here we go again...**pics*** DONE!

newer truck ie tbi and stuff had a fuel filet on the fram rail and some in the tank.

hmm when i pulled mine apart i just stuck the 1 1/4 or w.e size it is wrench on it and turned it came loose:laugh: :haha: good luck man. keep your head up and DONT quit. thats cheating:doah:
 
Ok I got the hard lines off (imagine that...get the right tools and it comes off like nothin' :)) and I went to Kragen and got a new filter...came home and put it in and put the lines back on.
I cranked it over and it wouldn't fire...then I realized that with a mecahnical fuel pump I'm probably going to just need to prime it then once the engine is running it'll pump fuel through the lines...
So I ran down to the gas station and got a gallon of gas and my dad poured a little in then I fired it up. It fires right up and idles like a champ....for about 5-10 seconds (when it runs out of fuel) then it dies...but here's the catch...the sound that its making right now when it runs out of fuel is the same exact sound (and feel) that I felt on the freeway on thursday when it kept trying (and did a few times) to die on me....so we're thinking there's something wrong with my fuel pump...

Are those hard to change? I'm going to go outside and look at it to see...
 
nah just 2 bolts,1 or 2 harlines, and 1 or 2 rubber lines.

off topic but does anyone know if the fact of getting a fuel pump that has a higher gpm increases power?
 
iono but it might decrease mpg :)

ok wait..so it unbolts easily....so two hardlines...one in from the gas tank and one out to the carb...then two rubber lines? Are these vacuume lines that make it pump?
 
no there is a "driveshaft" that spins off of the crank that pumps the pump.

i meant that depending on your truck you either have 2hard and 1rubber or vice versa. mine and prollably yours has 2 hard, one is the feeding line from the tank the other is up to the carb, then the rubber is the return to the tank.
 
or actually i think i got it backwards. regardless theres 3 lines. 1 from tank 1to carb, and one returning to the tank.
 
oh ok...well maybe I should just go buy one and replace it...seems like a worthy investment to be able to rule it out. Once I replace it should I just pour some fuel down the carb and fire it up...will the pump be able to catch up and fill the lines up before it dies in 10 seconds or so or is there another method?

Oh and do I need to plug the lines somehow before I pull the fuel pump off or will it only leak a little?
 
yeah. when i swapped motors in mine. i used a pair of vice grips for the feeding line from the tank. the return line *should* be dry, and the one to the carb *should* for the most part be dry unless it was cranked over recently. it WILL have a little bit of gas in it, but theres not really anything you can do about that.
 
your pump will be able to draw it through the lines, the hard part with replacing those fuel pumps, is getting that push rod up long enough for you to slap the pump on, the rod will fall down in there, it NEEDS to be resting on the lever on the back side of the pump.

You will see the push rod when you remove the old pump, it will most likely fall down and rest on the plate your pump mounts to.

BTW,,,have fun:crazy: :D
 
so when I go to put the new one on there is a rod that just sits on top of this thingy...

yes it needs to sit on the indent on that lever thingy.

yea that the hard part about replacing these things. i dont think that "driveshaft" was the right word for me to describe that...
 
i suck at drawing and the rod is inside the engine. shown in pix and it moves back n forth to pump the thing that its sitting on. to make the fuel go.

Don't let the upside down illustration get you turned around...

And to keep that push rod from sliding back down into your way, you can slather some axle grease on it to help it stick in place. If that doesn't work you there's a short bolt in the front of the block, just around the corner from the pump. You can pull that bolt out and see the side of the push rod, stick a longer bolt in there and it will clamp the pushrod right in place. Makes it pretty easy. Otherwise, you'll soon find out that you weren't equipped with enough fingers to complete the job.
 
Oh yeah, I always like to generously apply the RTV in there too. Helps ward off unwanted oil leaks. There's two places you might need to put it. The fuel pump kinda bolts on top of this adapter plate that goes onto the block. I went ahead and pulled the plate off the block, RTV'd it, and put it back on. Then I RTV'd between the pump and the plate, and bolted the pump on. Stopped that slow seepage I used to have.
 
SON OF A BISCUIT!

This thing was a royal PITA...I swear if I ever lose a fuel pump again I'm going electric and not looking back!

I started @ 8:00 this morning...I'm inside now @ 11:42.....BUT....



















I got it finished! Hahahahhahaha I'm so excited I'm about to burst. I went from not even firing up this morning to now its running like a champ! Better than it ever has ran in the two years or so that I've had it.
Ok to make a long story short I was able to replace the fuel filter this morning and then spent the entire rest of the day replacing that god forsaken fuel pump...boy was that a PITA!

Oh....oooooo buddy...this.....this freaking thing was enough to test my religion....

So now its done and running great...I'll get to take it to the car show tomorrow...and I did it all w/o a shop...just me and my dad and a lot of time :)



 
Congratulations man! I'm really glad you got it all figured out. I know exactly how you feel. I started replacing fuel pumps the day I bought my truck. Even got a bad one from the store, which really makes you want to destroy things after all the effort to get it in there. Had bad lines and a bad tank switch too, ended up running a hose out of a gas can in the bed! Took me 3 days to get it home after I bought it, and it was only a 40 mile trip! Spent countless hours on the side of the road in the middle of summer, and it was extremely frustrating. I just did a fuel pump a few months ago too, but it only took me 15 min this time.:wink1: It's all part of learning. I know this was a big obstacle for you, and you did good pushing through it. This kinda stuff will be cake for you someday soon.
