Help - my fuel pump is leaking

Today while changing oil in my 1960 Vette I noticed my fuel pump was leaking, although very slightly as a slight mist was building up along the bottom of the fuel pump and onto the rubber fuel hose that connects to the fuel pump.

My fuel pump is only 3 or 4 years of age. It is a generic fuel pump I picked up at Canadian Tire and probably made in China.... Yeah I know you get what you pay for... ;-)

The fuel pump appears to be leaking along the flange that joins the top half of the fuel pump to the bottom half.Has anyone else had this problem with generic fuel pumps? Can anyone recommend a good replacement fuel pump that is not known to have this problem along the flange that joins the two haves of the fuel pump?

Thanks kindly...

Kenmo

edelbrock holley

I would get an edelbrock holley or even a gm performance (jegs) all $70-100. They all have that gasket. The bolts at bottom may be lose or gasket went bad from heat. An 80gph if under 300hp but a 110gph would be fine for over or under. Fix it quick I lost a 76 vet to a small fuell leak (best thing to ever happen to that car).

You dont have much room get the holley 80 or even a carter. Carter might be your best bet.

Doc here,

YUP!!!!

Had it happen on an 80 Vette..

Right on the band crimp.

For every gallon that went to the carb..1 gallon went out the hole...(at least before I found it..)

Bad part was it was pointed right at the headers and plug wires

Doc

If I remember correctly, 'Vettes of that vintage used Carter WCFB carbs. Be very cautious with the pump that you use. It's easy to overpower the needle and seat and cause a fire that will burn the car to the ground.

A pump which will produce 5 1/4 to 6 lbs of fuel pressure is all you need. Any more than that will cause problems.

I replaced the Carter carb with an Edelbrock street performer carb and manifold. The Edelbrock looks exactly like the old Carter AFB.

Plenty of NEW original GM issued fuel pumps on eBay ... for reasonable money.

This one is listed as the correct one for a 1960 Corvette ... cannot beat original GM for fit and the correct application in my book.



BUY IT NOW for 32 dollars with $8.95 shipping

This is NOT my auction, I do not know the eBay seller and have no financial interest in the transaction ...

Also any suggestions for proper rubber fuel hose? The rubber hoses I am using are marked "SAE fuel/emission 30R7 Goodyear" ... This is the second rubber hose I've had to replace in an year. The rubber that attaches to the pump is very soft. The rest of the hose is fine. I suppose the gas dripping down on the outside caused the hose to get soft...BUT... I thought this would not happen to a fuel hose? Shouldn't it be able to handle contact with gas on the outside of the hose?

Any suggestions for a good rubber fuel hose?


Again thanks...

Kenmo

Yeah, take it off and sling it as far as you can. Replace it with hard line properly formed. Non-metallic fuel line is to be used for connection purposes only.

Well that is where I'm using the rubber hose, as a connection. It is connecting the cooper gas line to the the fuel pump.... The fuel line from the pump to the carb is steel except the short piece between the carb and gas filter.

Copper line will fatigue and crack over time as a result of vibration and flexing with the motor rocking on the mounts. Replace it with steel line. Been there, done that.
