ok so i ran into a problem and i need some info. there is a hose from the gas tank to a little tank into the hatch and i don't know what size it is. what kind of hose and how thick i should i buy? and how many quarts of oil do i need for the 300zxt then i change my oil? and what is the best type of oil filter?

 

oh god... oh god.... ima pop you. its the same size hose as the fuel line, take a piece to the auto store and have them match it, get 5 qts of oil, use until you read oil on the dipstick at the ideal level, theres no real answer to that question, then start the car, re-check the level and add as needed. anything but fram is the best oil filter, honestly though, OEM is the best (as in a nissan oil fliter). youve been here since july of 07 and you just asked like really, questions on such a noob level.... for shame....

 

i just wanted to be 100% sure and the fuel line only comes in 3/8 and it's tiny and im not sure if it is vaccume hose or fuel line. and im sorry snw that im not so good with cars that's why im going to go to uti as soon as i pay hoov off.

 

no apologies, but u really should try researching it. u said its from the tank right? to the charcoal canister? cause that one is standard fuel line, it has other ports on the canister for vacume though.

 

fuel line comes in 1/4, 5/16, & 3/8in for most cars, and my Z uses 1 gal of oil... that leaves it at the full mark... and I found that 15w40 diesel oil works great... I've used 10w30, 10w40, 20w50 in reg oil & Mobile 1 15w40, the funny thing was the Mobile 1 was the worst one LOL...

 

calipers calipers. get some. you might find some for a dollar. but, i agree with everything already said for the record

 

what do you mean get calipers? and snw which line is vaccume and wich is fuel?

 

uhhh..... que? bigger one for fuel tank vent, unless the 240's didnt have the vent for the charcoal canister but i dont see why not. gots pics? ur so needy lol

 

its a vapor tank or what the diagram calls reservoir tank does not hold gas just keeps the fumes

on my external hard drive i have a diagram that has all the hose sizes for 240-260 ill try finding it later

 

Wait a minute... you trying to tell me they have repair manuals for these here carz? And these repair manuals have lots of info in 'em? And they even have pictures in 'em? That just blew my mind!!!

 

ok now im broke again. so im postponing it till my tax return. and i say a funny looking 240z today or it may have been a 260 it had a whale tail and custom wide body kit.

 

get calipers means go to the store and buy them. it's a measuring tool. to measure diameters and stuff.

 

ohh ok...for what?

 

I think he just explained the "for what" part.

This is a caliper:

 

ohh i get it for the hoses right? well i don't need it but im going to get one asap i pulled all the hoses off the car and am going to take em to napa when i get more money.

 

meh. i like my Mitutoyo Digimatics better

 

whats that e? like a digital one?

 

***** expensive

 

im just going to buy a cheap one. but hey snw do you want your rainbow brite collection back?

 

cheap=inaccurate.

 

fine then i'll go out and get a decent one. and does anyone have a hood scoop for a 300zxt?

 

there is no such thing for an '88.

 

Since you've pulled the hoses already, Napa will measure them for you. Hoses are sold by the inside diameter and by the use for which they are intended. Fuel hose is different than heater hose or vacuum hose. The vapor hoses for what you need are braided for extra strength and are bigger around than what is now available. Those calipers won't do you any good because they are in thousandths of an inch. The hoses are metric as in 8mm etc. Unless you know your decimal/metric conversions just take the frappen hoses to the store!

 

i will that is my plan but i have to wait till i can pay for it first. ok e i want one for my 300zxt does anyone have one from any year?

 

haha a friend of mine got a set of those nice one's with the guage for around $200 and they broke in a week or 2. lol the machinist at the boat yard we were working at tried to fix them (yea right.. i saw this coming) and just demolished them. springs and gears went everywhere lol.

anyway, cheap one's usually have metric too. and they will surely be accurate enouph to measure hose with. for that matter, all you needed was a ruler to answer a third of the original question.
hose wont cost that much. you could probably re-run every fuel line on the car for about $50 (guestimate). and you won't need nearly that much for what it sounds like you are doing. i'm just saying not to spend too much time saving if it could save you some time on getting the car fixed...
