Anyone upgrade to a 1/2 inch fuel line? I am planning a fuel system upgrade and with the new Robb Mac SU for the first gens you have the option of going bigger than 3/8, I am going with their larger pump too. For those that did upgrade where did you get the line from? Thanks!

Just did mine last weekend. I got a pre bent SS line from Inline tube. With shipping it was about $180. The 1/2 is a very close fit but was just off a little in a few places, not a big deal.

You can't use the normal clips so had to use some aftermarket clips and drill some holes. Inline sells the clips and some really nice bolts for the job.

I have a RobbMc fuel pickup with 1/2 line and fuel filter with 1/2 barb fittings. It should flow real good but will be a couple weeks until I fire her up.

I will try and get some pics next time I work on it.

Thanks! Did you have to special order that? I did not see it in their catalog online.

Hey Tony! I understand you have to call them. When I was looking to upgrade to 1/2" I ran into the same thing not seeing it in the catalog. I bought some SS tube and bent it myself but if I would have known I could order it, that would be my first choice.
Dont forget you need to upgrade your pick-up too.

Yup, going with the RobbMc pickup/sending unit and their fuel pump. I also like that the sending unit will allow me to hook back up the vapor return line my car has.

Now all I need is someone to install (hint, hint)

Yes I called inline tube.

I found that the gas tank staps have a small slot that I used to mount the RobbMc filter with a rubber line clamp. It worked really well with a short 10/32 button head screw throgh the strap. I had the gas tank out for the RobbMc fuel sender. So with the gas tank out I put some sound deadner (Second skin) sheets under the trunk.

I did a test fit and found the hose clamp screws would hit the trunk floor so I shaved them down on the head and the opposit end.

I used a quick disconect connector filled with dialectric grease on the electic line for the gauge. It was emotionaly hard to cut the brand new factory end.

I was also very carfull to mark the filter direction and the sending unit lines for direction (in/out). Its a pain in the but to drop the tank and most likely I would forget wich side was wich. BTW the RobbMC is a 1/2 in and Out.

I also found that I had to get all my barb fitting and adapter at a hydralic hose company. I stoped at Menards, lowes and Home Depot and knowone had the right fittings. Plus the hydralic hose place had the thick blue 1/2 gas line.

Very nice. So the robmac unit doesnt run a sock? I didnt run one either. I had a welder plumb a hardline right into the tank. One concern I do see is that the return might aerate the fuel at the pickup. I would tweek that return to angle it away from the end of the pickup.
Ahh Tony, so much work, so little time!

Thanks for the pics!

Danny, I need to do something fairly soon as I smell fuel fairly often when I get on it,also when I filled up on the way back from PSN (I over filled it a bit)it was leaking from the top. So rather than risk it I'm going to re-do it all from the tank to the pump and put in a bigger pump while I'm at it.

Time is an issue, so I will probably take it to a shop, if I can find one somebody recommends.

No sock. That is the reason for the external filter that Robb recomends.
