I got to admit the banjo are the tightest spot for the fuel to flow though... But the next problem is the size of the fuel line. The stock fuel line measures out at about 6mm ID ans the Vulcan Big line Kit is 1/2" (or 12.6mm) which is double in size compared to stock lines...
I'm not knocking Gary's idea... But it is limited for that amount of HP/TQ it would support. I would use Gary's idea on a stock powered engine but I would upgrade to Vulcan Big Line kit if you plan on any increase in power...

What kind of pump are you running there Gary?
Sure isn't a Carter Campaign or a OEM Stock LP pump...
I'm pushing 381/826 and 379/831 and using a Carter Campaign on a Vulcan Big Line Kit keeping pressure above 10 PSI all the time. But that wasn't possible with the stock lines for me. I could suck it down to 5-7 PSI on the stock banjos and lines... They were not drilled out...
I guess it can be done then... "give:

YUP - but the Walbro is just an experiment - I had been running the OEM LP along with a Carter pusher prior to making the pump change to the Walbro - and in general, the PSI measured at and delivered to the VP-44 is the same as it has always been, and all the OEM banjos are still there, just drilled out as described.
And don't forget the statement I STARTED this thread with:

Some guys go to the expen of larger lines and fittings for the fuel system, but for moderate power up around 400 HP or so, the stock lines do a pretty decent job.
