My Walbro is too short-HELP!!!

[meanchicken]

I know...sounds like a personal problem...but it's a mechanical one.

I dropped my fuel tank, pulled off the old original fuel pump, started to install the Walbro..and it's about 3/4" shorter than the old pump.
The numbers on the walbro (bought from Turbotweak) are:
F20000169
23407-2

The problem it creates is that the OEM piece that the pump plugs into is not long enough to stay securely plugged in between the walbro nipple and the nippe on the sending unit poutlet tube.

Am I supposed to reuse this rather important looking OEM piece, or replace it with the rubber hose that came witht the Walbro?

Get rid of the OEM piece.. .and use the hose.

I have that pump from Gbody as well, works great.

I cut off the restriction on the metal hose as well... rubber hose should be long enough to cover the removal of the plastic pulsator, and restriction.

The oem piece you refer to is called a pulsator. Remove it and discard. Use the hose provided with the kit. Make sure you cut off the neck down portion on the hard line. This is the section that was inserted into the pulsator and is clearly smaller than the rest of the metal line. Place the pump on the hanger in the proper position and trim the hose to the correct lenght.

So...I've discovered that the rather important looking piece that fits between the fuel pump and the outlet tube of the sending unit has a rather important name....it is called a pulsator.

Gee...I sure hope it's not important ...cuz...rrrr... I'm an idiot:redface: and I did what any idiot in a hurry would do...I deleted it and replaced it with a section of rubber hose from my Walbro kit. The instructions told me the pump could be installed this way....while they didn't tell me to go and delete the pulsator...they encouraged me to, so I'm gonna blame the instructions....

...Cuz I'm an idiot....

I have it all back together now.
The car started up fine and idled fine....In a few minutes after I get outa my working clothes and into some cruisin clothes, I'm gonna go for a spin.

Stop me if I'm about to explode or something.

Now you tell me....
I was typing my "I'm an idiot..." story while you replied to my first note.

Well...
While I did not cut off the smaller diameter section of the hard line, I did slide the hose up over it pretty good.
But the hose clamp is over the smaller diameter section.

Well...if the bugger blows off, I guess I'll find out, but the fuel pump is cradled in there pretty good, so I don't see it blowing off.

 

[Madcat455]

It won't blow off. Only reason to cut it off is to improve flow.

If your not going all out with the car, you probably won't ever notice.

Thanks.

Sooner or later I'll have to drop the tank again to change the sending unit (still works now, but I know they fail at some point), so when that day comes, I'll make the mod on the output tube of the new sending unit before installing it.

Thanks for this post, just sitting here searching on "fuel pump too short". Would be really helpful if there were a sheet of paper in the packet that spells out what to do. A part of the instructions actually states that the hose is not always used so I dismissed it. Thanks again,

i bought one of those pumps...took only a few days to become so damn loud and me so paranoid i took it out.

Laying in bed thinking I need to bench test prior to install
Hoping I have no issues

Had you conferred w/ your uncle Lou, you would have not had this "issue"...

Probably make a mess doing it that way...........

Well pump is in and tank is back in place.
Off to gas station to get some fuel and see if the new pump solved my fuel pressure issues. If not, then on to regulator.
