I have a spool of 10 guage which I'll use to power the pump. It also has a 10 or 15 amp fuse (whatever the instructions called for). I'm going to wire up a relay soon.



Get this; I'm using all three 1/4" tubes Y'd together as sending lines. One was the original sending, one was return, and one was a tank breather. It's got a fuel cell which uses a different type of breather, so I figured three quarters equals at least a 5/16" if not close to a 3/8" in flowing ability. It does seem to flow quite well from what I've seen during testing. What do you think?

Make sure your relay connections are tight and very secure. I have a nice melted relay sitting here that resulted from inadequate contact (excessive contact resistance leads to heating, which loosens the terminal, repeating the cycle). Well it was controlling a big pump.... If you have the proper relay socket, that's much better than crimp terminals.

10 wg is fine.

I'm assuming this is for a carb setup with no return? I suppose Y-ing the lines is okay, just maybe a little messy. And the feed line is only 1/4"? I thought those were always 5/16".

he's got a glc, the stock engine is so weak that they almost dont need a feed line....

Precisely!

Nope, thats the vent/check valve for the fuel tank. It keeps the tank pressure close to atmospheric pressure. Dont block this off. If the valve is bad, either replace it, or bypass it by connecting a pipe between the hoses. You dont want fuel fumes accumulating in that area so they need to be vented appropriately.

Ah-hah!



That makes sense! Rest assured it is back where it came from...
