It looks like something like this is on there now. http://www.zip-corvette.com/catalog/...uel-pump-hose/
I know it says 64-69 but u get the idea.

Well I finally had time to get underneath it and the
main source of fuel on the floor seems to be coming from the vicinity of the fuel pump. Something I noticed though is everything in this side of engine compartment and rear ward seems to have a fine layer of oil on it except the fuel pump. Possible a seal went out on old fuel pump spraying area with oil and it was replaced and now a seal is leaking fuel? I still couldnt find the point source of the fuel except maybe where the pump is attached to the block but not sure....

I've seen this oil spray problem before. The oil might be coming from the bolt hole at the top of the fuel pump that is used to install a new fuel pump. Check to see if the bolt is missing.

There are two holes in the passenger side front of the engine. The top bolt hole will align with the fuel pump push rod and should have a 3/8" x 3/4" bolt in it. If the bolt is missing you will get oil spray on the passengers side of the motor.

When you install a new fuel pump the bolt needs to be removed and a longer 3/8" bolt installed in its place. The longer bolt is to gently hold the fuel pump push rod in the retracted position.

Hope that helps.

I have heard of that and ill look but two questions. How much oil would u lose u think? I've driven it 200 miles and the oil level isn't low. Second, would there be fuel mixed with the oil? Fuel is my main thing in finding under the car. Thanks.

If the bolt is missing the oil lose will be very minimal, just enough to make a mess of the right side of the engine bay but not enough to show up on the dip stick in 200 miles. Maybe a half quart of oil every 5000 miles.

The good news is it takes two minutes to check if that's your issue and another two minutes to fix if that is the problem.

The missing bolt is an oil issue only and not a fuel issue.

I'm about 99% sure this is where the bolts are supposed to be but I figured I'd post just to be sure. You only mentioned the top hole what about the bottom?

The bottom hole is a blind accessory hole that's ok as is. In the top hole you can see the fuel pump pushrod, that hole needs a short bolt to plug it, but not interfere with the pushrod operation.

Can I just get the bolt at a hardware store or do I have to go to an auto shop? Sorry for being a noob I just don't want to screw anything up.

3/8-16 coarse thread by 5/8 or 3/4 long will do, hardware grade is fine. Do not use a lock washer, it may leak a little past the threads and the split in the washer. Just user a bolt with no washer will work fine.
