Hey all!
Thought I'd post a couple pics of some current custom work going on at PFS. What we have here is a new top hat being modified to support both an externally routed second pump as well as a return from an externally mounted FPR. Things get crowded when you add electrical connections, an output, and a return to an already busy top hat, which is why we take care to precisely locate all of the connectors.
Having the second pump routed externally pays an enormous dividend in flow capability, as you're not bleeding off into the stock-bucket venturi (if bucketed) or any of the drivers side in-tank tomfoolery. Due to the extra parts, install is going to require some more cursing to get 'er all done, but if you know that going into it and take your time, it's completely doable. What are the advantages?
-Depending on configuration, ~10-40% more flow capability vs. routing through tank internals, which means a cheap, reliable, and readily available Walbro 450 gets the job done long past the point the other guys are messing around with walbro 525's and beefed up electrical connections required to support them.
-External FPR keeps fuel pressure very steady, which is good for both upgraded DI systems and PI. You can even add a boost reference line if you so choose to (fuel pressure climbs with boost).
-Return dumping on top of the bucket is another factor to help avoid starvation issues.
There are many means to achieve your fueling goals/needs. This particular method is simple, cost-effective, and flows a TON of fuel. If you need this or something like it shoot us a PM or email!
