Fuel fittings

[mechanic190]

I'm curious. I work at a heavy duty truck dealership and we use the plastic fuel/air lines and compression fittings all the time. Now I'm trying to plumb in my drag race fuel system with 1/2 aluminum tubing for fuel line. Is there any reason I couldn't use brass 1/2 compression fittings with the 1/2" aluminum fuel line?

nope - none that I can think of.. except for weight - I wonder if there is a sanctioning body rule though.. best to read your rule book first.. hell, go with black aluminum and brass fittings - be dang cool looking

That would be sweet looking but I already have the natural aluminum tube and only a couple an fittings and on a budget lol

I used them to adapt mine to AN, been on for several years with no issue.

Alright great to know. I am probably only gonna run an from the cell and the rest will be compression fittings and then regulator to carb will be an. That'll save a lot of money compared to buying new an fittings for every connection at fuel pump filter regulator ect.

Link to specific example?

Because there are MANY types of compression fittings, and MOST of them I would NOT use on fuel, most especially aluminum.

Don't have a link but I'm talking about the ones that you can get from Napa heavy duty. Trucks use them with air lines and fuel lines

Update *** she works no leaks. Spent 45 dollars in brass compression fittings to pipe thread. 7.50 average between 6 fittings. Easier than flaring tubing to fit the an or buying an fittings and then the adapters from tube to an that use the same compression fittings anyway
