In the process of removing my old fuel pump the plastic nipple, sleeve, and o-ring came off. I looked at the order first, but now that it is time to put in a new pump I'm starting to second guess myself. The order that I remember is that the plastic sleeve went on first, then the o-ring, then the plastic nipple - is that right? I've searched and read through the service manual and parts index - I can't find a close up view of how it all goes together.

Thanks in advance,

I second that question.

 

spacer, then o ring , then plastic cap. nipple facing up on the plastic cap. this is of couse from the fuel pump to the pipe. not pipe to the fuel pump.

 

Thanks Twisted7. Did I get this right? Does that last plastic piece actually snap onto the fuel pump?

Edit - OK this looks like it will actually fit. Can someone confirm whether or not the last plastic piece snaps on or not?

 

no it doesnt. when you put it up into the pipe it will hold it there from the spacer, that will lock into the pipe.

 

while we are on this fuel pump installation post...I have a dumb question:

The pump's terminals are submerged in gasoline...would that a fire hazard?

 

I am pretty sure gasoline is not conductive, but i think ethanol might be. (Don't some places mix ethenol in with the gasoine?) i'd like to be more useful here but i have to change an RX7 fuel pump. I might do that this winter.

While you're at it, some people use brass tools to ensure there are no sparks when working on the fuel tank. Sparks could be bad.

 

once youve removed the fuel hoses and cover.. swap is done away from the tank..
make sure the work area is well ventilated..
