David Tweet Posted November 12, 2020 Report Share Posted November 12, 2020 Existing was 3/16th tank to pump to carb. All new brakes etc.,now fuel line...Thought I'd just reduce when at pump and carb but not finding reducer, not the move. . Guessing it's different pump with 5/16th inlet/outlet? Go back to 3/16th? Have one old reducer was at tank, male 5/16th to tank, female 3/16th that the line connected to. It's just not right eh? Thanks, Appreciate the input and site, couldn't have got this far without y'all.! Quote Link to comment Share on other sites More sharing options...
Tooljunkie Posted November 12, 2020 Report Share Posted November 12, 2020 No way it was 3/16”. 1/4” maybe. Style of fitting at tank would help. Quote Link to comment Share on other sites More sharing options...

Countryss Posted November 12, 2020 Report Share Posted November 12, 2020 Just did mine. 5/16 all the way tank to carb. Got a 25'coil and had 3 connections at the tank, midway on rail, and at fuel pump Quote Link to comment Share on other sites More sharing options...
squirebill Posted November 12, 2020 Report Share Posted November 12, 2020 Tubing is measured by it's outside diameter. Pipe is measured by it's inside diameter. Are you going by the inside or outside diameter? 3/16 OD tubing seems very small for a fuel line. 1/4 inch OD tubing would have an ID close to 3/16 inch. Just saying.

Slickster Posted November 12, 2020 Report Share Posted November 12, 2020 Yeah. 5/16.... Quote Link to comment Share on other sites More sharing options...
David Tweet Posted November 12, 2020 Author Report Share Posted November 12, 2020 Hello, Yes its 3/16. I just hand formed all brake and oil lines (5/16,1/4, 3/16),new cylinders,relined shoes,painted frame etc... .the fitting at the tank was a reducer, 5/16 male threads into tank, female accepts 3/16 line. It ran like that for years, I think I need carb/pump with 5/16 in/outlets. Don't know why they did it but can't leave it as I'm bringing back to stock! Ha it's always something eh!
