On electric fuel pumps with 5/16's fittings what is a good way to connect it to a 1/4" gas line?

Use fuel proof rubber hose and worm type clamps. If you use the Airtex pump from C&G it is supplied with hose barb fittings. If your pump doesn't have them, most good auto supply stores do. The 1/4 inch hose will fit the barbs and the original line.

I believe that anyone messing with fuel or brake lines should own a double-flaring tool. They aren't expensive, and they allow you to do professional work. In the case of installing hoses to rigid fuel lines, I've found that using the above-referenced tool will allow you to make an effective "barb" on a steel line by using the first-stage die, but not following it up with the final flare. When you install the hose, install the clamp "upstream" of the bulge you have created.

This Airtex electric pump came with 5/16 hose barbs and short pieces of 5/16 hose. Are you saying that I should hose clamp those 5/16 hoses on the !/4" fuel line?

All hoses and fluid-carrying piping and tubing are rated by the inside diameter. Thus, a 1/4 inch metal non-structural tube will measure 1/4 inch inside, and will measure that bore plus it's wall thickness is times 2 on the outside. A 5/16" nominally rated hose due to the thickness of the rubber is very close to a 1/4 inch metal fluid-carrying tube's outside diameter given the thickness of the tubing. I have qualified the above so as to not confuse "fluid-carrying" and "structural". Structural tubing is rated by the outside diameter. So....for example, a 2-inch 1/4" wall piece of structural tubing would be rated as a 1-1/2 inch pipe if it was used in that application. This message was edited by Stroker on 11-26-11 @ 4:43 PM

Dan, may I inject a simple yes on your behalf? LOL Alan

Alan: You may, and after re-reading my overly verbose and mainly irrelevant reply, I'll try to concentrate on the questions more in the future. "Yes" would have been sufficient. Thanks for the guidance! Dan

I just assumed that Airtex provides a 5/16" barbed fittings because they assume that is the diameter size of most fuel lines and they did not take into account that early Fords are 1/4". I was just going to swap out to 1/4" barbed ends with the 1/8" pipe that fit into pump inlet and outlet,you can get brass ones instead of the steel ones Airtex supplies.

I used 1/4" gas line and hand forced, which streched OK, the end over the 5/16" fuel pump fitting. Worked fine. Wardb
