I had this issue with the original fuel filter housing on my Duetto about 4 years ago. The nipple was just leaking and did not fall out. I don't know it the nipple is 'swedged' into the housing or 'cast' into it but I believe it was swedged and wonder if ethanol dissolved a sealant causing it to leak.

I like Gordon's solution; tried to fix mine with a torch and that did not work (housing melted). A used replacement is a good option.

My car has an aftermarket electric fuel pump and that nipple now has the same issue....

You know exactly what I mean and exactly what you are doing.
Careful. You're on VERY thin ice with some of your comments.

Yes, but what did you end up doing to secure the barb in the housing?

Had the exact same issue with my FISPA fuel filter housing on my Duetto and used JB Weld to seal/reset the barb. Been almost year now that this was done without additional issue.

JB Weld is terrific stuff. I have the same issue on a FISPA fitting where it leaks between the casting and fitting. I found an earlier version that has a screw in barb fitting. No leaks. I did have Gordon's thought to thread the fitting but lack the machining ability.

Update, fixed the hose back in place and as suspected, the pump kept squirting the gas out (busted diaphram...).
Spent the better part of last week looking for fuel pump, gave up on exact 4033 match, but got a hold of a couple of new FISPA 4059... not sure if the rod will 'sit' properly though... from the photos it looks like the FISPA 4033 will be tilted some 10mm inwards, whereas the 4059 ones I bought seem to sit flush along the edge... thoughts anyone???

The only 'deep throat' I could find locally... used and abused... not good... diaphram has a life expectancy of 15 - 17 years and the silicon gasket spread on this thing looks like left overs from the cuban missile crisis...

Got my rebuilt pump back today from Then and Now Automotive. They tapped and threaded in a new hose barb where the original had come out, fitted a new ethanol-resistant diaphram, and replaced miscellaneous other pieces. Sent it off on Tuesday and got it back on Saturday, along with 2 gaskets, one for between the pump and the spacer and the other for between the spacer and the engine. Pics below.

Sbadaro - you might want to contact them about a rebuild kit for your pump.

Glad things worked out for you. The new unused Fispa 4059 with the cam flysh to the surface threw out the spring in protest and I didn't want to shorten the rod nor did I have a wider spacer to tinker with, so I ended up putting the used replacement pump pictured above... it works... not sure for how long...
I'll fight going to electric pump as long as I can and will try replacing diaphram from the broken 4059 on the old original pump... look for 'jp weld' or locktight something to put it back together without leaks... original parts becoming more precious by the minute...
