I replaced my fuel pump with the Holley Black the other day and I did a stupid thing. I took off the stock fuel pump bracket. Little did I realize that there was a hole back there that led to the oil pan. I tightened the bolts down, but there is a small leak. After running at 70 mph for 15-20 mins, and letting the truck sit for about 3 hours, there is a puddle under the truck about the size of your palm. I was curious if it was hurting anything. Do we have a crankcase ventilation system? If we do, is this affecting it? Whenever I get about 30 or 45 mins free, I'm going to tighten it. I was just curious if it was hurting anything in the mean time. I have plenty of oil in it so that's not an issue. Thanks.

 

Cut the old pump part off the mount and rebolt the bracket back on to stop the leak. yes there is an oil hole there.<br> Danny

 

BigBlue:

As long as you didn't lose oil pressure, I don't think that you hurt anything. The crankcase is vented, hence the infamous crankcase vent tube. Other more mechanically inclined brethren than I can respond, but I think you are OK if the oil pressure didn't take a dive.

By the way, how's your fuel pressure with the new lift pump?

None of the Holley pumps are approved for diesel. I had looked into getting the red one for my '85 F350, when I found out about the Holley pumps.

 

FP sucks. Only seeing 9.4 at idle versus 13.4. The only one that would work for our trucks is the black cause it is a continuous flow. Rod said he has had a couple of complaints about bad pumps. When I talked to Summit about it, they said the line was to big and the pump couldn't flow enough fuel to fill it (1/2&quot; ID line). When I talked to Holley, they said it was mounted in the wrong spot. I think they are both full of crap. I'm going to take out as much of the excess line as I can and make the fuel flow as straight as possible and see if that helps. I cut about a foot off today of the line going to the inlet of the pump and raised the pressure a solid 1psi. So maybe if I take off a little more, I can get more pressure. I'll let yall know what happened. The oil pressure hasn't taken a dive so it's no big deal. Just an annoying oil spot.
