While I have most of the reference books about PTs including At Close Quarters I have not been able to definitively determine the number and volume of the fuel tanks in the Elco PT-103 class of boats. The total fuel capacity was 3,000 gallons. I have seen descriptions saying there were three tanks, but the plans I have seen depict only two. On the other hand, I recall reading or being told that there were three tanks, one under the floor of the dayroom and one on each side of it. The deck plans for this version of the Elco call out three deck fills.

If there were three tanks, were each of them 1,000 gallon capacity? If there were only two, were they each 1,500 gallons capacity. Or was it some other combination?

If anyone has this information they can post it here or e-mail me directly at cmfaure@earthlink.net . Thanks much.

C Marin,

There were three (3) fuel tanks in the 103-class (and later) 80' Elco boats, holding (I would think?) 1,000 gallons of 100% octane aviation fuel each. I don't think the tanks were self-sealing at the beginning of the war, but were made so at some point in the production run.

I've seen line drawings in the past by by Dick Washichek, this website's moderator, of the 80' Elco's mid-section, clearly showing the three fuel tanks under the dayroom, either on Dick's website or on this Message Board in the past. The drawing perfectly illustrates the shape and positioning of the tanks in the boat.

The center tank which was located under the day room held about 1,500 gallons. The port and starboard tanks held about 750 gallons each. They were located under the deck on each side of the day room. I hope that my memory is still good.

From the ELCO parts book:



The parts book only lists them as center and wing tanks, no capacities. Interestingly, there were about six different fuel system configurations in the 80' boats, and they occured within consecutive hull numbers.

Regarding the aluminum tanks, to give a little perspective as to their size, look at the oval shaped plates. The plates could be removed after steaming the tanks and a medium size man could enter to complete the cleaning. The view is from the top of the center tank and the inboard side of the wing tank.

Going through various fuel tank related drawings on Dick's DVD, the closest I found to given tank sizes was the maximum gallon markings on the dipstick drawings:
Center:
1265
Wing:
844

Another (later) dipstick drawing showed maximum markings of 1250 & 800.

Very close QM, excellent memory!

In the Ron 10 boats we used the verbal data that the center tank under the dayroom deck was just under 1500 gallons and the two side tanks were nearly 1000 gallons each. Our all aluminum tanks were replaced with self sealing tanks in Saidor when the new engines were installed. We heard that the task proved to be too complex to do thereafter in the field.

Here is illustration I took from my old 2008 ELCO PT Boat Calendar. It shows the dayroom and the fuel tank arrangement. Hope this helps some.

I have attached close up images of the early 80 foot Elco fuel Levelometers the port or wing tank meter is not as clear to read but give a good indication on fuel capacity.

How many tanks on a Higgins? Seems to me there were four.
