Just an FYI, if you are using an SPI fuel filters and AV gas, STOP. The inner tubing of the SPI filter hose reacts badly when subjected to AV gas. The tubing swells and chokes off the fuel flow.
Slash found this out a a year or two ago. He had me come over to his work place to show me. He'd cut the filter off and handed me just the hose portion and said try to blow through this, it was very difficult to blow any air through that hose.
I don't know if actual race gas makes them swell or not.
Nope it's some other hose, boost it used a different pine and filter. I now installed a g2s filter. Hose its self is fine, I think it's a good year hose.
Been in contact with tj since day one of the issue and we've gone through it all so far and are getting thin on ideas it seems lol, I created this post to reel in more thoughts and suggestions on the issue.Have you spoken with Neil or TJ at Boost-it ? They are really good at figuring these things out.
