Fuel hose / grommet questions for 1977.

[nonfatmatt]

I have a 1977 Kombi that I'm working on changing out a fuel pump / fuel filter.

I was able to get some 5/16 hose to go from the tank to the fuel filter that fits fine, but I'm having trouble finding the 11mm hose that goes from the filter to the intake of the fuel pump.

I've found this locally:

However, I'm concerned that it's only rated for 35PSI. Is this enough for my bus?

Also, I've been doing some research on fuel line replacement kits from Bus/Vanagon suppliers. Apparently there's a grommet that connects the gas tank through the firewall. Now that the tank is drained, would it be a good time to replace this? Thanks for your help.

thats on the intake side of the pump, so it won't really see any pressure at all.

I have found that 30r7 or 30r6 hose will only last for a few years in that application because it can not handle the ethanol laced fuel we have to buy these days. Some people say that they don't have a problem with it though, so it may vary by brand. As Rustbus days, there is little pressure at that location, somewhere about 1 psi.

This stuff claims to handle ethanol, etc.., no specific spec numbers offered though https://www.summitracing.com/int/parts/cel-65129/overview/

Ok, thanks for the info. I've decided to do it anyway because the bus needs to be inspected so it can be registered. Quick question, does anyone have any idea which wire is ground and which is hot?

I've got a black wire and a reddish/orange looking wire that went to the last pump, but everything was so corroded it's impossible to know, and we can't figure it out using a meter.

Before you consider which hose or which wire,....buy a fire extinguisher.

Matt where are you in the Sacramento area?

Somebody'd been messing with your wiring, the fuel pump power is red/blue and the ground is brown, no black wires involved in that part of the system.
The fuel pump is G6 (current track 71) below.
