated. good luck!

Re: TPi Fuel Lines

I need help! I need to know what's the size of O-ring number 224. I have tried three times and each time the fuel line leaked. I'm tired of driving around looking for the right O-ring. I'm banging my freaking head against the wall in frustration.

Re: TPi Fuel Lines

I was under the impression that the Fuel O-rings were metric. 14mm for the return, 16mm for the input side. I bought a kit that had all of the orings iincluded on-line. Usually can get them on Ebay for about $10 for the kit.

So just to be sure the one I'm looking for is the return o-ring correct? Ima go ahead and make a quick stop by Auto Zone one of these guys mentioned Viton and Auto Zone carries those.
