fuel tank questions

Featured Replies

ok well most of the older forum guys know bout my rig

 

86 lifted carb'd wagon

 

punched a hole in my gas tank this weekend.. thank god for stuff called Seal All.. that and a piece of my pants sealed her up..

 

anyhow, I cant be doin road trips with it liek that so I'ma grab a SPFI tank and stuff it under there. I know I'ma have to use some fittings to make the hoses fit but my biggest question is with a carb'd engine that doesnt have to pass emissions, do I really need the evap jump? theres the 2 hoses coming off the passenger back side of the tank.

 

Will it run if I cap those off and get rid of the evap system? I dont like havin those hoses exposed that close to the tires and I know with the older Chevy 350's we played with in highschool we'd use beer kegs for fuel tanks just fuel out, return and a vent..

 

So what do u all think.. do away with the evap crap? or do I need to keep it? mileage isnt an issue cuz the carb'd junk and I get bout 15 mpg anyways

it will work without it...but keep the "evap" ..it helps to maintain the proper pressure/vacuum in the tank...I cut mine off only to find out on some very hot day, miles into the "sonoron desert" , while driving down a very steep hill ..then suddenly, the car stopped running, ... blowing fuel out the top of the carb..

I would leave them also. There should be a shield covering most of those lines in the wheel well. You could fashion more shielding using some aluminum roof flashing to help cover the exposed areas.

 

And Seals All is some great stuff to carry in the vehicle. I have used it many times to plug a holed gas tank...........

SPFI tanks have the baffles in it also to limit fuel cut on cornering correct
