hsr fuel pump
well after more than 3 years I have my 383 HSR swap done. I got the sub frame in, new transmission, exahust, steering box and brace, suspension, ball joints, tie rod ends, ect ect ect.
I am trying to finally fire it up and now the in tank fuel pump wont fire after sitting all these years. The HSR came with a fuel pump. Can I just pull through the old one or do I have to drop the tank and pull it out? Just was hoping to avoid taking that exahust and everything apart to get there. UGH!!!! always a road block, nothing works first time.

Re: hsr fuel pump
i heard that banging on the tank and get vibrations in the tank can get a fuel pump going that has been sitting for a while. So the only option is new pump if that does not work? You can not pull through and old one?

I'll do that tomorrow. The guy I was working with didn't show today. When I took the tip harness off I hope I didn't mess that up

If the pin out is the same as my 89 you can run a hot to pin g on the aldl and see if the pump runs. The fuse is near the battery, behind the headlight. One orange and one red wire.

Re: hsr fuel pump
Banged on the tank, put gas in it, and got the wires before the fuse and hooked it up directly. We have to bypass that relay I found out as the new wiring harness with the HSR has a seperate wire to trigger the fuel pump. The other wiring harness that I left on know I am wondering how many more electrical things are not hooked up in the dash
! Anyway fuel pump working thanks!
