fuel line routing, suggestions?
Ok guys while my motor is out i plan on taking out my current setup (rubber hose from the fuel cell up) and installing hardline. I also want to get rid of the plastic fuel filter. I have a canister fuel filter left over from another project and gettin ready to order the SS fuel line. Heres how i kina of have it planed. Put the filter on the firewall andhave the feed line goin into it from the passenger side, then out into a fuel pressure gauge, back down to the mechanical fuel pump. Does anyone see a problem with this? Any suggestions would be awesome. Im only worried about the waythe fuel line is gonna have to go up and of course that makes even more line its got to flow thru. I thought about installing the filter on the frame, but i think i would like the ease of changing it on the firewall. Anyway just let me know what you guys suggest.

I think it is 16" from the flywheel for NHRA . I mounted a regulator there and it was questioned during tech inspection . They let it go with a get it moved , but I moved it .

Re: fuel line routing, suggestions?
I dont remember if there was/is a specified distance, but definatly do not mount anything fuel related on the firewall. Move it to the fenderwell, framerail, whatever. Just not on the firewall.
From the fenderwell, or where ever it gets mounted, you can use either braided line or pushloc line and aluminum fittings to get it to the engine. The way you have it in the pic showing the original way is fine, and you can hardline it from the fuelpump up to the carb. Now me personally, here is how i would do it. Fuel line down the inside of the framrail, box the rail in at the point it passes the bellhousing. flex line over to the mechanical pump. If your using that fram filter, my opinion is mount it after your mechanical pump, mount it on the engine, somewhere off the front of the head or so. Hard line it from the pump to the filter base. Then either hard line it to the carb with a T fitting and gauge off one branch of the tee, one into the carb, and one end the fuel line going in---or just use braided or pushloc line from the filter to the carb---still using a tee for the pressure gauge. You want to read the pressure as near to the carb inlet as possible. I hope that helps, if i need to explain it better, let me know.
