For a 3.2 conversion that I was trying to bring out to a meetup on Sunday. Relocating my fuel pump to a better up front location, under the steering rack. Redoing some of the hose connections to make them longer. 8mm, 10mm for most of them from the tank and the supply and return lines in the car.
The Bosch fuel pump I have needs 12mm, maybe 13mm to get over the bulge. I have; 5/16 hose which is 7.8mm, good enough for the 8mm connections. 3/8 which is 9.5mm, good enough for the 10mm connections. I tried everything to get the 3/8 to stretch over the 12/13 mm needed to install on the feed side of the fuel pump. I tried heating in the sun on a black car, lazy way. Then I tried a heat gun. Then I tried needle nose pliers to stretch the hose opening out. Tried alcohol to slip it over. Nothing I did would get more than a 1/4 over the fuel pump inlet and then it would bunch up and not budge any further. Then I went to the store and bought some 1/2 inch which is 12.7mm. Fits great over the Bosch fuel pump, but is too sloppy over the 10mm supply line from the tank. And I don't have a fuel hose clamp that big yet. What's an idiot to do? I spent a day on this and am not much further along and I still need to wire it! All of the hose is the good stuff from NAPA, Gates Barricade for fuel injection. Help |

Once this is running leak free, I may go back and do it the really right way. It cracks me up to walk into a FLAPS and ask for metric hose. They bring out 3/8 that has 9.5mm stamped on it and say see, it is metric.
Another local suggestion was this; Cohline from Bel-Metric. https://belmetric.com/hose/ Maybe I'm being Roadkill and just want to get my junk running, I'll fix it the right way later. I'll do some shopping and look for the ultimate answer. What would an F1 team do??? |

I’d be looking at pumps. 1/2” inlet is overkill and leading to this issue. Like Ninja alluded to - ultimate solution is in-tank pump. If memory serves me Tygaboy did some primo work to put a Holly in-tank pump into the LS conversion. @tygaboy |
