stumped on startup.

[smoken u]

ok so im still getting air into the fuel system, so im going to replace the lines front to rear, probably just use rubber fuel line, instead of the hard plastic thats on there, and i will for sure bypass the water seperator. just another question here, are all the fittings on the tank and filter of the same size???

Strength to weight ratio is better for aluminum than steel.  Strength to weight ratio is WAAAAAYYYYY higher for fiberglass than for aluminum.

an aluminum boat is way lighter than a fiberglass boat. taking similar boats with similar equip and similar setups. you have to use lots of fiberglass to make a boat as strong as aluminum. and that makes the glass boat way heavier than the aluminum one. so that kinda messes with your statement.

you will never convince me that a pound of fiberglass is stronger than a pound of aluminum. more flexible maybe.

all the boats up in bristol bay, AK, are all right about 32 feet. 99% of them are fiberglass. the best/fastest/lightest boats are all made from aluminum. im not just saying that either. there is only one boat in bristol bay that will plane out, and surprise surprise, its aluminum, and gas powered. most of the other boats are fiberglass, and none of them will get out of their own way. even the ones with plenty of power, cant get up on plane. the hull is just too heavy to get up out of the water and work like its supposed to.

my dad and uncle have an aluminum boat, with two 350 horse 454's, and two 14" Berkley jet drives. (not an efficient drive train at all if you ask me) and it still gets twice the economy any other boat gets. there fuel bill is literally half that of the next most efficient boat.

if fiberglass is soo much stronger/lighter than aluminum, why do the FG boats weigh soo much more than a comparable aluminum boat? you gotta use LOTS of fiberglass to build a boat.

im really not trying to argue, but your statement conflicts with my life observations.

sorry for the thread hi-jack.

I would try eliminating the "pre-heater valve" on the fuel filter. You have to splice the line together and also use the older style filter. I swapped to a Stanadyne filter setup on my cars and it just about got rid of all the air. You could try a new o-ring under the pre-heater valve. That could be all you need.
