Fuel pump leaking

[grizzlebar]

Need some help and tapatalk search isn’t being useful at the moment.

 

Started my car in the first time in what feels like forever and noticed a small leak coming from the bottom of the fuel pump. Can anyone point me in the right direction of what to look for? Can these pumps be rebuilt?

I'd start with the hoses/clamps.

Checked them, both right and dry underneath

I can’t tell from the picture weather that is crimped-on type or  a serviceable one, which has a bolt in the center of pump

This has a small slotted screw

I'm only familiar with older style which had a replaceable diaphragm.

These are not horribly expense parts, given their importance. Hard to see what kind of pump you have from your pic, but perhaps (if this is the kind of pump you can disassemble) your have a problem with the seal around your pump filter.

The pump you picture looks like the sealed variety used on later cars.  They can't be rebuilt, but before pitching it, stuff a big dry rag underneath the pump to catch any gas that runs out, then unscrew the fastener in the middle of the pump's filter cover. 

 

Underneath you'll find (surprise!) a filter screen.  The cover has a seal (cork or a big rubber O-ring).  Make sure that cover seal (or a loose cover) isn't the source of your gas leak before discarding the pump.  But if the leak is from the crimped seam or anywhere else but that cover, it's new pump time. 

 

The pump is conveniently placed so that gas dripping from the pump will drip on the alternator, an excellent source of sparks.  And we all know what air + gas + sparks equal:  in this case, external combustion...

In BMWs case it was a new car sale. Planned obsolescence (or destruction).

Perhaps time to consider electric pump.

I wonder how long this mechanical pump has been in service. Although I have read about it happening, I have never had or observed one fail. Installing an electric pump is a non-trivial undertaking (if done correctly/safely), provides no performance improvement and they seem to have a substantially higher failure rate. I have no statistics on this- just anecdotal info from postings here and elsewhere over the years

New pump ordered and should be here Saturday, thanks Blunt.

Is this as simple as unbolt the old and put in the new?

Well aside from the small leak it still works like a champ

I may take my old one apart and see if I can reseal it.

Sometime in the future I’m going to probably be going the Holley EFI route, so this pump is just to get me to that point.

which pump did you order?

Long neck, according to Steve
