Question

[Jdog]

After my alarm has been sounding, we got the main gas tank filled and put a new fuel water seperator on, but coming from the engine to the fuel filter. someone installed a small tank and put a after market blue fuel line with a clip on hand pump bulb, so i had to reroute the fuel line from the engine to the fuel filter in order to use my main gas tank. my question is should their be a brass fitting with the clip on hand pump bulb or should the fuel line go to the hand pump bulb with out the brass fitting>?
Or do i even need the hand pump bulb?

is this why i am getting fuel restriction alarm?
it seems to come on when the engine warms up and i rev the engine.

here is a pic of the fitting that i am talking about.

The alarm may be because one of the fuel lines is collapsing when the engine is calling for more fuel. This is a perfect scenario of what ethanol does to fuel systems. The bulb is to prime the engine and you do need it there.

You'll see a lot of addon fuel fittings like that on boats. Usually it's when the owner wants extra range. You have portable tanks that you can just clip onto that fitting for the extra fuel.
I agree with Cam, I'd look at/replace my hoses.
