One piece gas line

drbarbara · #1 07-05-2008, 08:49 PM

Following everyones advice I was trying to change my gas line to a steel line. The problem I ran into probably has a very simple solution but I just can't find it. The size of the fitting on the Holley carburator is a 1/4" and the one on the pump is 5/16". I got a pice of 1/4 line and a piece of 5/16' line but could not find a reducing fitting to join both of them so for the time being I was forced to join them using a small piece of marine grade fuel rubber line though this I think defeats the purpose of the steel line. I looked for the connection in marine store, auto part store and hardware store. Any ideas.

Here is a small clip where you can see the line with the rubber hose.

Any ideas?

Thanks

Try a plumbing supply house or heat and air.

How about using 1/4" line and bushing it down at the pump. You've gotta be able to find a 5/16" male X 1/4" female bushing and adapt to the flare fitting from there (I think).

Good luck with it.

Carry your pieces with you and tell em what you want to do, they will fix you up.

How bad is it to leave it like this until I can sort this out. I mean is the risk big or small. I understand that you want a steel line because you do not want it to rupture. If the hose is new can I assume that it will be ok at least for a couple of weeks?

I change all to rubber, just leve a short piece to the carb to double clamp the rubber, and end al the problems!!

I see you have an actual marine carb now, that one ought to work nicely. I personally would be looking for stainless line, if you can't find it then use coast guard approved marine grade rubber line. It may not be completely legal, but it works just fine on outboards. Just find some hose barb fittings that fit into your pump and then your carb, and run at least a 5/16" line. HOLLEYS are notorious for starving for fuel under load. 1/4" will not feed that carb under a hard load and could cause you to lean out and burn a piston. Use brass fittings with an extra long barb on them and double clamp with marine grade hose(DON'T USE AUTO HOSE!, you'll be begging for a problem). And the filter after the pump is for in case you have a pump failure or a piece of the diaphram comes loose it won't cause the needle and seat to stick open and allow raw fuel to spill out.
