Squirting fuel pump
Ran out of gas the other day but got home OK (that's another story). Fuel tank not leaking and fuel line OK. Put fuel in the tank but when I started her up and looked under the hood, there were powerful squirts coming out of the top of the fuel pump!! On close examination, the fuel was coming out of a small (1/4") hole in the "dome" casting at the top of the pump. This hole points towards the back of the truck. The hole has no threads. Now I know where my $45 worth of fuel went....bugger!
Should there be a plug in that hole or is this a breather hole? A new pump at NAPA is $70 so I'd prefer to fix the old one since it is working.
Can anyone help? Advice please. Thank you in advance.

Thank you gentlemen.... I notice the pump seems to be sealed up and not rebuildable like the really old ones. Seems a shame that the diaphragm isn't replaceable. I'll fix it this weekend and change the oil at the same time.
Cheers!

Not trying to hi-jack this or anything, but what about oil on top of the fuel pump? The oil seems to be appearing from the pump itself? The block above and around the pump is dry, so the gasket doesn't seem to be leaking. The oil seems to be coming from a metal ring around the middle of the pump. This ring looks like it holds the upper, and lower halves together. The pump is about 2 months old.

wb6vvv: I'm driving down to Seattle and then Portland next week. You say that Edelbrock and Carter pumps are available in 'racing stores". Since the price of a regular pump is about $70 up here in Vancouver, do you know of a store in Washington/Oregon I could contact to see if they have a good quality pump that would work on my 460? I wonder if one of those X style pumps that were on hi perf 429 Mustangs would fit? The X style pumps are rebuildable. Thanks for your comments.
PS - I don't mind buying a Chinese junk pump (sorry for the pun) but it should cost about $7 max, not $70.

You can order them right on the Internet. Just go to Summitracing.com and order it. The Holley pump for the 460 is HLY-12-460-11 and is around $90.00. The Edelbrock is EDL-1726 and is around $120.00. You can buy repair kits for both of these pumps. I have seen the Edelbrock for $100.00 in several racing stores. You can do a search on the Internet and might find them cheaper. Also note that these are 110gph high performance pumps. The pumps you buy at the local auto parts are probably 50% of that flow and sometimes less. You get a heck of a lot better pump for $20 or $30.00 more.
