matt-k 0 Posted November 19, 2007 Im installing my mi16 engine and have in my possesion a facet fuel pump i got of ebay.

ORB 227 1 Cars Posted November 19, 2007 I use a Yamaha R1 pump on my R1 carbs, it seems great, and it auto cuts out when the carbs have enough fuel in them Share this post Link to post Share on other sites
205mattgti 0 Posted November 19, 2007 i use a facet red top pump and a king fuel pressure regulator, had no problems with it I belive (but not 100% sure) that if u use a standard injection pump u will need to pressure regulators Share this post Link to post Share on other sites
mmt 15 Posted November 19, 2007 The original pump produces too much pressure. The valves in the carbs cannot shut with the pressure from the original pump. Use your Facet pump og any other carburetter fuel pump. /Martin Share this post Link to post Share on other sites
taffycrook 2 Posted November 19, 2007 I use the std pumps on most applications for road use. You need a reg FRP09 which drops the pressure to a carb friendly 5-4 psi. Its listed as a turbo reg but just leave the boost input off. This allows you to use all the std fuel lines up to the fliter and the return line. Nice easy solution to the plumbing.

projectpug 0 Posted November 19, 2007 Just done this myself using an fse turbo carburettor regultaor and a sytec pro flo runing my carbs on 3.5 psi according to the pro flow. Share this post Link to post Share on other sites
matt-k 0 Posted November 20, 2007 Ok people, i have a sytec pro flow regulator (the round silver one with large dial on top) i was going to put this onto the fuel line set at the right pressure for the carbs followed by the filter, non return valve then carbs? Or do i put the regulator on after the carbs on the fuel return line the same as a fuel injection set up? As you can tell ive not done this before! Thanks.

If your running carbs you don't need to use the fuel return pipe so rip it out. I run Weber 40's on an 8 valve GTi and use a Facet pump (can't remember the exact model) with no regulator at all and it runs quite happily on road or track.

projectpug 0 Posted November 21, 2007 Well using the twin regulators i had to use the return on the bottom of the FSE reg as thats how it drops the pressure down . Just depends on how you do conversion Share this post Link to post Share on other sites

Just depends on how you do conversion Yes but my point was that if you use the correct pump you don't need any regulator and then don't need to use the return. I've seen people running carbs with THREE!!!! reg's. bloody ridiculous. Share this post Link to post Share on other sites
