Fuel Pump Hat

I wanted to share this, since there are a lot of people out there with fuel pump issues that might want to keep an eye out for this when servicing your fuel pump.

Last weekend, I was driving along busy hwy 41, and The Mark began to gasp like it was out of fuel (I had 3/4 full tank) and just died while I was going up a hill. Coasted off to the side of the road and tried to restart. It would sputter for a split second, and die again. Did this numerous times, with the same results.

Just so happened that Aric and Ryan were coming home from the lake, and saw The Mark on the side of the road. They pulled over and tried to get it going with no luck.

Side note... I had it flat bed towed to Aric's, which was about 5 miles away. I did not know it at the time, but the tow truck guy wrapped his winch cable around the intercooler pipe under the car, and bent the piss out of one tube. lol I guess Aric has those silicone couplers on that car real good now. :) Going to see if I can get Cody, my PDR friend to pull the dent out of the tube. If not, back to Joey Bell to weld in a new tube.

Anyway, Aric did all the normal checks, and it lead him to the fuel pump. Now I have a less than two year old Ford GT supercar fuel pump, along with a KB BAP in The Mark, and found it very hard to believe that it petered out already, especially since I barely drive the car. So, he drops the tank, and discovers that part of a O-ring inside the stock Mark fuel pump hat has disintegrated, resulting in lowering pressure in the fuel line.

To fix the problem, he completely removed the stock Mark fuel pump hat, and used new tank lines clamped directly the the pump. I picked it up yesterday, and it ran great! :)
 
Good info..thanks!.. we're dropping the tank this week to install the new gears... I'll have it checked out.
 
No, I have not gotten a quote yet. Here is a pic of the dent

Looks more like he attached a hook to the control arm area and the cable did that. Pretty narly though! I like Boss's idea though, lol.
 
Plasma cut the dent out and trace and cut a patch and weld it in places. I hate lazy tow truck drivers, I spent two hours once with one at the shop helping him put a lambo on his truck so he did not damage the car. He did not want to wait to find out how the tow hook in the front attached, but I got it done. Good find on the o ring , I had similar problem before in a few cars.
 
Well, PDR is not going to work, so I talked to Joey Bell yesterday - http://www.bellchassisworks.com/ He's the guy that did all the awesome intercooler tube work on The Mark. He is working on a couple cars for the Southern Nationals drag race this weekend, and is already booked for next week. Looks like he can't get to The Mark until the week of the 24th to repair the tube dent.
