At most, I've lost maybe a quart of gas, including what was in the filter. You want to make sure you're parked on level ground, or even parked facing up hill to keep the gas back in the tank, though I don't know if it would make that much of a difference. You just don't want to start a siphoning action on the tank.

 

I replaced mine when I installed a new carburetor. I forgot to uncap the gas cap to let out all the built up air. I think thats what you did Mikey, cuz I lost quite a lot as well. Here's a pic of my filter... The fuel had eaten so much of it away, you could see through it:

 

There is no problem with getting air in the gasline on any fuel injected vehicle. When you start the engine the injectors will open and the fuel pump will quickly build pressure in the lines again. So, no worries guys!

 

I lost probably over a quart of gas. Maybe 2 quarts. And it burned!!!!:cry:

 

guys,

obviously i have not looked at it but is there anyway to plug the fuel line when you disconnect it so that you dont get a burning 2 qts of gas on you?

...or is the line something that can just be pinched off with like a binder clip or something?

 

Latex gloves and another set of hands would really help. There is no real way to "plug" each end, as they are special fittings. So, the best thing to do would be to have someone ready to plug each end of the line with their fingers (fuel inj side and fuel tank side) while you remove the old and replace with the new.

If you're quick, you should lose no more than 1/2 a quart of fuel.

When you start it up, it will take longer than normal because the system is building up pressure.

It's cake guys. Just wear latex gloves and safety glasses.

 

While I have yet to change mine...only 3 months old...I cant imagine it is any different than others I have done. If you look in my tool box, you will find a hand full of golf tees. If the pressure has been relieved, I pop those in the ends on the lines and they normally hold long enough to start the new one on.. but yeah...always goggles !

 

Not on these fuel lines. It wont work. Take a look at the fittings.

Good idea though, I use the golf tee trick all the time.

 

do u think that changing them will increase performance for trucks that havent done it in a long time?

my bud has a chevy z71 and his brother has a 1ton crewcab long bed chevy with a 454 in it. the z71 would beat the 454 in a race... but then they changed the fuel filter in the 454. they raced.... and off the line the z71 was a head by a little, but then the 454 just zoomed by and was ahead. the z71 coulnt catch up. so the fuel filter for the 454 helped a lot!

 

I doubt it, but you never know. If the engine was being starved for fuel, then it obviously would be down on power.

It made no difference on my rig. More of a piece of mind than anything.

 

I did mine about a month ago and didnt need anything more then a small(14"x14")shop rag to catch the gas.I must admit that when I bought my filter at the dealer I asked a Tech. that was out on a smoke break for any hints,he said two things: First disc. the battery to avoid any sparking issues. Second make sure you vent any tank presure by removing the cap.
