searching for the cause of my high fuel pressure i took out the tank, blew out the hoses in the tunnel, cleaned them with a coat hanger, no obstructions, no gunky build up.noticed when i removed the fuel return connection on the tank, the new epoxy hole on the inside was about 1/2 the diameter as the port itself. approx the size of a drinking straw (1/4") as opposed to about 5/8" could this be causing the high pressure?
question 2 po had fuel pump hot wired to the coil ( no ground wire) is there any way of picking up power from the fuse box or relay so i do bbq the car? moving the pump up to the front and don't think i can snake a wire thru the tunnel. original harness wires are not in the original spot

Sup Chef.

You can tap power off of your relay board on the drivers side where it orriginally came from. Pin 13 of the 14 pin connector on the forward most plug. It is the pin most forward and outboard. Ground is just to the chassis.

Oh and yes a blockage of that size could definetly increase your pressure. Think about it, 5/8 vs 1/4 is a difference of 2.5 times. If it were an artery you would definetly be feeling it. Time to take out the small round file and remove some of the excess epoxy being carful not to rub through to the metal. Clean up and retry.

Easy enough, you probably have a spare inthe board. You can use one from the headlights to test it if you want. I know someone near you has to have spares.

No problemo el chefo.

Run a long wire to the coil and when I see you we can shorten it to the board. I will provide the relay.

Chef, did you ever verify if your gauge was shot or not?

Thinking about your shrinkage of hole, I don't recal there being a 5/8" port, only a bung perhaps of such size under your tank.

(IMG:style_emoticons/default/agree.gif) pics would help

Hey Rich,
I think that that is why Mark was asking for pics. IIRC, the hole there is normal (been a while since I looked at it). I guess I was expecting something of a protuberance in the hole making it smaller.

So to recap:
-tank passages clear (check)
-Return line clear (check)
-Fuel pressure gauge busted (check?)

Other than the potentially erroneous fuel pressure readings from a bad gauge, what other symptoms did you have? You mentioned it ran great and that it may have been smoking (maybe rich, maybe oil, maybe valves). Your answers will lead us to the more correct course of action. It appears at this point that we have not conclusively proven that there is a fuel pressure problem.

(IMG:style_emoticons/default/agree.gif) with Pete, if time permits I want to come up tere and help out.

Here's a top view. Old tank that was resealed. Return line comes up under the baffle, which is the other hole you see when you look through from the bottom...

Sorry Dr. but I disagree, it doesn't seem to me that the tank passages are clear especially the return one. The return fitting is tapered at the end, but the passage itself is a nice clear hole, doesn't look that way to me. It's hard to tell from the picture but is there even a hole there any more, or is it completely blocked by the epoxy?

While you're at it Chef, change the fuel screen from the other fuel port, the epoxy probably screwed up that thing also.

The red car pictured is a Maserati Spyder, the poor man's Ferrari (IMG:style_emoticons/default/biggrin.gif)

Edit: From the previous picture I'm not sure anymore if what I'm saying is correct, maybe there are variations in the gas tank design (IMG:style_emoticons/default/confused24.gif)

Mine looks like that and I am ASSUMING that the good chef checked the passage for clarity.

Heck Rich, you should be able to see/hear the fuel returing to the tank with the pump on and a little gas in the there.
