Has anyone used hydraulic compression fittings on a hard fuel line ?
I have an 8mm O/D steel fuel pipe which I intend to use an 8L male compression fitting (nut and olive ) with a 3/8 Hose tail which will then have a double braided PTFE swaged hose on it to my tank mounted fuel regulator/pump this end will also be a swaged fitting
Hose and fittings are more than adequate pressure wise
Just wondered what everyone’s thoughts were on this

I do that all the time when doing engine conversions, never had a problem. I repair Merc SLS lines with them to.

Might be a bit overkill but won’t do any harm. More than adequate and if using PTFE flexibles you’ll be fine. If using normal rubber hydraulic hose on fuel lines I’d be wary - check the hose spec. PTFE is chemically inert so fine.

Aces, thanks for your advice I was quite relieved when I found it was 8mm o/d steel pipe as I have metric compression fittings on the shelf at work, il make the hose etc up tomorrow, not looking forward to dropping the tank though it’s 3/4 full |

I use compression fittings but dislike having the end of the tube "dangling". I make fuel blocks which can be bolted down, no risk of movement then . looks better too imo.

Thanks for the advice, oh yeah it’s belt and braces with a ratchet strap around your waist haha I’m using the hyd fittings etc as it’s what I work with so it’s readily available |
