Fuel line bends Building a new frame for my '39 and during the fuel line install I ran across a potential problem. While putting the filter in I connected it with a 90 degree fitting. Will this cause problems with pressure/flow? The engine is a stock 5.3, filter is stock '03 GM and lines are Dorman nylon. By the way, I like the Dorman tool to make up this lines. Ends up cheaper than my old way of 3/8" brake line and F.I. hose.

the steel fitting you have with the nylon fuel line? The steel fitting seems to me like a better choice over the plastic parts

Fuel lines Thanks for reassuring me regarding elbows and pressure. Only have the one 90 degree so I should be fine...I think.
All the fittings will be steel except the 90 degree one pictured. I get my steel fittings from the junkyard which have steel "fingers" on the inside for a positive lock. I have read on other post that the nylon fittings sometimes come loose (aftermarket stuff) so OEM is best. To remove the nylon line from the steel fittings that I get in the junkyard I use a heat gun and pull. Don't use a razor blade because it will scratch the steel and may leak. To put the line on I put the nylon line in the sun (use new line) and oil the steel fitting. Once started, make sure the line is going on straight. Mine have slipped right on nicely and gives a warm fuzzy feeling about the connection.
