3.6 Fuel Pressure problem solved, The return line Options

[RON S.]

A couple days ago I posted a question about a fuel problem on my car in that when first cranked, the car would run fine bu after a couple of minutes the fuel pressure would begin to swing up and down, and eventually drop so low that the car would stall.

At first I blamed the suction line to the pump, maybe being clogged, and then maybe the pump failing.
Well today I ran the car will a hose in a gas can and it still had the same problem. So, I took the filler neck of the tank for a look inside and saw what looked like a piece of rubber stopping up the return line.

So, I drained the tank, and took the line barb off, and presto. a completely plugged return line.

I'm glad you found your issue. A plugged return line makes perfect sense.

On the tank note, I don't believe anyone makes repro tanks, but I do know that there are better tank sealing kits. I've used Kream (which looks like the Eastwood kit) and it worked horribly.

McMark recommended a kit by Caswell Platings which has worked really well for me on a few tanks. Its essentially an epoxy, not the paint-like coating of other kits and it seems to adhere extremely well. I've used it on both steel and Al tanks with great success; the stuff is literally as tough as nails.
