& when you put it there & it gets clogged the first time - drop the tank!

One thing I've leared to do is drop the tank on any car that's been sitting & have it boiled...
.....hmmm, did I put that in "Awakening a Sleeping B"?
Son-of-a-gun, I did!

Right now I probably have the cleanest gas tank on any non-running 1984 Alfa Spider! /ubbthreads/images/graemlins/thumbsup.gif

Kenny - that's because I had it boiled
take your empty gas tank to a radiator repair shop...that's who does mine.

The bottom of your fuel pickup doesn't have a screen?

Hi Tony,
No, my original tank did not have a screen & the new Moss replacement didn't either. With the Healey fuel pickups welded in as they are, You would have to cut the pickup out to clean the screen.
Interesting story - I replaced my original tank with a steel Moss tank. Mind you, I live in a dry climate & keep the tank full most of the time. Anyhow, about a year later, on a long road trip of course, the front inline filter plugged. Bypassed it until I could get a replacement filter at the next town. Popped the tops off the carbs & the bottom of the bowls were covered with red powder, about 1/8" deep, that had gotten in just in the couple of hours that I ran with no filter. Pretty sure it was starting to plug the jets as the car was starting to run lean & pulling the chokes let the stuff go through. This stuff went right through the built in SU pump screen. Cleaned the carbs, put in the new filter & all was well.
Got back home & cut the plugged filter open. It was filled with red powder. Looked in the tank & the surfaces were coated with red powder. This in a one year old tank. Never near moist air. Maybe the gas/alcohol mix that comes out of some pumps attracts water. Put a very large inline filter (Fram G3802A) between tank & pump. Replaced the front filter again & carry spares of both on trips. The tank hasn't gotten any worse or any better. The rear filter can hold a lot of rust powder. No more fuel starvation problems.
I'm sure that the older US made tanks were galvanized inside. The Brit tanks I got sure weren't. My mistake. If I ever change tanks, the next one will for sure be aluminum.
So you are correct, if the tank is clean & stays that way, no filter should be needed. I don't think I will have this tank "boiled" every six months & don't trust coatings.

Think I will stop by the local radiator shop tomorrow and see what they say about boiling tank. I took the fuel sender unit out today and the end of the float was just pealed right off, nasty thing. When I looked in I saw both clean metal and splotchs of something? No telling what.

The regulator in the pic is a high quality Holley unit. It has one inlet & two outlets. The outlets can be plumbed separately to two carbs, or one outlet plugged, or one outlet run via a restrictor back to the tank for fuel recirculation, or a pressure gage attached.
Sort of overkill on a small engine, but very good on large high power engines. Much higher quality than the garden variety pressure regulator.
They come in two pressure ranges, 1-4 & 4.5-9 psi. The low pressure model would be the only one useful for your application. You can see them here:

I knew if I got you to post a pic, someone would ID it...
Now that we've identified the problem, step 2 is fixing it. /ubbthreads/images/graemlins/jester.gif

Guys, don't always assume that the red powder is rust coming from YOUR gas tank. I pulled my Bronco in to an Amoco station to fuel up, (a station that I used all the time), and fortunately I was headed home. As I pulled in the drive It quit! Reason was found that the station had just had its tanks filled and a red powder, which was rust stirred up from the bottom of the tanks, was mixed with the grade of gas I was using and I think that 95% of it went to my pump and really messed up my fuel system. How it got through the filter I could never figure out as the carb, a 4 barrel, had about an 1/8th of an inch of the stuff in the bottom. It's usually a situation beyond your control, but what a mess to clean up. It doesn't happen to often anymore as most gas stations are using fiberglass tanks.

I can't believe it took me until recently to find this site. What a great amount of resources to get help from.
You hit the nail on the head Dave when you suggested that the regulator was probably attached to a pressure gauge. I took a look under the drivers side dash and there was a pressure gauge tucked away underneath. It looks to me that one of the former owners wanted to soup up the car as they did some weird modifications like jacking up the leaf springs and painting alot of the chrome black(What were they
thinking?)
Anyway I have to figure out why my new SU Pump isn't drawing any gas now. I took of the inlet from the tank and it was as dry as a bone.
Thanks everyone.
Gary.

Gas in the tank? Has it been sitting a while?
On mine, the screen filter on the pickup tube was covered with a nearly glassy looking dry gas varnish so bad that you couldn't blow through the tube. Took lots of carb-cleaner, and very careful scraping to clean it off.
