when I did my 84 (same as 83 I think) i didn't find a Moeller that was quite right. fill & vents are in wrong place. Took the old one to Atlantic Welding Bayville, NJ. They matched the outside dimensions but didn't write them on the receipt, sorry. They did use thicker aluminum and added more baffles so it went from a 60 gal to a 57 gal.

Don't forget. the tank compartment is designed to be a dry space. It does not drain to bilge! always SEAL the hatch!

I don't mind dropping into the 40-50 gallon range in my boat. I think I just need to do the research here and choose my best option. I would like to avoid going custom built for this as I am trying to keep the costs down.

Mine had different dimensions, but I found the best price for the moeller tank on iBoats

at the shop I work at I heve seen many ( ATTWOOD) bulbs leek air and cause a loss in preasure. I recomend replacing the bulb and put a preasure tester in the output and see what you loose . but also always change the filter when any fuel suply work is done . JUST MY 2 cents

always use a primer bulb sold by an engine manufacture ie: merc/Bomb/yamaha/ Zuki.... The primer bulb will rarely stay hard while the engine is running, you have to overcome what the engine is pulling to get the bulb hard, and once its pulls that fuel, its starts to go down, you're keeping the bulb under vacuum. I would normally go straight to the low pressure pump, but they actually give very little trouble. Pull the pump off the valve cover with teh lines still connected and pump up the bulb, if you have fuel leaking past teh diaphragm, you know the pump is bad. Easy way to test the fuel system is to buy a fuel pressure test kit, they sell them at the auto parts stores for a reasonable price. One thing most people over look on Zukes are the high pressure fuel filter, its not cheap, so it rarely gets changed. If its like most of the engines i work on, the vapor separator tanks needs to be cleaned out, fuel screen needs replacing and then retest, if it still acts up, high pressure pump.

Thanks for that information. I do have the VST fuel screen en route. I'll head to NAPA eventually to get the fuel pressure tester as well!

So now, I'll obviously for (maintenance purposes) switch out the water separator filter, fuel filter, VST screen, and fuel primer bulb and test the pressures in the fuel lines as I perform the work. If fuel leaks past the fuel pump when I pressure test the lines I will replace the $140 fuel pump, if not, i'll return it.

I appreciate the help guys!

Finally got to tear into the motor. Varnish everywhere.... See below

What you're looking at is the fuel from the fuel rails in one cup and the fuel from the low pressure fuel filter in the other.

The other pics are the Vapor Separation Tank and the Vapor Separator tank filter (new vs old). This is what happens when you dont winterize your motor or use stabil...

I'm waiting on my High Pressure fuel filter and it should be testing time!

Also tore off the old (OLD) Furuno depth finder and installed my new (to me) Humminbird 788 ci. If theres an interest in a working 1983 model Furuno, throw me an offer! haha

Today i should also be attacking the compounding, polishing and waxing of the hull.
