Chief buggy

So looking at doing fuel plumbing next. i am looking at 2 speedway kits. One has AN fittings already brazed to the filter/regulator. This would mean less fittings and cleaner overall. But not parts store replaceable.

The other has the GM release fittings, so 2 fittings to attach hoses. But the filter/regulator would be parts store replaceable.

When I was building my jeep, I had a lot of people raise concern over the filter/regulator you have shown. They said the results were hit and miss if it provided proper pressure, and flowed at the required flow rate needed for a V8. I had it all plumed and ready to rip, and decided to use a factory fuel filter/regulator. Yes, there are some added fittings, but it gave me peace of mind.

why not use an OEM gm setup with an intank pump?

Thread 'GM Fuel Quick Disconnect Lines'

As I build my buggy I've been trying to collect parts for the next phase so it's on the shelf and I don't get burned by the random parts shortages that seem to be going around. Next money drain is fuel cell plumbing. I'm running a Goatbuilt cell with GM Truck in-tank pump that he recommends. I plan to run return-less fuel setup using the Corvette filter/regulator.

From the regulator to the fuel rail is covered. But before I buy 4 fuel disconnect to AN adapters, are there some factory pieces that I could scrounge up and not have adapters on adapters to adapters?

This would be factory...
 
No opposed to in-tank, but i have a pretty limited flat spot on the cell, I have the filler, and pickups made, etc. And i have had good luck with external pumps,etc.

That's a Corvette bypass regulator is it not? Or maybe an aftermarket of the Corvette unit. There's thousands of those things that came from the factory installed in Corvettes as the name implies. Maybe at really high HP numbers you could run into flow issues, but it seems that most folks on this site like to grab a 150k mile engine from a boneyard to put in their rigs, so those regs should work fine.
 
^^^ correct and for what they cost i would add a spare in the trailer box. Just the exclusivity of the AN fitting had me go hmm

I did the same on my buggy so that I could get parts anywhere.
Not a V8, but no leaks and works great.
 
I ise a E2000 pump and the quick connector AN fitting on the outlet. It's fine I just use the one that threads together not the push on version.

I thought those were only good for mid 40s psi and thought he a higher pressure.
 
Never had a problem with the vette regulator filter, We've been using them since the first ls engines hit the junkyard. The Chinese make a pretty ****ty copy so I use the Delco ones.
Fuel pumps have always been a problem even buying name brand off the internet. I suspect most of what's online is fake Chinese junk. Lately I've been ordering pumps direct from deatchworks. Super quiet and reasonably priced.
 
Now yall have me worried about external pumps/pickup. I have a the tank all ready to go with walbro pickups, feed, return, and vent.

soccer moms suck those suburban tanks dry running braxton to lacrosse and sadie to cheer, i fail to see the reason why everyone feels the needs to do all complicate these things.

lol they also dont stand them on end or lay them over...
 
People have been running external pumps for years with no issues. Just try to keep it below the actual tank level so it's doesn't have to work as hard. Still easy to keep a spare and swap/diagnosis any problems.
 
ive been running a bosch external under the driver seat with the corvette style filter reg. I do have a pre pump filter as well. its always kept the buggy running, nose up, nose down, on its side etc. Easy to change out on the trail when it dies. In tank will likely last longer but can be a bitch to change depending on cell type.

both work fine. dont over think it.
 
I've been running Airtex and Walbro external pumps for two decades now. I understand the argument for in-tank fuel pumps and if I were currently building a truck I would go that route. The last time I replaced my external fuel pump on my buggy, I went with a Walbro GSL392 . I got it from Summit and it showed up as a TI Automotive fuel pump. They are Walbro, some of their high performance pumps are branded TI Automotive. So far I have not had problems

I have four Walbro pickups and a Corvette FPR ( WIX 33737 ) just like you are planning on running. Just run what you have.

I only ever ran out of fuel once. Tank almost empty, on my roof pinned into a tree on my side for awhile trying to get unstuck. Hydramat couldn't pull fuel that was now above it.

Guys grabbed fuel from camp, pulled me out with a winch, cracked a line at the rail to bleed the air and fired right up.

Same e2000 still going strong.
