Re: suburban tow truck fuel issue
If you have (after market), rear A/C, make sure they didn't tie the A/C lines to the fuel line as they will cause vapor lock. On my '85 we finally went to a 454 R/V (HD- motorhome) mech pump, with no more headaches. Good Luck.

Re: suburban tow truck fuel issue
If the fuel line was tied to the low side AC line it would get cold.

Re: suburban tow truck fuel issue
Jack, the factory in-tank pump would have made a nice pump with a return-style regulator, using the factory return line. Could have also been used as a booster pump, with a regulator, for the mechanical pump. Guys around here have done it both ways.

Re: suburban tow truck fuel issue
Check/replace all the flex/rubber line connections, some types of hose can come apart inside or swell blocking flow.
