mobythevan Posted March 27, 2003 Share Posted March 27, 2003 So I have searched through a boatload of posts here and at zcar.com about the turbo swap and have found all of the info I need, but have at least one question about fuel tank. I dug up one post that said a 75 or 76 tank will fit into the 240 and work better with the FI(but 77 on would not fit). The post only said that the tank had baffles inside to reduce sloshing. I can't find one of these tanks so I will be using my 240 tank. I realize I will have to add the electric fuel pump, damper, filter and new lines up and back to the engine. I guess the question is what size fuel lines should I run and what specifically is the issue with the 240 tank(the size of the fuel lines/connections on the tank?) What are other people doing here that kept their 240 gas tanks? Thanks Bryan Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted March 27, 2003 Share Posted March 27, 2003 One option that works well is to use a surge tank like in the JTR manual. It has worked well on my FI v-8. Quote Link to comment Share on other sites More sharing options...
Mudge Posted March 27, 2003 Share Posted March 27, 2003 I am going to run the 240 tank for awhile. I'm using the 5/16" fuel feed as a return and 3/8" new line on the bottom of the tank (drain plug) as my new feed. Without having a rubber bladder or etc inside the tank, any fuel slosh on a low tank can end up sucking air, and that will cause detonation, detonation = death. On stock cast pistons probably a good to fair chance of instant death especially under hard driving conditions that will usually cause slosh. So as a precaution on the street I'll be running a 1/2 tank or more always until fixing the problem with a cell or new tank, and on the track stay to 3/4 or above.

Guest Rangerz Posted March 27, 2003 Share Posted March 27, 2003 I had a sump welded to the bottom of my tank. You can get them from summit or jegs for ~$50. It has 2 outlets that are 3/8" at the back. You cut 2"holes in the bottom of the tank and that creates a "baffle". Make sure to take the tank down to a radiator shop and have them clean it out for you before weld!!!!! Quote Link to comment Share on other sites More sharing options...
mobythevan Posted March 27, 2003 Author Share Posted March 27, 2003 Those ideas sound good, I have a spare 240 gas tank from the V8 car that will not be used for anything. I will set it up with a sump and baffle design to go in the car. Just to get the car fired off I will use Mudge's suggestion to use the drain plug as a source with a filter before the electric pump. Thanks guys Bryan Quote Link to comment Share on other sites More sharing options...
BRAD D Posted March 27, 2003 Share Posted March 27, 2003 This is what I did, for more info got to this link. http://www.hybridz.org/phpBB2/viewtopic.php?t=18590 Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted March 27, 2003 Share Posted March 27, 2003 Aren't you worried about a piece of road debris getting caught up in those beautiful lines and ripping open a fuel line? Quote Link to comment Share on other sites More sharing options...
BRAD D Posted March 27, 2003 Share Posted March 27, 2003 yeah I might run them a diffrent way, from the back of the sump to the side. The car is still sitting up on jack stands not running so I have some time to think about it. Quote Link to comment Share on other sites More sharing options...
