Hugh Posted September 20, 2004 Share Posted September 20, 2004 I am going to be bringing my car into the shop for the SR20DET installation. However, I am trying to prep everything as much possible to speed up the install and reduce my cost for their work done. I’m going to run the SR with my Electromotive Tec3, and I will have it all pre-wired before I bring it to them. (I had it running in my old car, so I know the harness is built correctly) I have an SU L28 in there right now. I want to put the Walbro 255lph pump in the rear. My question is whether I can install the pump before driving the car 40 minutes to their shop? I realize the fuel pressure would be way too much for my carbed L28, but I’m not sure how else to handle this. Maybe run the fuel lines and prep it all, then swap out the pump last thing? I guess I could piggy back the pump and lines, then just change the main line off the tank to the new pump at the shop. Later on, in my own time, I can remove the entire stock fuel system from the vehicle. I’m in the brainstorming phase, as well as ordering parts. I will begin the prep work probably next weekend. I may actually start laying the Tec3 in there sooner. Any ideas you guys have for me, fire away. This system is going to have to support a buttload of power. It will be over 400hp before it hits the road… so I want the fuel lines to support it. I don’t want to pay the shop to do this menial work for me, though.

dapiper Posted September 21, 2004 Share Posted September 21, 2004 Recommend mock install. Do not use EFI pump on SU's. Float valves will blow open and flood badly causing fire hazard. It will not run, anyway. Rewire pump direct to batt thru fuse and relay with AWG 12 wire. Don't use stock wiring. Use 3/8" hose or AN8 line for supply.

Hugh Posted September 21, 2004 Author Share Posted September 21, 2004 Ok, that all goes along with what I was feeling. I was pretty sure cranking up some high pressure EFI pump on a carb was BAD idea... even for only 40 minutes. I was just throwing that out there to get some ideas. Seems you like my plan... run the entire new fuel system and have it ready to go online with the switch of a hose. (oh, and I was planning a nice relay job for it as well, thanks though!)
