    Tank replacement for EFI

    @SquareRoot Are you connecting the fuel injection supply and return rubber hose to any of the original metal fuel lines or running rubber hose from the tank all the way to the engine?

    Tank replacement for EFI

    Thanks for the pics. I'll have to lookup the weatherpak female connector or just hard wire it. Do you use all rubber line rated for fuel injection or off brand like evil energy? Gates 42195653 3/8 for feed...

    Tank replacement for EFI

    @SquareRoot I really appreciate your help! I updated my previous post and will probably go with: Delphi FE0114 pump Dorman 692044 sender? - Seems like this is the only sendor for a fuel pump. Or order a TBI pump housing assembly and swap out the pump?

    Tank replacement for EFI

    I think I’ll order a 87 tank for the driver side and use the vortec truck in tank fuel pump if it will support my 500 hp motor. Or will use this pump sometime mentioned here https://www.summitracing.com/parts/aei-11569 I’ll just bypass the valve and wire and plumb the driver side tank as a...

    Tank replacement for EFI

    Hmm, I seriously considered the pro flo 4 system but I just put a rpm intake on my new motor and got the sniper 2 complete kit for $1500 out the door. I guess I could resell the Holley pump if I don’t use it. The sniper 2 kit I got came with a Holley external regulator...

    Tank replacement for EFI

    just purchased sniper 2 kit which comes with external pump, regulator and hose. My 79 K10 has the dual 16 gallon side tanks. I just installed a 500hp blueprint 400 crate engine. I’m guessing I can’t use the 96-99 vortec in-tank fuel pumps? If I go with the external Holley pump, can I just run...

    How much HP will a th350 handle? New motor!

    Have had the Blueprint 400 installed for over a year. Haven't put but 1k miles on it as it stays parked for the most part during the winter and I have other vehicles. https://www.summitracing.com/parts/mll-bp4002ct1 It runs very strong and the ol TH350 is holding up so far so good. I replaced...

    Np203 part time conversion?

    There used to be 2 part time kits available to change the np203 from full time to part time. I did the cheaper mile marker kit which you could convert the tcase from full to part time while installed in the truck. Took an hour or two but super easy and straightforward, you just swap a gear which...

    New here, building a 82 K10

    USA1 better than LMC or pretty much resell parts from the same supplier? My truck needs cab corners, quarter corners, lots of interior if I want to make it mint.

    pulls to right quickly if you let go wheel,zero tire wear for 18yrs.

    Could be a sticking driver side caliper or deterioration of driver rubber brake line (deteriorate from the inside and act as a check valve which allows brake fluid to caliper but doesn’t release pressure when off brake pedal.)

    How much HP will a th350 handle? New motor!

    My truck is 4WD and the crossmember supports the transfer case. I believe it’s as easy as moving the stock crossmember back 3” and drilling new holes in frame. Issue is you have to shorten rear driveshaft and lengthen front driveshaft. I’ve hear of some people moving motor 2-3” forward. But...

    Lares vs Cardone steering box reman not Saginaw?

    Here’s a quick video of the steering box flex. Can’t see any cracks in frame and all factory rivets are tight.

    Lares vs Cardone steering box reman not Saginaw?

    Had my assistant move the steering wheel and the steering box responds along with the rest of the steering with the slightest movement of the wheel. I didn't realize how much the frame flexes when rocking the steering wheel! I checked for frame cracks when installing new steering box and there...

    Lares vs Cardone steering box reman not Saginaw?

    The rag joint / coupler is the difference. Cardone steering Box used the dorman coupler that has more splines and the coupler has a mesh metal webbing layered in the rubber. Lares coupler is all rubber and less splines. The steering shaft bolts to either coupler and doesn’t contact the...

    How much HP will a th350 handle? New motor!

    Thanks!!! I couldn’t build my current 400 to those specs for that price and It’s a new block, no steam holes, etc. thought about LS swap but that’s a lot of work to get everything working, gauges, mounting points, etc. I’d rather keep it small block 400 powered. ETA shipment from summit is...

    How much HP will a th350 handle? New motor!

    Good point. I’ll relocate to near middle of intake and possibly change to metal filter. I like being able to see through the plastic filter for fuel flow and debris.

    How much HP will a th350 handle? New motor!

    I put Mobil 1 full synthetic in the transfer case. Can’t remember if it was 10-40 of 10-30. I should prob change it again anyway. I did the full time to part time conversion prob 12 years ago. It was the cheaper conversion kit with needle bearings not the better mile marker kit where you...

    Lares vs Cardone steering box reman not Saginaw?

    Replaced steering box, coupler, center link, and drag link. When just replacing steering box I noticed there is a little less play vs the old cardone reman. Still some dead zone in the center but apparently that’s how these were new. Old Center link was tight but boots tore so replaced that...
