    Ok, I really hate dropping the tank, and yes, I've done this soo many times, and never replaced the fuel pump (yes, I regret that). So, basically, since it's now going, I need a new one, but don't want to get the el cheapo kind either. I want one that will last. So who makes em and where to get em? Thanks
    Boss
    ps, a stroker is in my future, so I may need to get a hi-flow one, but who knows.

    Hey, Boss!!!! I thought you had an older truck.......How did you end up with an in-tank fuel pump?

    Canmore,
    Yeah, I had the 75' a while back and sold it. I know have an 89'. TBI [​IMG] And believe me, TBI is sooooo much nicer than carb (my opinion only).

    His profile says 89 k5. As for pumps walbro fuel pumps are great. They are the ones that make them for chevy and ford. You can get a higher flow one through them to. Its the company we use when we supercharge cars to make sure they get enough fuel. In the last 7 years of putting them in we have had only one fail, and it failed in 6 months. The reason for it failing was the guy bpught the pump from us because his old stock pump failed and heinstalled it himself. Well when he put it in he didnt change his fuel filter which was the cause of the old pump going out, so it burned up the new pump. change your fuel filter when you change the pump and go walbro. To find them just search for walbro fuel pumps and you can find the best deal.

    HMMMMMMM........Some day I'll have TBI. You're right though, nothing compares overall to fuel injection.

    I don't know if they make an aftermarket pump for your application, but Carter makes has a great line of electric pumps. I put one on my 84 after a ongoing battle with mechanical pumps(and a worn cam lobe). That was almost 8 years ago and the Carter has never let me down.

    His profile may say 89, but Boss has been around so long I didn't even bother checking his profile. My bad, I guess.[​IMG]I'll never forget that great old blue Blazer he used to own.

    AcDelco makes a good electric fuel pump. That is the only one that i will sell at work. I rarely see one come back.

    Yep cant go wrong with the Walbro, just make sure you put on a new SOCK on the pump when you put it in. Get the sock from Auto Zone, they used to be lifetime warranty on them.

    I will also say go Walbro or AC Delco... have used both in our shop. Unless you decided to just go to a external frame mounted pump.

    since my in-tank pumpp just went out I was considering putting in an electric, frame mounted pump (I too hate removing the tank). What modifications do I have to make to the fuel pickup to make it work?

    Whats wrong with big and wide?

    I havent ever heard of walbro if you all are saying they are good they must be good. The ones that we use in my shop are ac/delco. I have only seen one go bad in 2 years of working there. We do alot of pumps on the 89-98 trucks and 92-99 burbs, hoe's, and con's. Besure to get the strainer and the sending unit replaced while you do it as well as the fuel filter for best resaults.

    Granatelli makes a FI pump that is made for hi psi and hi perf. aplications. Model 190ph can handle upto 425hp and is an intank..I figure that you can get one of these plusa flow and press. reg. and be good to go. Also with this setup when you go toa bigger egine you already have the volume/pressure to feed it.

    If you end up going external pump, either Walbro or Bosch (that's what I run for my TPI). Both are excellent and most/all the TPI swappers use them.

    Nothing. Originally, I simply plumbed in the pump and filter at a point about halfway between the tank and the motor. Then when it was 'clean up' time of the installation, I ran all new 3/8 supply line from the tank to the motor on the drivers side, as well as a 5/16" return line, same side. This eliminated the need for the passenger side plumbing, which will be completely removed. Two reasons for using the drivers side - first, the passenger side had all kinds of lines there already, and second - my TPI has the inlet to the fuel rails on the drivers side, so instead of having to route the lines back across to the passenger side, they come up directly under the power steering pump. NO changes were needed to the tank or sending unit. The pump you have to wire in a power line which is part of the wiring harness (in my case I used a Painless Wiring harness).

    There are pictures of the new pump install on my site, just click below and go to the 'Bosch Fuel Pump Relocation' page.

    Thanks for all the info guys....I ended up buying the Walbro unit, the 255ltr/hr pump. I haven't put it in yet, but I discovered that my engine cut off problem was not fuelpump related, it was actually from the loose steering tilt column!!![​IMG] That thing was sooo loose, 3 out of 4 of the torx head bolts were all off!! everytime I would turn, my motor would quit. very dangerous and scary...finally took care of that. I will put the pump in later though, I did change out the sending unit about 8 mo. ago, and should've put a new pump in at the time!! :( Oh well.

    Walbro Is a good pump. It does include the sock were many others do not. It is very reasonable in price too.
